Description

Technical Field

[0001] The embodiments of the present application relate to the field of Internet technology, and more specifically, to an information acquisition method, a server cluster, a server, and a device. Background Art

[0002] In the face of scenarios where tens of thousands of large-scale resource monitoring or network isolation exists between monitoring nodes, it is very necessary to introduce a distributed monitoring and collection architecture. Currently, under the existing monitoring architecture, the main function of the master node is to aggregate and display the monitoring data of each agent node, while the main function of the agent node is to collect monitoring data and report it to the master node. The master node is the root node in the existing monitoring architecture, and the agent node is the child node under the root node in the existing monitoring architecture.

[0003] As the amount of monitored resources gradually increases, ordinary users originally only need to view the monitoring information of a small number of resources under their own authority. However, since the master node database stores the entire set of resources, the query efficiency of each operation needs to be optimized to ensure.

[0004] Therefore, when users view the information of target resources, how to share the pressure of the master node and improve the query efficiency is an urgent problem to be solved in this field. Summary of the Invention

[0005] Provided are an information acquisition method, a server cluster, a server, and a device, which can improve query efficiency while ensuring that users can view information about target resources.

[0006] In a first aspect, an information acquisition method is provided, the method being applied to a server cluster, the server cluster comprising a plurality of nodes in a hierarchical relationship;

[0010] Determine N nodes based on the M resource groups, where the N nodes include one or more nodes corresponding to each resource group in the M resource groups, where N is a positive integer greater than or equal to 1, and the server cluster includes the N nodes;

[0011] Determine a target node based on the N nodes, where the target node stores information about the target resource;

[0012] The target node outputs the information of the target resource.

[0013] In a second aspect, a method for obtaining information is provided. The method is applied to a first server and includes:

[0014] Receiving original data sent by the cache server, where the original data includes an identifier of the first resource;

[0015] Based on the identifier of the first resource, processing the original data corresponding to the identifier of the first resource in the original data for at least one preset period to obtain at least one information of the first resource;

[0016] Determining, based on the identifier of the first resource, an identifier of a first node corresponding to the identifier of the first resource;

[0017] The at least one information is sent to a first node corresponding to the identifier of the first node and all parent nodes of the first node.

[0018] In a third aspect, a server cluster is provided, the server cluster including a plurality of nodes in a hierarchical relationship;

[0019] The server cluster includes:

[0020] an acquiring unit, configured to acquire an information acquisition request, wherein the information acquisition request is used to request information about a target resource, and the information acquisition request includes an identifier of a target user;

[0021] A first determining unit, configured to determine M resource groups corresponding to the identifier of the target user, where M is a positive integer greater than or equal to 1;

[0022] a second determining unit, configured to determine N nodes based on the M resource groups, where the N nodes include one or more nodes corresponding to each of the M resource groups, where N is a positive integer greater than or equal to 1, and the server cluster includes the N nodes;

[0023] A third determining unit is configured to determine a target node based on the N nodes, where the target node stores information about the target resource;

[0024] The output unit is used for the target node to output the information of the target resource.

[0025] In a fourth aspect, a server is provided, comprising:

[0026] a receiving unit, configured to receive original data sent by the cache server, where the original data includes an identifier of the first resource;

[0027] a data processing unit, configured to perform data processing on raw data corresponding to the identifier of the first resource in the raw data at at least one preset period based on the identifier of the first resource to obtain at least one information of the first resource;

[0028] a determining unit, configured to determine, based on the identifier of the first resource, an identifier of a first node corresponding to the identifier of the first resource;

[0029] A sending unit is configured to send the at least one information to the first node corresponding to the identifier of the first node and all parent nodes of the first node.

[0030] According to a fifth aspect, an electronic device is provided, including:

[0031] a processor adapted to execute a computer program;

[0032] A computer-readable storage medium stores a computer program, and when the computer program is executed by the processor, the method of the first aspect or the method of the second aspect is implemented.

[0033] In a sixth aspect, a computer-readable storage medium is provided for storing a computer program, wherein the computer program enables a computer to execute the method of the first aspect or the method of the second aspect.

[0034] In a seventh aspect, a computer program product is provided, comprising a computer program / instruction, which, when executed by a processor, implements the method of the first aspect or the method of the second aspect.

[0035] Based on the above scheme, first, this application determines M resource groups corresponding to the identifier of the target user, which is equivalent to taking into account the permissions of the resource groups accessible to the target user; secondly, it determines N nodes corresponding to the M resource groups, which is equivalent to taking into account that the resources in the resource groups accessible to the target user are related to the N nodes; finally, based on the N nodes, it determines the target node, which enables the target user to jump directly from the root node to the only target node when accessing the top-level node (root node) among multiple nodes with a hierarchical relationship. Since the target node stores the information of the target resource, the target resource information is directly output by the target node, so that when obtaining the target resource information from multiple nodes with a hierarchical relationship, it is no longer all obtained from the root node, but the pressure of the root node to query the target resource information is shared through the target node. Moreover, the target node has less data than the root node. Outputting the target resource information at the target node improves the query efficiency of the target resource information, that is, improves the efficiency of the user in obtaining the target resource information.

[0036] That is, by determining the M resource groups corresponding to the target user's identifier and the N nodes corresponding to the M resource groups, and then determining the target node based on the N nodes, the user can jump directly from the root node to the target node when accessing the root node among multiple nodes, thereby improving the output efficiency of the target resource information.

[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] With the research and advancement of artificial intelligence technology, artificial intelligence technology has been studied and applied in many fields, such as common smart homes, smart wearable devices, virtual assistants, smart speakers, smart marketing, unmanned driving, autonomous driving, drones, robots, smart medical care, smart customer service, etc. It is believed that with the development of technology, artificial intelligence technology will be applied in more fields and play an increasingly important role.

[0051] The solutions provided in the embodiments of the present application also relate to data processing technologies in the field of network media. Network media works differently from traditional audio and video equipment. Network media relies on technologies and equipment provided by information technology (IT) equipment developers to transmit, store, and process audio and video signals. Traditional serial digital input (SDI) transmission methods lack true network switching characteristics. A lot of work needs to be done to use SDI to create some network functions similar to those provided by Ethernet and Internet Protocol (IP). Therefore, network media technology in the video industry has emerged. Furthermore, data processing technology for network media may include the transmission, storage, and processing of audio and video signals.

[0052] Figure 1 This is an example of the system framework 100 provided in an embodiment of the present application.

[0053] The system framework 100 can be an information query system. The specific type of information is not limited in this embodiment of the present application. The system framework 100 includes: a server cluster 110, a cache server 120, and a first server 130. Both the cache server 120 and the first server 130 can be connected to the server cluster 110 via a wireless or wired network.

[0054] Cache server 120 and first server 130 can each be at least one of a single server, multiple servers, a cloud computing platform, and a virtualization center. Cache server 120 is configured to receive raw data from server cluster 110 and send the received raw data to first server 130. First server 130 processes the received raw data to obtain processed data and sends the processed data to server cluster 110.

[0055] The server cluster 110 may include at least one of a plurality of servers, a cloud computing platform, and a virtualization center. The server cluster 110 includes a plurality of nodes in a hierarchical relationship, wherein each node may be one or more servers; on the one hand, the server cluster 110 is responsible for acquiring and storing raw data; on the other hand, the server cluster 110 is responsible for receiving and storing processed data. Optionally, the server cluster 110 may also undertake secondary data processing tasks, while the first server 130 undertakes primary data processing tasks; optionally, the cache server 120 may also undertake secondary data processing tasks, while the first server 130 undertakes primary data processing tasks; alternatively, the cache server 120, the first server 130, and the server cluster 110 may adopt a distributed computing architecture for collaborative computing.

[0056] Optionally, taking the system framework 100 as a monitoring resource report query system as an example, the server cluster 110 includes: a master node 111, an agent node 112, and an agent node 113. The master node 111, the agent node 112, and the agent node 113 can be servers, respectively, and the master node 111 is the parent node of the agent node 112 and the agent node 113. Exemplarily, the master node 111, the agent node 112, and the agent node 113 are respectively used to obtain monitoring data of different resources in their respective nodes, and uniformly send the obtained monitoring data to the cache server 120. The cache server 120 sends the received monitoring data to the first server 130. The first server 130 processes the received monitoring data to obtain processed data, and then sends the processed data to at least one of the master node 111, the agent node 112, and the agent node 113 in the server cluster 110 according to certain rules.

[0057] It should be noted that the number of nodes in the server cluster 110 is only illustrative and may also include multiple other proxy nodes, which is not specifically limited in this application.

[0058] Figure 2 2 is a schematic flow chart of an information acquisition method 200 provided in an embodiment of the present application. The method 200 is applied to a server cluster, which includes multiple nodes in a hierarchical relationship; for example Figure 1 A server cluster 110 is shown.

[0059] like Figure 2 As shown, the method 200 may include some or all of the following:

[0060] S201, obtaining an information acquisition request, where the information acquisition request is used to request information about a target resource, and the information acquisition request includes an identifier of a target user;

[0061] S202, determining M resource groups corresponding to the identifier of the target user, where M is a positive integer greater than or equal to 1;

[0062] S203: Determine N nodes based on the M resource groups, where the N nodes include one or more nodes corresponding to each of the M resource groups, where N is a positive integer greater than or equal to 1, and the server cluster includes the N nodes.

[0063] S204, determining a target node based on the N nodes, where the target node stores information about the target resource;

[0064] S205: The target node outputs the information of the target resource.

[0065] In other words, first, the server cluster obtains an information acquisition request, requesting to obtain information about the target resource, and the information acquisition request includes the identifier of the target user; secondly, the server cluster determines M resource groups corresponding to the identifier of the target user based on the identifier of the target user, and then for each of the M resource groups, determines one or more nodes corresponding to each resource group, and finally determines N nodes, and then determines the target node based on the N nodes; finally, the target node outputs the information about the target resource.

[0066] For example, first, the server cluster obtains an information acquisition request through the master node, requesting to obtain information about the target resource, and the information acquisition request includes the identifier of the target user; secondly, the master node determines M resource groups corresponding to the identifier of the user based on the identifier of the target user, and then for each of the M resource groups, determines one or more proxy nodes corresponding to each resource group, and finally determines N proxy nodes corresponding to the M resource groups, and determines the target node based on the N proxy nodes; finally, the server cluster outputs the information about the target resource through the target node. For example, the master node can be as follows Figure 1 The master node 111 shown, the N nodes can be as follows Figure 1 As shown in the example, the proxy node 112 and the proxy node 113 are used, and the target node is the master node 111 .

[0067] Exemplarily, the information may be a statistical report of monitoring data, or large-screen display information of monitoring data; for example, the large-screen display information may be the ranking of a certain indicator in the monitoring data, or the average data of a certain indicator.

[0068] Another example is that the information can be a statistical report of order data, or it can be a large-screen display information of order data; for example, the large-screen display information can be a ranking of different order categories, or it can be the average data of a certain type of order. This application does not impose specific restrictions on this.

[0069] Of course, in other alternative embodiments, if the information of the target resource is the original data of the target resource, the server cluster may directly determine the node corresponding to the target resource among the N nodes as the target node.

[0070] Based on the above scheme, first, this application determines M resource groups corresponding to the identifier of the target user, which is equivalent to taking into account the permissions of the resource groups accessible to the target user; secondly, it determines N nodes corresponding to the M resource groups, which is equivalent to taking into account that the resources in the resource groups accessible to the target user are related to the N nodes; finally, based on the N nodes, it determines the target node, which enables the target user to jump directly from the root node to the only target node when accessing the top-level node (root node) among multiple nodes with a hierarchical relationship. Since the target node stores the information of the target resource, the target resource information is directly output by the target node, so that when obtaining the target resource information from multiple nodes with a hierarchical relationship, it is no longer all obtained from the root node, but the pressure of the root node to query the target resource information is shared through the target node. Moreover, the target node has less data than the root node. Outputting the target resource information at the target node improves the query efficiency of the target resource information, that is, improves the efficiency of the user in obtaining the target resource information.

[0071] That is, by determining the M resource groups corresponding to the target user's identifier and the N nodes corresponding to the M resource groups, and then determining the target node based on the N nodes, the user can jump directly from the root node to the target node when accessing the root node among multiple nodes, thereby improving the output efficiency of the target resource information.

[0072] It should be noted that the hierarchical relationship may be a tree-structured hierarchical relationship, wherein the information acquisition request may be obtained through a root node in the server cluster.

[0073] It should be noted that the target resource is one or more resources accessible to the target user.

[0074] It should be noted that the node corresponding to each resource group in the M resource groups can be configured with one or more resources, and the M resource groups are resource groups corresponding to resources accessible to the target user;

[0075] The following will be combined Figure 3 and Figure 4 The process of outputting target resource information by the target node is described with an example.

[0076] Figure 3 This is an exemplary block diagram 300 of multiple nodes in a two-layer hierarchical relationship provided by an embodiment of the present application.

[0077] like Figure 3As shown, the block diagram 300 includes a node 310 , a node 320 , a node 330 and a node 340 ; wherein the node 310 is the parent node of the nodes 320 , 330 and 340 .

[0078] Node 320 is associated with the Beijing resource group, node 330 is associated with the Hangzhou resource group, and node 340 is associated with the Dalian resource group. Node 310 is responsible for monitoring resources E and F, node 320 is responsible for monitoring resources A and B, node 330 is responsible for monitoring resource C, and node 340 is responsible for monitoring resource D. User A is associated with the Beijing resource group, user B is associated with the Hangzhou resource group, and user C is associated with both the Beijing and Dalian resource groups.

[0079] Based on this, if node 310 receives an information acquisition request from user A, it first detects that the resource group associated with user A is the Beijing resource group; secondly, based on the Beijing resource group, it determines that node 320 is associated with the Beijing resource group; finally, node 310 passes the information acquisition request to node 320 and obtains the information of the target resource from node 320.

[0080] Since in the existing solution, nodes 320, 330 and 340 will send the acquired monitoring resource data to node 310, the amount of data of node 310 is much larger than that of node 320. Therefore, in the solution provided in this application, Figure 3 In the block diagram 300 shown, the user can directly view the information of the target resource at the node 320 , which not only improves the query efficiency but also relieves the query pressure of the node 310 .

[0081] If node 310 receives an information acquisition request from user C, first, it detects that the resource groups associated with user C are the Beijing resource group and the Dalian resource group; secondly, based on the Beijing resource group and the Dalian resource group, it determines that nodes 320 and 340 are associated with the Beijing resource group and the Dalian resource group respectively, and determines the target node in the parent node 310 of nodes 320 and 340, that is, the target node is node 310. Since the target node and the node of the information acquisition request are the same node, the information of the target resource is directly obtained from node 310 of the information acquisition request.

[0082] Figure 4 This is an exemplary block diagram 400 of multiple nodes in a three-layer hierarchical relationship provided by an embodiment of the present application.

[0083] like Figure 4As shown, the block diagram 400 includes node 410, node 420, node 430, node 440, node 450, node 460, node 470, node 480 and node 490; wherein, the node 410 is the parent node of node 420, node 430, node 440, node 450, node 460, node 470, node 480 and node 490; node 420 is the parent node of node 450, node 460 and node 470; node 440 is the parent node of node 480 and node 490.

[0084] Node 420 is associated with the Beijing resource group, node 430 is associated with the Hangzhou resource group, node 440 is associated with the Dalian resource group, node 450 is associated with the Xicheng District resource group, nodes 460 and 470 are associated with the Haidian District resource group, and nodes 480 and 490 are associated with the High-tech Zone resource group. Node 420 is responsible for monitoring resource D, node 430 is responsible for monitoring resource E, node 440 is responsible for monitoring resource H, node 450 is responsible for monitoring resource A, node 460 is responsible for monitoring resource B, node 470 is responsible for monitoring resource C, node 480 is responsible for monitoring resource F, and node 490 is responsible for monitoring resource G. User A is associated with the Beijing resource group, user B is associated with the Xicheng District resource group, and user C is associated with the Haidian District resource group and the Xicheng District resource group.

[0085] Based on this, if node 410 receives an information acquisition request from user A, it first detects that the resource group associated with user A is the Beijing resource group; secondly, based on the Beijing resource group, it determines that node 420 is associated with the Beijing resource group; finally, node 410 passes the information acquisition request to node 420 and obtains the information of the target resource from node 420.

[0086] If node 410 receives an information acquisition request from user B, it first detects that the resource group associated with user B is the Xicheng District resource group; secondly, based on the Xicheng District resource group, it determines that node 450 is associated with the Xicheng District resource group; finally, node 410 passes the information acquisition request to node 450 and obtains the information of the target resource from node 450.

[0087] If node 410 receives an information acquisition request from user C, first, it detects that the resource groups associated with user C are the Haidian District resource group and the Xicheng District resource group; second, based on the Haidian District resource group and the Xicheng District resource group, it determines that nodes 450, 460, and 470 are associated with the Xicheng District resource group and the Haidian District resource group, respectively; finally, the target node is determined from the parent nodes of nodes 450, 460, and 470, that is, the target node is determined from nodes 420 and 410. For example, if the target node is determined to be 420, the information acquisition request is passed to node 420 to obtain the information of the target resource from node 420.

[0088] Since in the existing solution, nodes 420, 440 and 440 will send the acquired monitoring resource data to node 410, the amount of data of node 410 is much larger than that of node 420. Therefore, in the solution provided in this application, Figure 4 In the block diagram 400 shown, the user can directly view the information of the target resource at the node 420 , which not only improves the query efficiency but also relieves the query pressure of the node 410 .

[0089] If node 410 receives an information acquisition request from user C, first, it detects that the resource groups associated with user C are the Beijing resource group and the Dalian resource group; secondly, based on the Beijing resource group and the Dalian resource group, it determines that nodes 420 and 440 are associated with the Beijing resource group and the Dalian resource group respectively, and determines the target node in the parent node 410 of nodes 420 and 440, that is, the target node is node 410. Since the target node and the node of the information acquisition request are the same node, the information of the target resource is directly obtained from node 410 of the information acquisition request.

[0090] In some embodiments of the present application, S202 may include:

[0091] Obtaining a first mapping relationship;

[0092] The first mapping relationship includes an identifier of at least one user and an identifier of a resource group corresponding to each identifier of the at least one user, and the identifier of the at least one user includes an identifier of the target user;

[0093] Determine the identifier of the resource group corresponding to the identifier of the target user in the first mapping relationship as the identifier of the M resource groups;

[0094] The resource groups corresponding to the identifiers of the M resource groups are determined as the M resource groups.

[0095] For example, the resource group can be divided by region, which can be Beijing resource group, Hangzhou resource group, Dalian resource group, etc. The user's identification can also be divided by region, which can be Beijing operation and maintenance 1, Hangzhou operation and maintenance 2, Dalian operation and maintenance 3, Northeast and North China operation and maintenance director 4, etc.

[0096] As another example, the resource groups may be divided by region, such as the Xicheng District resource group, the Haidian District resource group, the Chaoyang District resource group, etc. The user identifiers may also be divided by region, such as Xicheng District Operation and Maintenance 2, Haidian District Operation and Maintenance 3, Chaoyang District Operation and Maintenance 4, etc. Of course, resource groups may also be divided by combining regions and areas, and this application does not impose any specific restrictions on this.

[0097] Exemplarily, the first mapping relationship may be stored in the node in the form of a vocabulary file or in the form of a correspondence graph. The present application does not impose any specific restrictions on the storage method or storage format of the first mapping relationship.

[0098] In some embodiments of the present application, S203 may include:

[0099] Obtaining a second mapping relationship;

[0100] The second mapping relationship includes an identifier of at least one resource group and an identifier of a node corresponding to an identifier of each resource group in the identifier of the at least one resource group, and the at least one resource group includes the M resource groups;

[0101] For the identifier of the first resource group among the identifiers of the M resource groups respectively corresponding to the M resource groups, determine the identifier of the node corresponding to the identifier of the first resource group in the second mapping relationship as the identifier of the node among the identifiers of the N nodes respectively corresponding to the N nodes;

[0102] The N nodes corresponding to the identifiers of the N nodes are determined as the N nodes.

[0103] Illustratively, any one of the N nodes may be a server in a server cluster, or may be multiple servers in a server cluster, and this application does not impose any specific limitation on this.

[0104] Illustratively, the identifier of the node may be the server number or the server IP address, and this application does not impose any specific limitation on this.

[0105] Exemplarily, the second mapping relationship may be stored in the node in the form of a vocabulary file or in the form of a correspondence graph. The present application does not impose any specific restrictions on the storage method or storage format of the second mapping relationship.

[0106] It should be noted that any one of the N nodes is used to monitor one or more resources in the resource group corresponding to the any one node.

[0107] In some embodiments of the present application, S204 may include:

[0108] If N is greater than 1, then among the parent nodes corresponding to the N nodes, the common parent node of the N nodes is determined as the target node.

[0109] Determining the common parent node of the N nodes as the target node is equivalent to sharing the pressure of the node that obtains the information acquisition request to query the information of the target resource by sacrificing part of the storage space of the common parent node of the N nodes. Moreover, when the node that obtains the information acquisition request is the root node and the common parent node of the N nodes is not the root node, the amount of data of the common parent node of the N nodes is much smaller than the amount of data of the root node. Therefore, querying the information of the target resource in the common parent node of the N nodes can improve the query efficiency.

[0110] Of course, in other alternative embodiments, since the information of the target resource is stored in the common parent node of the N nodes, if the user directly queries the information of the target resource in the common parent node of the N nodes, there is no need to call the interfaces of the N nodes, and the information of the target resource can be directly obtained.

[0111] In some embodiments of the present application, if N is equal to 1, the N nodes are determined as the target nodes.

[0112] If N is equal to 1, which is equivalent to there being only one clear node among the N nodes, then a node among the N nodes is directly determined as the target node, which is equivalent to directly jumping from the node that obtains the information acquisition request to the target node, and querying and outputting the information of the target resource from the target node. On the one hand, it reduces the query pressure of the node that obtains the information acquisition request. On the other hand, since the amount of data of the target node is less than the amount of data of the node that obtains the information acquisition request, when querying the information of the target resource, it improves the query efficiency of the target resource information.

[0113] In some embodiments of the present application, the target resource includes resources monitored by the N nodes and / or resources monitored by all child nodes of the N nodes.

[0114] For example, Figure 4 As shown, since the resource group associated with user A is the Beijing resource group, user A can view the resources in the node corresponding to the Beijing resource group associated with user A, that is, the information of resource D can be viewed in node 420. Since nodes 450, 460 and 470 are respectively child nodes of node 420, the user can also access the information of the resources (resources A, B, C) monitored by nodes 450, 460 and 470 respectively.

[0115] For example, Figure 4As shown, since the resource groups associated with user C are the Xicheng District resource group and the Haidian District resource group, user C can view the resources (resource A, resource B) monitored by nodes 450 and 460 corresponding to the Xicheng District resource group and the Haidian District resource group associated with user C respectively. Since node 451 is a child node of node 450, user C can also view the information of resource I monitored by node 451. Since the target node is the parent node corresponding to the N nodes, when the target node is node 420, the information of resource A, resource B, and resource I can be viewed in node 420, but the information of resource D monitored by node 420 cannot be viewed.

[0116] In some embodiments of the present application, before S201, the method may further include:

[0117] Construct multiple nodes with hierarchical relationships;

[0118] Collecting and saving original data of a first resource through a first node among the multiple nodes, where the original data includes an identifier of the first resource;

[0119] Sending the original data to the cache server;

[0120] At least one piece of information about the first resource sent by the first server is received and stored through the first node and all parent nodes of the first node.

[0121] In other words, before obtaining an information acquisition request, the server cluster first constructs multiple nodes in a hierarchical relationship, collects and saves the original data of the first resource through the first node among the multiple nodes, and sends the original data to the cache server. The cache server and the first server process the original data to obtain at least one information of the first resource. The first server sends the at least one information of the first resource to the server cluster, and the first node in the server cluster and all parent nodes of the first node receive and save the at least one information of the first resource sent by the first server.

[0122] Exemplarily, after collecting and storing the raw data of the first resource, the first node outputs the raw data of the first resource to a cache server, Kafka, or a message middleware. The Kafka server or the message middleware then sends the raw data of the first resource to the first server, which processes the raw data of the first resource. For example, multiple nodes output the raw data of the resources corresponding to each node to the same category (Topic) of the same Kafka.

[0123] It should be noted that the first server can be an independently deployed server, which is used to uniformly consume the original data of resources corresponding to each node sent by Kafka.

[0124] It should be noted that Kafka is a high-throughput distributed publish-subscribe messaging system. Each message published to the Kafka cluster has a category, which is called a Topic. Generally, messages from different Topics are physically stored separately. Although the messages of a Topic are logically stored on one or more servers, users only need to specify the Topic of the message to produce or consume data without having to worry about where the data is stored.

[0125] It should be noted that the first node is any node among the multiple nodes.

[0126] It should be noted that the first resource is a resource corresponding to the first node in the pre-stored correspondence between nodes and resources.

[0127] It should be noted that if the user has access to a resource group, they can add new resources to the node corresponding to the resource group. This means that based on the pre-stored correspondence between the user's identifier and the resource group, and between the resource group and the node, the new resource is transferred to the node through the interface. Optionally, the new resource is transferred to the node through the Resource Representational State (REST) ​​interface.

[0128] It should be noted that the cache server and the first server can be independent physical servers, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, as well as big data and artificial intelligence platforms. The servers can be connected directly or indirectly through wired or wireless communications, and this application does not impose any restrictions here.

[0129] It should be noted that since all parent nodes include the root node among the multiple nodes, in other alternative embodiments, if the user accesses the root node, since the root node also stores the information of the target resource, the user can still ensure efficiency when viewing the information of the target resource.

[0130] By storing at least one information of the first resource in the first node and all parent nodes of the first node, on the one hand, if the user accesses the parent node, the information of the target resource can be directly obtained without calling the interface of the child node; on the other hand, compared with the existing solution in which the root node stores the processed data of all resources, the data volume of at least one information of the first resource occupies a limited storage space of the parent node, that is, on the basis of sacrificing a small part of the storage space of the parent node, efficient query of the information of the first resource is achieved, thereby improving the query efficiency.

[0131] In addition, on the one hand, the original data of the first resource is only saved in the corresponding node of the first resource and does not need to be reported to the root node, which can save the storage space of the root node; on the other hand, the user can directly view the original data of the target resource in the node where the original data of the target resource is stored, which improves the query efficiency compared to querying at the root node.

[0132] It should be noted that before constructing multiple nodes with a hierarchical relationship, the following corresponding relationship can be pre-stored in the root node:

[0133] The correspondence between pre-stored resource groups and nodes:

[0134] For example, the resource groups may include Beijing resource group, Hangzhou resource group, Dalian resource group, and other resource groups, and the nodes may include Figure 3 Node 320, node 330, and node 340 are shown; among them, the Beijing resource group corresponds to node 320, the Hangzhou resource group corresponds to node 330, and the Dalian resource group corresponds to node 340.

[0135] In another example, the resource groups may include Beijing resource group, Xicheng District resource group, Haidian District resource group, Chaoyang District resource group, and other resource groups, and the nodes may include: Figure 4 Nodes 420, 450, 460, and 470 are shown; among them, the Beijing resource group corresponds to node 420, the Xicheng District resource group corresponds to node 450, the Haidian District resource group corresponds to node 460, and the Chaoyang District resource group corresponds to node 470.

[0136] The correspondence between pre-stored resource groups and resources:

[0137] For example, resources A and B correspond to the Beijing resource group, resource C corresponds to the Hangzhou resource group, resource D corresponds to the Dalian resource group, resource E corresponds to other resource groups, and resource F has no corresponding resource group. Based on this, the corresponding relationship between pre-stored nodes and resources is:

[0138] Resources A and B correspond to node 320 , resource C corresponds to node 330 , resource D corresponds to node 340 , and resources E and F have no matching nodes, so they correspond to root node 310 .

[0139] In another example, resource D corresponds to the Beijing resource group, resource A corresponds to the Xicheng District resource group, resource B corresponds to the Haidian District resource group, and resource C corresponds to the Chaoyang District resource group. Based on this, the corresponding relationship between the pre-stored nodes and resources is:

[0140] Node 450 corresponds to resource A, node 460 corresponds to resource B, node 470 corresponds to resource C, and node 420 corresponds to resource D.

[0141] Pre-stored correspondence between users and resource groups:

[0142] For example, user A corresponds to the Beijing resource group, user B corresponds to the Hangzhou resource group, and user C corresponds to the Dalian resource group.

[0143] In another example, user A corresponds to the Beijing resource group, user B corresponds to the Xicheng District resource group, and user C corresponds to the Haidian District resource group and the Chaoyang District resource group.

[0144] It should be noted that the administrator user can view all resources in multiple nodes, that is, the resource group corresponding to the administrator user is all resource groups.

[0145] In some embodiments of the present application, the multiple nodes having a hierarchical relationship may be constructed in the following manner:

[0146] Obtain a configuration file for each of the multiple nodes;

[0147] The multiple nodes are constructed based on the configuration file of each node.

[0148] Exemplarily, multiple nodes are registered according to their respective node configuration files when they are first started, thereby forming multiple nodes with a hierarchical relationship. When the multiple nodes are subsequently run, they perform corresponding functions according to the registration information in the configuration files.

[0149] It should be noted that the format of the configuration file of each node is the same.

[0150] By assigning a configuration file to each node, it is equivalent to expanding the functions of the child nodes. The child nodes no longer just monitor the raw data of resources, but like the root node, have all the functions of a complete node, sharing the storage and query pressure of the root node, reducing the data storage volume of the root node, and improving data query efficiency.

[0151] For example, Figure 3 As shown, there are node 310 , node 320 , node 330 , and node 340 .

[0152] For the node 310, node 320, node 330 and node 340, when deployed, node 310 is the root node, the identifier of node 310 can be ADMIN, and the identifier of the parent node of node 320, node 330 and node 340 is ADMIN. Then, during the first startup process, each node will register according to the configuration file of its own node, thereby forming the following: Figure 3 The four nodes shown have a hierarchical relationship.

[0153] Another exemplary example is Figure 4As shown, the identifier of node 420 may be BEIJING, and the identifier of the parent node of node 420 is ADMIN; the identifiers of node 450, node 460, and node 470 are XICHENG, HAIDIAN, and CHAOYANG, respectively, and the identifier of the parent node of node 450, node 460, and node 470 is BEIJING. In the first startup process, each node will register according to its own node configuration file, thereby forming the following Figure 4 Multiple nodes with a hierarchical relationship are shown.

[0154] Each node is configured at the first startup through its configuration file, so that subordinate relationships can be quickly established between nodes, thereby realizing multiple nodes with a hierarchical relationship.

[0155] In some embodiments of the present application, the configuration file includes at least one of the following:

[0156] The node identifier of the node, the Internet Protocol IP address of the node, the service port of the node, the node identifier of the node's parent node, the Internet Protocol IP address of the node's parent node, and the service port of the node's parent node.

[0157] It should be noted that the communication between the node and the parent node of the node is achieved based on the Internet Protocol IP address of the node, the service port of the node, the Internet Protocol IP address of the parent node of the node and the service port of the parent node of the node, that is, the IP address and service port are mainly used for REST interface calls between nodes.

[0158] In some embodiments of the present application, the first node collects and stores the original data of the first resource in the following manner, including:

[0159] Obtaining a third mapping relationship;

[0160] The third mapping relationship includes identifiers of multiple nodes and identifiers of resources corresponding to the identifiers of each of the multiple nodes, and the identifiers of the multiple nodes include the identifier of the first node;

[0161] Determine the identifier of the resource corresponding to the identifier of the first node in the third mapping relationship as the identifier of the first resource;

[0162] The original data of the first resource corresponding to the identifier of the first resource is collected and stored through the first node.

[0163] Exemplarily, the third mapping relationship may be stored in the node in the form of a vocabulary file or in the form of a correspondence graph. The present application does not impose any specific restrictions on the storage method or storage format of the third mapping relationship.

[0164] The following will be combined Figure 5a and Figure 5b The overall process of the information acquisition method provided in the embodiment of the present application is schematically described.

[0165] Figure 5a This is an example of the process of pre-storing the corresponding relationship in the master node provided by an embodiment of the present application.

[0166] like Figure 5a As shown, first, the administrator logs in to the master node, creates a common user on the master node, and creates a resource group on the master node; second, the administrator associates the common user with the resource group on the master node, and associates the resource group with the nodes in the server cluster; finally, the common user adds resources to the resource group associated with it, and the resource group distributes the added resources to the proxy nodes associated with the resource group.

[0167] exist Figure 5a On the basis of Figure 5b This is an example of a process in which a user accesses a server cluster to obtain information about a target resource, as provided in an embodiment of the present application.

[0168] like Figure 5b As shown, after an ordinary user logs in to the master node in the server cluster, the master node can Figure 5a The resource group associated with the ordinary user and the proxy node in the server cluster associated with the resource group will jump from the master node to the proxy node, thereby obtaining the target resource information at the proxy node.

[0169] Figure 6 is another schematic flow chart of the information acquisition method 600 provided in an embodiment of the present application. The method 600 is applied to a first server, which may be Figure 1 A first server 130 is shown.

[0170] It should be noted that the first server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, as well as big data and artificial intelligence platforms. The servers can be connected directly or indirectly through wired or wireless communications, and this application does not impose any restrictions here.

[0171] like Figure 6 As shown, the method 600 may include some or all of the following:

[0172] S601, receiving original data sent by a cache server, where the original data includes an identifier of a first resource;

[0173] S602, based on the identifier of the first resource, performing data processing on raw data corresponding to the identifier of the first resource in at least one preset period to obtain at least one information of the first resource;

[0174] S603, based on the identifier of the first resource, determining an identifier of a first node corresponding to the identifier of the first resource;

[0175] S604: Send the at least one information to the first node corresponding to the identifier of the first node and all parent nodes of the first node.

[0176] In other words, after the first server receives the original data sent by the cache server, it processes the original data corresponding to the identifier of the first resource in at least one preset period, obtains at least one information about the first resource, and sends the at least one information to the first node that monitors the original data of the first resource in the server cluster and all parent nodes of the first node.

[0177] For example, Figure 3 As shown, if the first node is node 320 , the at least one information will be sent to node 320 and node 310 .

[0178] Exemplarily, the at least one information may be the average value of a statistical report of monitoring data within a preset period, or it may be the large-screen display information of monitoring data within a preset period; for example, the statistical report may be the average value of the monitoring data; for example, the large-screen display information may be the ranking of a certain indicator in the monitoring data, or it may be the average data of a certain indicator.

[0179] Of course, the at least one information may also be a statistical report of monitoring data under multiple preset periods, or may be a large-screen display information of monitoring data under multiple preset periods;

[0180] Another exemplary embodiment is that the at least one information may be a statistical report of order data within a preset period, or it may be large-screen display information of order data within a preset period; for example, the large-screen display information may be a ranking of different order categories, or it may be the average data of a certain type of order, and this application does not impose any specific restrictions on this.

[0181] Of course, the at least one information may also be a statistical report of order data under multiple preset periods, or may be large-screen display information of order data under multiple preset periods.

[0182] It should be noted that the original data includes original data of one or more resources, and the one or more resources include the first resource.

[0183] It should be noted that the at least one preset period can be one hour, one day, one week, half a month or one month, etc. This application does not impose any specific restrictions on the setting time of the at least one preset period.

[0184] It should be noted that the first node and all parent nodes of the first node are nodes in the server cluster.

[0185] By receiving the original data sent by the cache server, processing the original data, and then sending the processed data to the server cluster, on the one hand, while ensuring that users can obtain information about target resources in the server cluster, it not only reduces the computing power requirements of the devices in the server cluster, reduces the cost of the devices in the server cluster, but also reduces the load on the devices in the server cluster; on the other hand, handing over data processing to the first server can also improve the utilization rate of the computing power in the first server.

[0186] The following will be combined Figure 7 An example of a first server sending at least one information to a server cluster is given.

[0187] Figure 7 This is a schematic block diagram 700 of a first server sending at least one information to a server cluster provided by an embodiment of the present application.

[0188] like Figure 7 As shown, the block diagram includes all parent nodes 710 of the first node, the first node 720 , a cache server 730 and a first server 740 .

[0189] First, the first node 720 is used to store the acquired original data of the first resource into a local database, and send the original data of the first resource to a cache server.

[0190] The cache server 720 is configured to receive the original data of the first resource sent by the first node 720 , and send the original data of the first resource to the first server 730 .

[0191] The first server 730 is used to consume the original data of the first resource sent by the cache server 720, process the original data of the first resource in at least one preset period, obtain at least one information, and send the at least one information to the first node 720 and all parent nodes 710 of the first node.

[0192] It should be noted that the at least one cycle includes hourly, daily, weekly, and monthly.

[0193] In some embodiments of the present application, the at least one preset period includes a first preset period, a second preset period, a third preset period, and a fourth preset period, the first preset period is smaller than the second preset period, the second preset period is smaller than the third preset period, and the third preset period is smaller than the fourth preset period; based on this, S602 may include:

[0194] Processing original data corresponding to the identifier of the first resource at the first preset period to obtain first information;

[0195] performing data processing on the plurality of first information respectively obtained in the plurality of first preset periods in the second preset period to obtain second information;

[0196] performing data processing on the plurality of second information respectively obtained in the plurality of second preset periods in the third preset period to obtain third information;

[0197] performing data processing on the plurality of third information respectively obtained in the plurality of third preset periods in the fourth preset period to obtain fourth information;

[0198] determining the first information, the second information, the third information, and the fourth information as the at least one information;

[0199] Based on this, S604 may include:

[0200] The first information, the second information, the third information, and the fourth information are sent to the first node and all parent nodes of the first node.

[0201] Exemplarily, the first preset period, the second preset period, the third preset period, and the fourth preset period may be one hour, one day, one week, and one month, respectively.

[0202] By processing the data based on the results of a small preset period and then calculating the data processing results of a large period, the computational complexity is reduced and computing resources are saved.

[0203] In some embodiments of the present application, S602 may further include:

[0204] After sending the first information to the first node and all parent nodes of the first node, deleting original data corresponding to the identifier of the first resource;

[0205] After sending the second information to the first node and all parent nodes of the first node, deleting the first information;

[0206] After sending the third information to the first node and all parent nodes of the first node, deleting the second information;

[0207] After sending the fourth information to the first node and all parent nodes of the first node, the third information is deleted.

[0208] After sending the result of the data processing in the small cycle, the source data processed in the small cycle is deleted, which is equivalent to saving the storage space of the first server while ensuring the integrity of the data sent to the server cluster.

[0209] It should be noted that the terms "root node" and "master node" can be used interchangeably in this application.

[0210] It should be noted that the terms "sub-node" and "proxy node" are used interchangeably in this application.

[0211] It should be noted that in the above description, the terms "first\second\third" involved are only used to distinguish similar objects and do not represent a specific order for the objects. It should be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted and should not be a limitation of this application.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
