Description

Technical Field

[0001] The present application relates to the field of computer technology, specifically to the field of business scheduling technology, and in particular to a method and device for displaying information. Background Art

[0002] At present, the load balancing products of various manufacturers provide multiple scheduling algorithms such as weighted polling and weighted source IP, but they do not provide the distribution of business traffic on each backend server after scheduling. Therefore, which scheduling algorithm is most suitable for what business scenario depends entirely on the customer's technical staff's understanding of their own business situation and the load balancing scheduling algorithm mechanism.

[0003] For example, in a WeChat applet business, when a customer accesses the WeChat applet, it first passes through three nginx WEB servers. After the nginx proxy replaces the source IP, it forwards the business traffic to the load balancing product, and the load balancing product distributes the business traffic to two backend servers. The customer's technicians did not understand the scheduling algorithm mechanism of the load balancing and chose the "weighted source IP" scheduling algorithm. As a result, when the business system had problems one month later, they found that all business accesses were scheduled to the same backend server, causing the backend server to be overloaded and affecting the generation of business.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Figure 1 An exemplary system architecture 100 is shown to which an embodiment of the method of displaying information of the present application may be applied.

[0030] like Figure 1As shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104 and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0031] The terminal devices 101, 102, 103 interact with the server 105 via the network 104 to receive or send messages, etc. Various communication client applications, such as display applications, communication applications, etc., may be installed on the terminal devices 101, 102, 103.

[0032] Terminal devices 101, 102, 103 can be hardware or software. When terminal devices 101, 102, 103 are hardware, they can be various electronic devices with display screens, including but not limited to mobile phones and laptops. When terminal devices 101, 102, 103 are software, they can be installed in the electronic devices listed above. They can be implemented as multiple software or software modules (for example, services for providing display information), or they can be implemented as a single software or software module. No specific limitation is made here.

[0033] Server 105 may be a server that provides various services. For example, in response to receiving an access request, it obtains load information of each mounted backend server, and the backend server is used to process the access request; the load information is displayed for the user to determine the scheduling algorithm.

[0034] It should be noted that the server 105 can be hardware or software. When the server 105 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules (for example, a service for providing display information), or it can be implemented as a single software or software module. No specific limitation is made here.

Accordingly, the various parts (such as various units, sub-units, modules, sub-modules) included in the device for displaying information may be all arranged in the server 105, or all arranged in the terminal devices 101, 102, 103, or respectively arranged in the server 105 and the terminal devices 101, 102, 103.

[0036] It should be understood that Figure 1The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.

[0037] Figure 2 A flowchart 200 of a method for displaying information that can be applied to the present application is shown. In this embodiment, the method for displaying information includes the following steps:

[0038] Step 201, in response to obtaining an access request, obtain load information of each mounted backend server.

[0039] In this embodiment, the execution subject (such as Figure 1 The server 105 or terminal devices 101, 102, 103 shown in the figure can monitor the access request of the client in real time, and in response to monitoring the access request of the client, obtain the load information of each back-end server in at least one back-end server currently or historically mounted.

[0040] The load status information is used to indicate business data such as the traffic volume and request number processed by the backend server.

[0041] Here, the load condition information may be the load condition information at the current moment, or the load condition information of a historical statistical period, and this application does not limit this.

[0042] It should be pointed out that, here, the execution subject can obtain the load information of each backend server from the local monitoring device.

[0043] The monitoring device is used to record the load information of each mounted backend server.

[0044] In some optional methods, the load situation information includes at least one of the following: processing traffic size, query rate per second (QPS), and number of concurrent connections.

[0045] In this implementation, the execution subject obtains the load information of each mounted backend server, and the load information may include at least one of the above items.

[0046] Among them, the processed traffic size can be used to indicate the total traffic processed by the backend server in the historical preset statistical period from the current moment, and can also be used to indicate the total traffic processed by the backend server in the historical preset statistical period closest to the current moment, in bytes.

[0047] The query rate per second (QPS) can be used to indicate the QPS of the backend server in a historical preset statistical period from the current moment, and can also be used to indicate the number of requests per second of the backend server in a historical preset statistical period closest to the current moment. QPS = total number of requests in the statistical period / statistical period.

[0048] The number of concurrent connections can be used to indicate the number of concurrent connections of the backend server at the current moment, or it can be used to indicate the number of concurrent connections of the backend server at the end time of a historical preset statistical period closest to the current moment, that is, the number of all TCP connections in the ESTABLISHED state.

[0049] Among them, the historical preset statistical period can be set according to experience and actual needs, for example, 30s, 40s, etc., and this application does not limit this.

[0050] It should be noted that only when the access request is http / https, the load information includes the query rate per second (QPS).

[0051] Specifically, in response to obtaining an access request, such as an http access request, the execution subject can obtain the load information of the two mounted backend servers, such as backend server A and backend server B, from the local monitoring device, wherein the load information includes the processing flow size, QPS and the number of concurrent connections, wherein the processing flow size is used to indicate the total flow number processed by the backend server in the statistical period closest to the current moment, QPS is used to indicate the number of requests per second in the statistical period closest to the current moment, and the number of concurrent connections is used to indicate the number of concurrent connections of the backend server at the end time of the statistical period closest to the current moment. Here, the statistical period can be 30s. The load information of the backend server A can be expressed as [backend server A, processing flow size], [backend server A, QPS], [backend server A, concurrent connections]; the load information of the backend server B can be expressed as [backend server B, processing flow size], [backend server B, QPS], [backend server B, concurrent connections].

[0052] This implementation method obtains the load information of each backend server, and the load information includes at least one of the following: processing traffic size, QPS, and number of concurrent connections. The load information is displayed for users to determine the scheduling algorithm, so that users can optimize the deployment based on various indicators, effectively improving the effectiveness of deployment optimization.

[0053] In some optional methods, the load information of each mounted backend server is obtained, including: collecting statistics on the distribution of historical access requests in each backend server to obtain statistical results; and determining the load information of each backend server based on the statistical results.

[0054] In this implementation method, after the execution entity obtains the access request sent by the client within the historical preset statistical period, that is, obtains the historical access request, it can allocate the access request to one of the at least one currently mounted backend servers according to the preset scheduling algorithm, and record the allocation result.

[0055] The execution subject counts the distribution results of the access requests in each back-end server within a preset statistical period, obtains the statistical results, and further determines the load situation information of each back-end server based on the statistical results.

[0056] Specifically, within a historical preset statistical period closest to the current moment, for example, 30 seconds, after obtaining the access request sent by the client (corresponding to the business traffic of X bytes), the execution subject can distribute the access request to the currently mounted backend server, for example, backend server A and backend server B, according to the preset scheduling algorithm, and then determine whether the access request is an http / https access. If so, the recorded processed traffic number of backend server A is increased by X bytes, and the recorded processed request number of backend server A is increased by 1. If the access request is not an http / https access, for example, a TCP (Transmission Control Protocol) access, the recorded processed traffic number of backend server A is increased by X bytes. The number of processed requests and the size of processed traffic of backend server B remain unchanged. Finally, the execution subject can count the load information of backend server A and backend server B within 30 seconds, for example, the size of processed traffic and QPS.

[0057] This implementation method obtains statistical results by counting the distribution of historical access requests in each back-end server; determines the load information of each back-end server based on the statistical results, and then displays the load information of each back-end server. This realizes the determination of load information based on the statistical results of local records, avoids the limitations caused by obtaining load information from each back-end server, and improves the flexibility of obtaining load information.

[0058] In some optional embodiments, the method further includes: in response to detecting a newly mounted backend server, setting the processing traffic size of the newly mounted backend server to zero bytes.

[0059] In this implementation, the load status information includes the processing traffic size, and the execution entity can detect in real time whether there is a newly mounted backend server. If a newly mounted backend server is detected, the processing traffic size corresponding to the newly mounted backend server is set to zero bytes.

[0060] In addition, if the execution subject detects an unmounted backend server, the execution subject may delete the processing flow size and related records of the unmounted backend server.

[0061] Furthermore, before deleting the processing traffic size and related records of the unmounted backend server, the execution entity can save the processing traffic size up to the current moment so that when an access request is received later, the processing traffic size and related records of the unmounted backend server can be displayed to the user.

[0062] This implementation helps to improve the accuracy and reliability of processing traffic size statistics by setting the processing traffic size of the newly mounted backend server to zero bytes in response to detecting the newly mounted backend server.

[0063] In some optional embodiments, the method further includes: in response to detecting a newly mounted backend server, setting a query rate per second (QPS) of the newly mounted backend server to zero.

[0064] In this implementation, the load status information includes QPS, and the execution subject can detect in real time whether there is a newly mounted backend server. If a newly mounted backend server is detected, the QPS corresponding to the newly mounted backend server is set to zero.

[0065] In addition, if the execution subject detects an unmounted backend server, the execution subject may delete the QPS and related records of the unmounted backend server.

[0066] Furthermore, before deleting the QPS and related records of the unmounted backend server, the execution subject may save the QPS up to the current moment so that when an access request is subsequently obtained, the QPS and related records of the unmounted backend server can be displayed to the user.

[0067] This implementation helps to improve the accuracy and reliability of QPS statistics by setting the QPS of the newly mounted backend server to zero in response to detecting the newly mounted backend server.

[0068] Step 202: Display the load situation information for the user to determine the scheduling algorithm.

[0069] In this embodiment, after obtaining the load information of each back-end server, the execution entity may use information presentation methods in existing technologies or future development technologies, such as API (Application Program Interface) interface calls, console visualization displays, etc., for display. This application does not limit this, so that users can determine the scheduling algorithm based on their own business scenarios.

[0070] The scheduling algorithm is used to instruct the load balancing device to follow the forwarding rules when forwarding the received business traffic to the backend server cluster.

[0071] Continue to see Figure 3 , Figure 3 It is a schematic diagram of an application scenario of the method for displaying information according to this embodiment.

[0072] exist Figure 3 In the application scenario, the execution subject 301 is mounted with a backend server cluster, and the backend server cluster includes: backend server E302, backend server F303, and backend server G304. Among them, the backend server is used to process access requests. In response to the access request sent by the client, the execution subject obtains the load information of each mounted backend server locally. Here, the load information can be the load information of each backend server in the most recent historical preset statistical period from the current moment, for example, [backend server E, load information 1] 305, [backend server F, load information 2] 306, [backend server G, load information 3] 307. After obtaining the load information of each backend server, the execution subject can display the load information of each backend server 308, so that the user can determine the scheduling algorithm in combination with its own business scenario.

[0073] The method for displaying information disclosed in the present invention obtains the load information of each mounted back-end server in response to an access request, and the back-end server is used to process the access request; the load information is displayed for the user to determine the scheduling algorithm, which effectively avoids the impact of excessive load on the back-end server on the generated business, and helps the user to make timely adjustments to the scheduling algorithm or optimize the business deployment.

[0074] Further references Figure 4 , which shows a process 400 of another embodiment of a method for displaying information. In this embodiment, the process 400 of the method for displaying information of this embodiment may include the following steps:

[0075] Step 401, in response to obtaining an access request, obtain the load information of each currently mounted backend server.

[0076] In this embodiment, the implementation details and technical effects of step 401 can refer to the description of step 201 and will not be repeated here.

[0077] Step 402: Display the load situation information for the user to determine the scheduling algorithm.

[0078] In this embodiment, the implementation details and technical effects of step 402 can refer to the description of step 202 and will not be repeated here.

[0079] Step 403: In response to determining that the load condition information satisfies a preset alarm condition, output alarm information.

[0080] In this embodiment, after obtaining the load condition information, the execution subject can determine whether the load condition information matches the preset alarm condition. If the load condition information meets the preset alarm condition, the alarm information is output to prompt the user to adjust the scheduling algorithm in time to optimize the deployment.

[0081] Among them, the alarm condition may be that one or more items in the load condition information exceed a preset load threshold range, or one or more items in the load condition information are greater than or equal to a preset load threshold, which is not limited in this application.

[0082] Among them, the preset load threshold range and the preset load threshold can be determined based on experience and specific application scenarios, and this application does not limit this.

[0083] Specifically, the load threshold can be set by the user according to his or her specific business scenario.

[0084] Here, the alarm information can be output using information presentation methods in existing technologies or future development technologies, such as API (Application Program Interface) interface calls, console visualization displays, etc., and this application does not limit this.

[0085] The above embodiments of the present application, Figure 2 Compared with the corresponding embodiments, the process 400 of the method for displaying information in this embodiment reflects the output of alarm information in response to determining that the load condition information is greater than or equal to the corresponding load threshold, which helps users to obtain the overload condition information of each back-end server in time, and then optimize the business deployment in time to improve the optimization efficiency.
