Description

Technical Field

[0001] The present application relates to the technical field of big data analysis, and in particular to a method, device and equipment for determining flow control data. Background Art

[0002] In the operation of high-concurrency, cluster-deployed application systems, a large number of concurrent systems often makes it easy for small problems to have a big impact. For example, if an application system program has a problem, runs slowly, and causes blockage, this will not only lead to low efficiency of the entire system, but may even cause the system to crash. Therefore, how to determine the number of concurrent applications is becoming increasingly important.

[0003] In the prior art, the number of concurrent users of an application system is determined mainly by system operators checking each machine one by one. However, since large-scale application systems deployed in clusters often include dozens or even hundreds of machines, if system operators check each machine one by one, they will often miss the golden time for problem solving, thereby reducing system operation efficiency and affecting the business operation of the entire application system.

[0004] Therefore, the industry is in urgent need of a technical solution that can solve the above technical problems. Summary of the invention

[0021] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments in this specification, not all of the embodiments. Based on one or more embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the embodiments of this specification.

[0022] An implementation scheme provided in this specification can be applied to a target system. The target system can be a cluster system, etc. The cluster system can be a group of independent computers interconnected by a high-speed network, which form a group and are managed in a single system mode. When a client interacts with the cluster system, the cluster system can be regarded as an independent server. Cluster configuration can improve availability and scalability.

[0023] In an embodiment of the present specification, the target system may include a configuration file and a filter chain. The configuration file may include a correspondence between flow control indicators and counters, each counter corresponds to a filter, and the filter chain may include at least a global filter. Among them, the counter corresponding to the global filter can be used to record the concurrency of the entire target system. The counters corresponding to other filters can be used to record the concurrency of the corresponding flow control indicator scenario.

[0024] In some implementation scenarios, the flow control indicator may include at least one of the following: transaction identification; front-end system identification; institution identification; a combination of transaction identification, front-end system identification and institution identification; back-end system identification; customer identification; a combination of customer identification and transaction identification; deployment unit identification; a combination of transaction identification and preset field content.

[0025] In some implementation scenarios, the correspondence between the flow control indicator and the counter may include many-to-one or one-to-one.

[0026] In some implementation scenarios, a configuration file may be created in advance in the target system, and then the corresponding relationship between the flow control indicator and the counter may be configured through the configuration file.

[0027] Specifically, for example, in some implementation scenarios, for business transactions, you can first configure a transaction group counter through a configuration file, and set the counting threshold (also called the maximum flow control number) of the transaction group counter to 100, and then configure the transaction identifier of a certain business transaction to point to the transaction group counter, thereby establishing a correspondence between the transaction identifier and the counter. Among them, the correspondence between the transaction identifier and the transaction group counter can be n:1, n≥1, that is, multiple transactions can point to the same transaction group counter. Business can also be called business transaction, which means a program to implement a specific business. Each business transaction corresponds to a transaction identifier. The transaction identifier can also be called a transaction code, which can be composed of one or more of numbers, letters, characters, etc.

[0028] For the front-end system (or back-end system), since each front-end system (or back-end system) has a corresponding front-end system identifier (or back-end system identifier), and the number of front-end systems (or back-end systems) is usually limited, the flow control number changes in the scenario is relatively small, so the correspondence between the front-end system identifier and the counter (or the correspondence between the back-end system identifier and the counter) and the maximum flow control number of the counter can be directly configured in the configuration file. Among them, the correspondence between the front-end system identifier and the counter (or the correspondence between the back-end system identifier and the counter) can be 1:1. The front-end system can be understood as a system that needs to access the target system. The front-end system can achieve system interaction by calling the business transaction of the target system. The back-end system can be understood as a third-party system that the target system needs to access. The target system can achieve system interaction by calling the business transaction of the back-end system. Setting flow control based on the front-end system dimension can limit the flow of the front-end system accessing the target system, thereby ensuring the stability of the target system resources and normal operation. Setting flow control based on the back-end system dimension can flexibly control the flow sent to the back-end system due to the different concurrent processing capabilities of the back-end system.

[0029] For an organization, you can first configure an organization group counter through the configuration file, and set the counting threshold of the organization group counter (also called the maximum flow control number) to 100. Then you can configure the organization ID of an organization to point to the organization group counter, thereby establishing a correspondence between the organization ID and the counter. Among them, the correspondence between the organization ID and the organization group counter can be n:1, n≥1, that is, multiple organizations can point to the same organization group counter. Among them, the target system can set up different organizations according to different regions or specific businesses. Setting flow control based on the organization dimension can provide greater resource support for organizations with relatively large business transaction volumes.

[0030] For business transactions + front-end systems + institutions, you can first configure a group counter through the configuration file, and set the counting threshold of the group counter (also known as the maximum flow control number) to 100, and then configure the combination of transaction identification, front-end system identification and institution identification (such as transaction identification | front-end system identification | institution identification) to point to the group counter, thereby establishing a correspondence between the combination of transaction identification, front-end system identification and institution identification and the counter. Among them, the correspondence between the combination of transaction identification, front-end system identification and institution identification and the group counter can be n:1, n≥1, that is, multiple combinations of transaction identification, front-end system identification and institution identification can point to the same group counter. Among them, setting flow control in the dimensions of business transactions + front-end systems + institutions can focus on increasing the flow control quota for key institutions when resources are limited, and achieve the optimal solution for resource utilization.

[0031] In addition, for customers, customers + business transactions, deployment units, business transactions + preset field content, the process of establishing corresponding relationships with counters is similar to the establishment process of the above-mentioned business transactions, business transactions + front-end systems + institutions, and can be referenced to each other, so no further description is given. Among them, customers represent users who use the target system, each customer has a unique customer identifier, and each customer has two associated attributes: a front-end system identifier belonging to different front-end systems, and an institution identifier belonging to different institutions. Deployment units represent clusters that handle a certain type of business, and deployment units may include multiple machines. A deployment unit corresponds to a deployment unit identifier. The preset field content may represent a field in a transaction request message, transmitting specific business information. In some implementation scenarios, transaction requests transmit business data in the form of XML messages. The preset field content may be set according to the actual scenario, and this specification does not limit this. Setting flow control in the customer dimension can achieve the tilt of system resources for specific important customers. Setting flow control in the customer + business transaction dimension can achieve the tilt of system resources for specific important customers for some important transaction resources or transactions with fierce competition. By setting flow control based on the deployment unit dimension, you can set a lower flow control value for deployment units with fewer resources when the system resources of different business deployment units are inconsistent. By setting flow control based on the business transaction + preset field content dimension, you can flexibly implement flow control quota control.

[0032] It should be noted that in the filter chain, the filter corresponding to the counter corresponding to the combined flow control indicator can be prioritized. In some implementation scenarios, when the combined flow control indicator is identified in the business request, the filter corresponding to the counter corresponding to the combined flow control indicator can be directly used for judgment without subsequent filter judgment.

[0033] Of course, the above is only an exemplary explanation. The flow control indicators and the way of configuring the relationship between the flow control indicators and the counters are not limited to the above examples. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0034] The following is an example of a specific application scenario to illustrate the implementation plan of this specification. Specifically, Figure 1 It is a flowchart of an embodiment of a method for determining flow control data provided in this specification. Although this specification provides method operation steps or device structures as shown in the following embodiments or drawings, the method or device may include more or fewer operation steps or module units after partial combination based on routine or no creative labor.

[0035] It should be noted that the following embodiment description does not limit the technical solutions in other application scenarios that can be extended based on this specification. Figure 1 As shown, in an embodiment of a method for determining flow control data provided by this specification, the method may include the following steps.

[0036] S10: receiving a service request and determining a flow control indicator of the service request.

[0037] The business request may be a request for accessing a resource file of a target system, etc. The business request may also be referred to as a business transaction request or a transaction request.

[0038] In some embodiments, the service request may be sent by a client, a third-party organization or system, etc. that interacts with the target system.

[0039] In some embodiments, after receiving a business request, the target system can identify the flow control indicator corresponding to the business request. Specifically, for example, in some implementation scenarios, after receiving a business request, the target system can determine the flow control indicator corresponding to the business request according to the information carried in the business request. In other implementation scenarios, after receiving a business request, the target system can obtain the corresponding business information from the local storage or remote storage according to the business request, and then determine the flow control indicator corresponding to the business request according to the business information. Among them, the local storage can be the memory of the target system, etc. The remote storage can be a third-party system that communicates with the target system, etc. The business information corresponding to each business can be pre-stored locally or remotely, such as the business operation process, the information used in the business operation process, etc. Of course, the above is only an exemplary description, and the method of determining the flow control indicator corresponding to the business request is not limited to the above example. The technical personnel in the relevant field may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0040] In some implementation scenarios, the flow control indicator may include at least one of the following: transaction identification; front-end system identification; institution identification; a combination of transaction identification, front-end system identification and institution identification; back-end system identification; customer identification; a combination of customer identification and transaction identification; deployment unit identification; a combination of transaction identification and preset field content.

[0041] S12: Determine a filter chain corresponding to the service request according to the corresponding relationship between the flow control indicator and the counter.

[0042] In an embodiment of the present specification, after determining the flow control index corresponding to the business request, the filter chain corresponding to the business request can be determined according to the correspondence between the flow control index and the counter in the configuration file. Among them, the filter chain corresponding to the business request includes at least a global filter. In the configuration file, the correspondence between the flow control index and the counter can include many-to-one or one-to-one. Each filter (Filter) corresponds to a filtering rule. According to the filtering rule, it can be determined whether the business request can pass the filter. The filtering rules of each filter can be the same or different.

[0043] In some embodiments, after determining the flow control indicator corresponding to the service request, the flow control indicator corresponding to the service request can be used to match in the configuration file, thereby determining the counter corresponding to the flow control indicator. Further, since each counter corresponds to a filter, the filter included in the filter chain corresponding to the service request can be determined according to the counter corresponding to the flow control indicator.

[0044] In some implementation scenarios, when matching the flow control indicators corresponding to the business request in the configuration file, one or more flow control indicators may not have corresponding counters. In this case, you can only obtain the matched counters, and then determine the filter chain corresponding to the business request based on the filters corresponding to the matched counters.

[0045] Of course, in some implementation scenarios, the correspondence between the flow control indicators and the counters in the configuration file can also be updated. For example, the flow control indicators that do not appear in the configuration file can be added to the configuration file in real time or periodically, and the counters can be configured accordingly. For another example, the correspondence between the flow control indicators and the counters in the configuration file can be changed according to the actual scenario requirements.

[0046] S14: Determine whether to perform business processing based on the filter chain corresponding to the business request.

[0047] In the embodiment of the present specification, after determining the filter chain corresponding to the service request, it can be determined whether to perform service processing based on the filter chain. The filter chain is used to determine whether to perform service processing and then access resource files.

[0048] In some embodiments, determining whether to perform business processing based on the filter chain corresponding to the business request may include: submitting the business request to a global filter; determining whether the business request satisfies the filtering rule corresponding to the global filter; if it is determined to be satisfied, determining whether the filter chain includes a first filter; if it is determined not to include, determining to perform business processing. The first filter may be any filter except the global filter.

[0049] Since the filter chain includes at least a global filter, when determining whether to perform business processing based on the filter chain, the business request will inevitably be submitted to the global filter to determine whether the business request meets the filtering rules of the global filter.

[0050] In some implementation scenarios, determining whether the business request satisfies the filtering rules corresponding to the global filter may include: obtaining the current data recorded by the counter corresponding to the global filter; adding 1 to the current data to obtain first data; determining whether the first data is greater than a first threshold; the first threshold is the counting threshold of the counter corresponding to the global filter; when the first data is not greater than the first threshold, determining that the business request satisfies the filtering rules corresponding to the global filter.

[0051] In some implementation scenarios, when the first data is greater than the first threshold, it can be determined that the service request does not meet the filtering rule corresponding to the global filter. At this time, the first data can be reduced by 1 and the information that the flow control is exceeded can be returned. Each counter has a corresponding counting threshold, that is, the maximum flow control number, which can be set according to the actual scenario, and this specification does not limit this.

[0052] In some implementation scenarios, since the filter chain may include other filters in addition to the global filter, when it is determined that the business request satisfies the filtering rule corresponding to the global filter, it can be determined whether the filter chain includes the first filter.

[0053] In some implementation scenarios, when it is determined that the first filter is not included, it can be indicated that the business request has passed the filter chain, and business processing can be performed and resource files can be accessed.

[0054] In some implementation scenarios, when it is determined that the first filter is included, the business request can be submitted to the first filter; it is determined whether the business request satisfies the filtering rule corresponding to the first filter; when it is determined that it satisfies, it is determined whether the filter chain includes a second filter; when it is determined that it does not include, it is determined to perform business processing. The second filter can be any filter except the global filter and the first filter.

[0055] In some implementation scenarios, determining whether the business request satisfies the filtering rules corresponding to the first filter may include: obtaining the current data recorded by the counter corresponding to the first filter; adding 1 to the current data to obtain second data; determining whether the second data is greater than a second threshold; the second threshold is the counting threshold of the counter corresponding to the first filter; when the second data is not greater than the second threshold, determining that the business request satisfies the filtering rules corresponding to the first filter.

[0056] In some implementation scenarios, when the second data is greater than a second threshold, it can be determined that the business request does not satisfy the filtering rule corresponding to the first filter. At this time, the second data can be subtracted by 1 and information that exceeds flow control can be returned.

[0057] It should be noted that if there are multiple filters in the filter chain, the business request can be submitted to the next filter for filtering in sequence if it meets the filtering rules of the previous filter. When the filtering conditions of all filters are met, it can be said that the business request has passed the filter chain, and business processing can be performed and resource files can be accessed. If the filtering conditions of a certain filter are not met in the middle, the business request will be processed by the filter and cannot enter the subsequent filters, which means that the business request has not passed the filter chain and business processing cannot be performed. Among them, the arrangement order of filters in the filter chain can be pre-configured in a preset file (such as a web.xml file), and the specific arrangement order can be set according to the actual scenario, and this manual does not limit this.

[0058] S16: When it is determined to perform business processing, the target flow control data corresponding to the business request is obtained; the target flow control data includes the flow control data of each filter in the filter chain, and the flow control data includes the current data recorded by the counter corresponding to the filter.

[0059] In the embodiment of the present specification, when it is determined to perform business processing, the target flow control data corresponding to the business request can be obtained. Among them, the target flow control data includes the flow control data of each filter in the filter chain. The flow control data of each filter may include the current data recorded by the counter corresponding to the filter. The counter corresponding to the global filter can be used to record the concurrency of the entire target system. The counters corresponding to other filters can be used to record the concurrency of the corresponding flow control indicator scenario.

[0060] In some embodiments, when it is determined to perform business processing, after obtaining the target flow control data corresponding to the business request, the business program can be entered to perform business processing. When the business processing is completed, the target flow control data can be subtracted by 1.

[0061] In some embodiments, when the service processing is completed, the service processing result can also be obtained and returned to the client, where the client can be a terminal that sends a service request.

[0062] In some embodiments, the target system may also receive a flow control query request, obtain current data recorded by a counter corresponding to each filter in the target system, and then display the current data on a monitoring page.

[0063] Specifically, for example, in some implementation scenarios, the target system can receive the flow control query request sent by the monitoring system, obtain the current data recorded by each counter, and then display the obtained current data on the flow control monitoring page provided by the monitoring system, so that the staff can intuitively see the current concurrency and flow control in the system memory. Among them, the current data may include the system concurrency (also called the system flow control number) and the personalized scene concurrency (also called the personalized scene flow control number). The system concurrency is the data recorded by the counter corresponding to the global filter, and the personalized scene concurrency is the data recorded by the counter corresponding to other filters except the global filter.

[0064] In some embodiments, it may also include: determining whether the current data recorded by the counter corresponding to each filter is greater than a preset threshold; when it is determined that it is greater than the preset threshold, issuing a prompt message. The preset threshold can be set according to the actual scenario, for example, it can be 60% of the counting threshold of each counter, 80% of the counting threshold of each counter, etc. The prompt message can be issued in the form of text, audio, etc., which is not limited in this specification.

[0065] Specifically, for example, in some implementation scenarios, after obtaining the current data recorded by the counter corresponding to each filter in the target system, it can be compared with the preset threshold (e.g., 60% of the counting threshold). If it exceeds the preset threshold, an alarm tone is issued and a text message is sent to the operation and maintenance personnel to remind them whether the current concurrency is normal and whether the flow control needs to be adjusted.

[0066] The embodiments of this specification can quickly and accurately determine the flow control data of the system, thereby effectively avoiding missing the golden time for solving the problem and improving the operating efficiency of the system.

[0067] In order to further verify the practicality and feasibility of this method, this specification also provides an embodiment of applying the above solution. Figure 2 The figure is a flow chart of an embodiment of a method for determining flow control data provided in this specification.

[0068] Specifically, in this embodiment, a configuration file can be designed in the application system in advance, and a system default flow control counter default_counter is defined in the configuration file, the maximum flow control number of default_counter is set to n, and a flow control counter txn_counter_1 of a specific dimension is defined, and the maximum flow control number of txn_counter_1 is set to m.

[0069] Furthermore, you can use the Java language to design a class Class that is loaded when the application system starts. In the class, use static to declare a ConcurrentHashMap member variable as flowctlMap, read the name of the flow control counter configured in the configuration file as the Key, and store the count of the corresponding flow control counter as the Value in flowctlMap. At the same time, you can create a static variable remoteFlowMap for the current number of concurrencies used. It should be noted that Java's static member variables are static member variables, which can also be called class variables. The life cycle of a class variable is the same as that of a class and is valid throughout the execution of the application. Static variables are shared by all objects and there is only one copy in memory. For example Figure 3 As shown, it is a schematic diagram of the Java virtual machine running memory provided in this specification, wherein the Java virtual machine running memory includes multiple threads and shared memory, each thread (thread 1, thread 2, thread 3) corresponds to a PC register, a stack, and a local method stack, the shared memory includes a method area and a heap, and the method includes a runtime constant pool. Static variables are stored in the method area of ​​the shared memory during the JVM operation process, so the flowctlMap generated above always exists during the system operation process and is shared by threads.

[0070] Next, you can add multiple business transactions pointing to the counter txn_counter_1 in the configuration file, such as configuring business transaction txn1 to point to the counter txn_counter_1, and business transaction txn2 to point to the counter txn_counter_1, so that different flow controls can be implemented for specific business transaction requests. Here, business transaction txn1 can be understood as the aforementioned flow control indicator.

[0071] Finally, when a service request is received, the filter in Java can be called to implement flow control. Figure 4As shown, it is a flowchart provided by this specification for calling a filter to determine whether to perform business processing when receiving a business request. Among them, the filter chain includes at least one filter, such as Filter1, Filter2, ..., Filtern in the figure. n represents the number of filters, which can be set according to the actual scenario. The order of each filter in the filter chain is related to the order in which it is configured in web.xml, and the one configured in front is located at the front end of the filter chain. In specific implementation, the received business request can be submitted to the first filter (Filter1) in the filter chain for filtering. If the filtering rule of Filter1 is met, it is released and submitted to the next filter (Filter2) in the filter chain for filtering. Further, Filter2 can determine whether the business request meets the filtering rule of Filter2. If it is met, it is released and submitted to the next filter in the filter chain for filtering, and so on, until the filtering rule of each filter in the filter chain is met, it is determined to perform business processing. Among them, when the business request meets the filtering rules of all filters in the filter chain, the business request can access the resource file. If the business request does not meet the filtering rule of a certain filter, it cannot pass the filter, so that the business processing cannot be performed. It should be noted that if a service request cannot pass a filter, the service request will be processed in the filter. After the service request is processed by the filter, the filter chain can feedback to the client that sent the service request that the filtering rules are not met.

[0072] like Figure 5 As shown, it is a flowchart of the business request provided by this specification submitted to the filter for processing. Among them, in the configuration file, flowctlMap is used to store the maximum flow control number n of the system default flow control counter default_counter and the maximum flow control number m of the flow control counter txn_counter_1 in the business transaction dimension, and remoteFlowMap is used to store the current used concurrency number of default_counter and the current used concurrency number of txn_counter_1. Specifically including the following steps: the transaction identifier points to the counter txn_counter_1.

[0073] Specifically, after the business request enters the Filter processing, the flow control indicator corresponding to the business request can be determined as the transaction identifier based on the information carried in the business request. Then, the target system can obtain the count value corresponding to the default_counter in the remoteFlowMap from the memory, and perform an addition operation, and compare the result after the addition operation with the maximum flow control number n of the default_counter in the flowctlMap.

[0074] If it exceeds n, the result after the addition operation can be subtracted by 1, and the excess flow control information is returned. If it does not exceed, check whether the counter corresponding to the transaction identifier is configured in the configuration file according to the flow control indicator corresponding to the business request (the counter corresponding to the flow control indicator can also be called a personalized flow control counter). In this embodiment, the configuration file is configured with a counter txn_counter_1 corresponding to the transaction identifier, then the count value corresponding to txn_counter_1 in remoteFlowMap can be obtained from the memory, and an addition operation can be performed to compare the result after the addition operation with the maximum flow control number m of txn_counter_1 in flowctlMap. Among them, if the configuration file is not configured with a counter corresponding to the transaction identifier, the business processing can be entered.

[0075] Furthermore, if it exceeds m, the result after the addition operation can be subtracted by 1, and the excess flow control information is returned. Since the flow control indicator corresponding to the business request determined according to the information carried in the business request only includes the transaction identifier, if it does not exceed m, the business process can be entered. Among them, when it is determined to enter the business process, the current count values ​​of txn_counter_1 and default_counter can be obtained as the target flow control data corresponding to the business request.

[0076] Finally, after the service processing is completed, the service processing result can be returned to the client that sent the service request. Furthermore, the current count values ​​of txn_counter_1 and default_counter can be reduced by 1 to release the flow control data so that other service requests can enter.
