Description

Interface current limiting control method and device and electronic equipment

Technical Field

The present application relates to the field of network technologies, and in particular, to an interface current limiting control method and device, and an electronic device.

Background

Currently, there are three ways in which a high concurrency system can be used to protect the system: caching, demoting, and throttling. The purpose of the cache is to improve the system access speed and increase the capacity which can be processed by the system; degradation is when a problem is serviced or the performance of the core flow is affected, then the problem needs to be temporarily shielded, and the problem is opened after the peak or problem is solved. Some scenarios cannot be solved by caching and degradation, such as scarce resources (second kill, robbery), write services (comments, orders), frequent complex queries (last few pages of comments), and therefore a means is needed to limit the concurrency/request amount of these scenarios, i.e. current limit. However, since there are many interfaces in one system, the current limiting configuration for each interface is relatively complex, resulting in troublesome current limiting operation.

Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.

When the access or request amount of a system is large, a current limiting manner may be required to limit the service traffic of the system. The throttling protects the system by throttling concurrent accesses/requests or requests within a time window, and once a limiting rate is reached, service may be denied. There must be a limited number of concurrency/request for an application system, i.e. there is always a TPS/QPS threshold, and if the threshold is exceeded, the system may not respond to user requests or respond relatively slowly, so the application system may be overload protected from large numbers of requests flooding the system. Also, the interface may have burst access, and if the access amount is too large, the crash may have serious impact on the system service. Thus, there is a need to limit the total number of concurrent/requested interfaces, and a corresponding threshold may be set for each interface.

Interface current limiting, granularity is finer, and when the flow overload leads to the system to break down, resources such as system CPU can be replaced with minimum cost through isolated current limiting work, and current limiting is cancelled again until the fault is recovered, so that the system is not thoroughly broken down, and overall stability is ensured.

However, the inventor researches find that the current interface current limiting has some defects:

interface current limiting is different from the whole current limiting of a system, reasonable thresholds are required to be set for different interfaces according to the actual flow and the system load bearing capacity of the interfaces, and in general, the number of the interfaces of the system is relatively large, so that a large number of current limiting configurations and strategies are required to be manually maintained, great maintenance cost is caused, and omission is easy to occur;

when the current limiting interface reaches a certain level, the maintenance and the management are difficult;

the newly added core interface of the system can be forgotten to be accessed for current limiting;

the flow of the non-primary interface of part of the core modules is large, potential stability hidden danger exists, but the non-primary interface of part of the core modules may not be carded;

the interface current limiting threshold is in a hard coding form, the emergency situation occurs in the system, and the operation time is long when the current limiting threshold needs to be adjusted urgently;

the current limiting threshold cannot be dynamically adjusted, and as the flow of the system increases, the previously set threshold may be unreasonable, so that the system has high risk;

The current limiting is lossy, and the core interface may be greatly affected by the current limiting.

Based on the description of the problems, the interface current limiting control method, the device and the electronic equipment can effectively solve the technical problems.

For the sake of understanding the present embodiment, first, an operation environment for executing an interface current limiting control method disclosed in the embodiments of the present application will be described in detail.

Example two

For the sake of understanding the present embodiment, first, a detailed description is given of an interface current limiting control method disclosed in the embodiments of the present application.

Referring to fig. 3, fig. 3 shows a flowchart of an interface current limiting control method according to an embodiment of the present application. The method in the embodiment can be applied to an application system management device for controlling and managing the flow of each interface in an application system. Specifically, the method in the embodiment of the application may include the following steps.

Step S301, obtaining interface data of a server in a system to be managed.

The interface current limiting control method in this embodiment is used for managing the traffic of an application system, and the interface usage data in the server in the application system can be acquired before the interface threshold is set. That is, the system to be managed may be an application system.

The interface data may include an access record received by the server, a type of access received, a throughput for each time period, a transaction speed, a capability to process a transaction, and the like.

Specifically, the access record, the received access type and the processing amount of each time period in the interface data may be stored in the log in the server, and then part of the interface data may be obtained by obtaining the log of each server. In addition, other contents in the interface data can also be obtained by obtaining the parameters of the server itself.

After the interface data is acquired, the data may be preprocessed. Because there are cases where different domain names actually correspond to the same interface at the back end, it is necessary to combine the related data of the same interface at the back end corresponding to different domain names. The consolidated content may include access amounts corresponding to the respective domain names.

Step S302, a current limiting threshold is configured for the interface of the server in the system to be managed according to the interface data.

Step S302 may be used to perform initial current limit threshold setting on the application system, or perform current limit threshold updating on the interface to which the current limit threshold has been set.

Step S302 may include: calculating according to the interface data to obtain interface indexes of each interface; and configuring a current limiting threshold for an interface of a server in the system to be managed according to the interface index.

In this embodiment, the value of the interface index is relatively large, and a relatively large current limiting threshold value may be set; if the value of the interface indicator is relatively small, a relatively smaller current limit threshold may be set.

The step of calculating the interface index of each interface according to the interface data comprises the following steps: and calculating the query rate per second of each interface in a set time period according to the interface data, and taking the query rate per second as an interface index.

The set period may be a period of one day, one week, one month, or the like. Of course, the set period of time may also refer to a period of time when the application system begins to apply to the current time, or other period of time, that is better able to represent the operational state of the interface.

Further, the index of each interface can be calculated. The metrics may include data that can represent the transaction capabilities of the interface, such as the number of requests processed Per Second (QPS) Per Second, the number of transactions processed Per Second (Transaction Per Second, TPS), etc. QPS is a measure of how much traffic a particular query server handles in a given time, and the performance of a machine as a domain name system server can be measured in terms of query rate per second.

The method of calculating the number of requests per second for a server is described below by way of one example.

For example, 70% of the day's visits are focused on 20% of the time, which 20% of the time is called the peak time. Peak time per second request (QPS) = (total PV number 70%)/(number of seconds per day 20%); required machine = peak time QPS per second/QPS of single machine. Wherein, PV number represents (page view, chinese name: page view amount). In one example, if 300w PV per day is on a single machine, the QPS required by this machine is calculated as: (3000000 x 0.7)/(86400 x 0.2) =139 (QPS). If the QPS for a machine is 58, the number of machines needed is calculated as: 139/58=3.

In this embodiment, the calculated indexes may be stored, and the indexes may be acquired for use when each index is needed.

By setting the current limiting threshold according to the index of the interface, the application system can be prevented from crashing, the processing function of the interface can be better utilized, and the interface resource can be used maximally.

Considering that the amount of requests received by the server may be different in different time periods, only the processing situation of the server can be represented in different time periods. Therefore, with the wide use of application systems, the current limiting threshold value which may be set before cannot be well adapted to the current requirement, and then the current limiting threshold value can be adaptively adjusted.

Based on the above considerations, as shown in fig. 4, step S302 may also include the following steps.

And step S3021, obtaining the flow of the interfaces of the server in the system to be managed in a set time period according to the interface data.

The set period of time may be a recent period of time, for example, a period of time of the last day, the last three days, the last week, the last month, etc. The flow condition of the application system can be represented through a short period of time, so that whether the current flow limiting threshold meets the requirement can be represented. For example, the current limit threshold may be lower than the average access amount for the set period of time or lower than a certain proportion of the average access amount for the set period of time, for example, the certain proportion may be 70%, 80% equivalent, indicating that the current limit threshold may be lower and unreasonable to set.

Step S3022, calculating a flow expression value in the set time period of each interface according to the flow of the set time period.

Wherein the flow amount representation value represents a flow amount trend of the set time period. The flow rate expression value may be an average value of the flow rates for the set period of time; the average flow rate of the peak time period in the set time period can also be; it may also be the maximum flow value for a set period of time.

Step S3023, comparing the flow expression value of any interface with the current limit threshold of each interface of the server in the system to be managed, and determining whether the flow expression value is within the limited range corresponding to the current limit threshold.

Specifically, step S3023 may include determining whether the flow amount representation value is within a proportion less than the current flow limit threshold setting proportion.

If it is determined that the flow expression value is not within the limited range corresponding to the current limit threshold, step S3024 is executed; if the flow expression value is judged to be in the limit range corresponding to the current limiting threshold value, the current limiting threshold value can also meet the requirements in the application system, and the current limiting threshold value can be not adjusted.

The defined range corresponding to the current limit threshold may be a set proportion of the current limit threshold, for example, 90%, 80% of the current limit threshold.

In one embodiment, the flow expression value is an average value of the flow rate of the set period, and the limited range corresponding to the current flow limit threshold may be relatively small, for example, 30% of the current flow limit threshold, 40% of the current flow limit threshold, and so on.

In another embodiment, the flow expression value is the average flow in the peak time period in the set time period, and the limited range corresponding to the current flow limit threshold may be relatively large, for example, 75% of the current flow limit threshold, 85% of the current flow limit threshold, and so on.

In another embodiment, if the flow expression value is the maximum flow value of the set period, the limit range corresponding to the current flow limit threshold may be relatively large, for example, 85% of the current flow limit threshold, 90% of the current flow limit threshold, etc.

Step S3024, configuring a new current limit threshold for the corresponding interface.

The configured new current limit threshold may be a current limit threshold for which the flow amount value may match. Specifically, if the current limit threshold is smaller, step S3024 may include configuring a new current limit threshold for the corresponding interface that is greater than the current limit threshold.

In one embodiment, the flow rate representation value is an average of the flow rate for the set period of time, and the new flow limit threshold may be configured to be twice, three times, four times, etc. the flow rate representation value.

In another embodiment, the flow rate representation value is the average flow rate during the peak time period in the set time period, and the new flow limit threshold may be configured to be 1.5-2 times the flow rate representation value, etc.

In another embodiment, the new flow limit threshold may be configured to be 1.2-1.4 times the flow expression value, etc., if the flow expression value is the flow maximum for the set period of time.

Of course, the specific current limit threshold may be adjusted according to the actual usage trend of the application system. For example, the user growth rate of the application system is relatively fast, and the current limit threshold can be adapted to be increased.

The maximum flow value of the interface in the last day and week is screened out by inquiring the domain names, url, threshold values and access layer and 911 configuration of all interfaces of the system, and whether the current limiting threshold value of the previous interface is reasonable or whether the interface flow is abnormal or not is judged by analyzing the maximum flow value, so that the method can help to find and locate problems in time. For example, if the interface QPS is found to be rising, exceeding or approaching a set threshold, and the source of traffic growth is not abnormal, the threshold configuration of the interface can be appropriately enlarged. Therefore, the emergency situation of the system is realized, the operation is faster when the current limiting threshold needs to be urgently adjusted, the emergency situation of the application system can be adapted, and the adaptability of the application system is improved.

Step S303, pushing the current limiting threshold to a corresponding server so that the server reads the current limiting threshold and controls the interface flow according to the current limiting threshold.

As users of application systems increase, some original data interfaces may not be able to meet the requirements of users for accessing the application systems, and thus may access some new interfaces, which may not be assigned a current limit threshold, and may result in relatively large traffic for the new interfaces. Based on the above description, the interface data in the application system can be monitored and acquired according to a set rule.

Based on the above considerations, step S301 may be implemented as: and acquiring interface data of the server in the system to be managed according to a set time rule.

The set time law acquisition can be acquired once a week, acquired once a day, acquired once every ten days, and the like. The user growth condition can be specifically based on the update condition of the application system.

Specifically, the set time rule may be a user-defined time rule, for example, a user operation interface may be provided on the management device, and an input box for receiving data may be provided in the operation interface.

Of course, the set time law may be a default time law.

The flow state of each interface of each server in the application system can be monitored by acquiring the interface data of the server in the application system according to the set time rule.

After the interface data of the server in the system to be managed is acquired, the method further comprises: selecting a target interface meeting a set rule according to the interface data; judging whether the target interface is configured with a current limiting threshold value or not; if not, configuring a current limiting threshold for the target interface.

In one embodiment, the step of selecting the target interface that meets the setting rule according to the interface data includes: and selecting a target interface with the query rate per second larger than a set value according to the interface data.

In another embodiment, the step of selecting the target interface that meets the setting rule according to the interface data includes: and selecting a target interface corresponding to the specified identifier according to the interface data.

The specified identifier may be an identifier capable of identifying an interface, such as a specified machine code, a target interface of the specified identifier, or the like.

In still another embodiment, the step of selecting the target interface that satisfies the setting rule according to the interface data includes: and selecting a target interface corresponding to the appointed access layer according to the interface data.

The steps are used for discovering the interface, and discovering a new core interface which is not accessed to the current limitation or an interface with higher flow rate through the self-defined interface discovery rule so as to ensure the continuous effectiveness of the current limitation function and prevent the sudden flow rate of the interface from threatening the service stability.

In order to facilitate some user operations, an operation interface can be provided, so that the user can conveniently adjust the current limiting threshold according to the needs of the user.

The interface current limiting control method of the embodiment further comprises the following steps: receiving a current limit threshold configured for a specified interface; pushing the current limiting threshold to a corresponding server so that the server can read the current limiting threshold and control the interface flow according to the current limiting threshold.

The staged flow restriction is essentially lossy as long as the flow restriction operation occurs. Therefore, in order to reduce the loss, priorities may be set for the interfaces in the application system, for example, the interfaces may be classified according to the importance degree of the interfaces, and the interfaces are divided into two-level and two-level, and when a specific fault occurs, the current limiting switch will be as follows: the sequence of the three-level interface- > the second-level interface- > part of the first-level interfaces is sequentially opened, so that the influence on the main flow is reduced as much as possible, and the overall stability of the system is maintained. The primary interface is an interface which is more important than the secondary interface, and the secondary interface is an interface which is more important than the tertiary interface.

Specifically, the interface current limiting control method in this embodiment further includes: and if the interfaces reach the current limiting threshold, starting the current limiting switch step by step according to the priority of each interface in the interfaces, wherein the interface with low priority starts the current limiting switch earlier than the interface with high priority.

In this embodiment, the current limiting algorithm of the interfaces may be started to implement current limiting of the interfaces.

Specifically, the current limiting algorithm in the present embodiment may include a token bucket algorithm, a leaky bucket algorithm, a calculator, and the like. Any of the above-described current limiting algorithms may be selected by those skilled in the art to perform current limiting operations on the interface in light of the present disclosure. The present embodiment is not limited to the current limiting algorithm used.

The principle of the token bucket algorithm is that the system will put tokens into the bucket at a constant speed, and if the request needs to be processed, it needs to first acquire a token from the bucket, and when no token is desirable in the bucket, it refuses service. In the interface flow limiting method applied to the application, when tokens in a token bucket algorithm of an interface in an application system are taken out, the interface can not be accessed again.

The method in the embodiment can uniformly manage interface current limiting configuration by establishing a current limiting platform; the new interface discovers itself, and discovers the high-flow interface according to the monitoring data; the rationality self-discovery of the current limiting threshold value, screening out an interface with unreasonable threshold value through a system general strategy or a custom strategy, and timely adjusting; accessing a third party platform, flexibly managing the current limiting configuration, and enabling the current limiting configuration to be changed, used and effective in real time; interface grading, and sequentially limiting current according to the importance degree;

In the current limiting configuration control in this embodiment, the current limiting rule is not configured directly on the http server (such as nginx), but is controlled by a management platform provided in this embodiment, where the management platform in this embodiment can support a more flexible configuration rule, and can push the configuration to a corresponding machine, and then the http server on the machine reads the current limiting rule. When an emergency needs to modify the interface current limit, the interface current limit is directly operated and issued on the management platform in the embodiment, and the interface current limit takes effect in real time, so that the method is more rapid and convenient than the method of directly modifying the current limit configuration on a machine.
