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 a method and an apparatus for controlling interface current limiting, and an electronic device.

Background

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

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

When the access amount or the request amount of a system is large, a current limiting manner may be needed to limit the service traffic of the system. Current limiting protects the system by rate limiting concurrent access/requests or by rate limiting requests within a time window, and can deny service once the limiting rate is reached. For an application system, there must be a limit number of concurrency/requests, that is, there is always one TPS/QPS threshold, and if the threshold is exceeded, the system may not respond to the user request or respond relatively slowly, so the application system can perform overload protection to prevent a large number of requests from flooding the system. Similarly, the interface may have burst access, and if the access amount is too large, the system traffic may be seriously affected by the crash. Therefore, it is necessary to limit the total concurrent/requested total number of interfaces, and a corresponding threshold value can be set for each interface.

The interface current limiting, the granularity is thinner, when the flow transships and leads to the system to break down, can exchange resources such as system CPU with minimum cost through the current limiting work of isolated, cancel the current limiting again until the fault recovery, make the system be unlikely to thoroughly collapse, guarantee holistic stability.

However, the inventor researches and discovers that the existing interface current limiting has some defects:

interface current limiting is different from overall current limiting of a system, reasonable threshold values are required to be set for different interfaces according to actual flow of the interfaces and load bearing capacity of the system, generally, the number of the interfaces of the system is relatively large, a large number of current limiting configurations and strategies need to be manually maintained, great maintenance cost is caused, and omission easily occurs;

when the current limiting interface reaches a certain magnitude, the maintenance and management are difficult to carry out;

the situation that the current limit is forgotten to be accessed may occur in a core interface newly added to the system;

the non-primary interfaces of part of the core modules have large flow, potential stability hidden danger exists, but the potential stability hidden danger is not combed;

the interface current limiting threshold is in a hard coding form, and the time consumption of operation is long when the system has an emergency and needs to adjust the current limiting threshold in an emergency;

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

the current limiting is lossy, and the system may be affected much by limiting the current of the core interface.

Based on the description of the above problems, the present application provides an interface current limiting control method, an interface current limiting control apparatus, and an electronic device, which can effectively solve the above technical problems.

To facilitate understanding of the present embodiment, a detailed description is first given of an operating environment for executing the interface current limiting control method disclosed in the embodiments of the present application.

Example two

To facilitate understanding of the present embodiment, a detailed description is first provided for an interface current limiting control method disclosed in the embodiments of the present application.

Referring to fig. 3, fig. 3 is a flowchart illustrating an interface current limiting control method according to an embodiment of the present disclosure. The method in this embodiment may be applied to an application system management device, and is used to control and manage the traffic of each interface in the application system. Specifically, the method in the embodiment of the present application may include the following steps.

Step S301, interface data of a server in the system to be managed is acquired.

The interface current-limiting control method in this embodiment is used to manage the flow of an application system, and before setting the interface threshold, the interface usage data in the server in the application system may be obtained first. That is, the system to be managed may be an application system.

The interface data may include access records received by the server, types of accesses received, processing amounts for various time periods, transaction processing speeds, transaction processing capabilities, 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 a log in the server, so that 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 parameters of the server itself.

After the interface data is acquired, the data may be pre-processed. Because different domain names actually correspond to the same interface at the back end, the related data of the same interface at the back end corresponding to the different domain names needs to be merged. The merged content may include the access amount corresponding to each domain name.

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

Step S302 may be used to perform initial current limiting threshold setting on the application system, or perform current limiting threshold updating on the interface having the current limiting threshold already set.

Step S302 may include: calculating to obtain an interface index of each interface according to the interface data; and configuring a current limiting threshold value for the interface of the 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 can be set; if the value of the interface index is small, a relatively small current limit threshold may be set.

Calculating interface indexes of each interface according to the interface data, wherein the step 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 time period may be a time period of one day, one week, one month, or the like. Of course, the set time period may also refer to a time period from the application system starting to be applied to the current time, or other time periods that can better represent the operating state of the interface.

Further, the index of each interface can be calculated. The index may include data that can indicate the Transaction capability of the interface, such as the number of times Per Second requests have been processed (QPS), the number of transactions processed Per Second (TPS), and the like. QPS is a measure of how much traffic a particular query server processes within a specified time, and the performance of a machine as a domain name system server can be measured in terms of query rate per second.

The calculation of the number of requests per second for a server is described below by way of an example.

For example, 70% of the day's visits are concentrated in 20% of the time, which 20% of the time is called the peak time. Peak time per second request (QPS) — (total PV > 70%)/(seconds per day > 20%); the required machine is the peak time per second QPS/QPS of a single machine. Wherein, PV number represents (page view, Chinese called: page view amount). In one example, if 300w PV is on a single machine per day, the QPS required for that machine is calculated as: (3000000 × 0.7)/(86400 × 0.2) ═ 139 (QPS). If the QPS of 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 may be acquired and used when each index needs to be used.

The current limiting threshold is correspondingly set according to the index of the interface, so that the application system can be prevented from being crashed, the processing function of the interface can be better utilized, and the interface resource can be used to the maximum extent.

Considering that the amount of requests received by the server may be different in different time periods, only the processing situation of the server at one time can be reflected in different time periods. Therefore, with the wide use of the application system, the current limiting threshold may not be well adapted to the current requirement, and the current limiting threshold may be adaptively adjusted.

In view of the above, as shown in fig. 4, step S302 may also include the following steps.

Step S3021, obtaining a flow rate of an interface 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, such as the last day, last three days, last week, last month, etc. The flow condition of the application system can be shown through a recent period of time, so that whether the current flow limiting threshold value meets the requirement or not can be reflected. For example, if the current threshold is lower than the average access amount of the set time period, or lower than a certain proportion of the average access amount of the set time period, for example, the certain proportion may be 70%, 80%, etc., it indicates that the current threshold may be too low to be set reasonably.

And step S3022, calculating the flow representation value of each interface in the set time period according to the flow of the set time period.

Wherein the flow rate performance value represents a flow rate trend of the set time period. The flow rate representative value may be an average value of the flow rate for a set period of time; or the average flow of the peak time period in the set time period; it may also be a maximum flow for a set period of time.

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

Specifically, that is, step S3023 may include determining whether the flow rate representative value is within a set proportion smaller than the current flow limiting threshold.

If the flow representation value is not within the limited range corresponding to the current flow limiting threshold value, executing step S3024; if the flow representation value is judged to be in the limited range corresponding to the current flow limiting threshold value, the current flow limiting threshold value can also meet the requirements in an application system, and the flow limiting threshold value does not need to be adjusted.

The limited 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, if the flow rate performance value is an average value of the flow rate in the set time period, 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 the like.

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

In another embodiment, if the flow rate performance value is the maximum flow rate value of the set time period, the limited 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, and the like.

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

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

In one embodiment, the new flow restriction threshold may be configured to be twice, three times, four times, etc. the flow representation value if an average of the flow for a set period of time.

In another embodiment, the new flow limiting threshold may be configured to be 1.5-2 times the flow representation value, etc., if the flow representation value is the average flow of the peak time period in the set time period.

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

Of course, the specific current limiting threshold value can be adjusted according to the actual use trend of the application system. For example, the user growth rate of the application system is relatively fast, and the current limiting threshold can be adjusted to be large.

The maximum flow values of the interfaces in the last day and week are screened out by inquiring the domain names, urls, threshold values, the access layers and 911 configurations of all the 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 flow values, so that problems can be found and positioned in time. Such as finding the QPS of the interface rises, exceeding or approaching the set threshold, and the source of the traffic growth is not abnormal, the threshold configuration of the interface can be adjusted appropriately. Therefore, the system can operate quickly when the current limiting threshold value needs to be adjusted urgently in case of emergency, some emergency conditions of the application system can be adapted, and the adaptability of the application system is improved.

Step S303, the current limiting threshold is pushed to a corresponding server, so that the server reads the current limiting threshold, and the interface flow is controlled according to the current limiting threshold.

As users of the application system increase, some original data interfaces may not be able to meet the requirements of the users for accessing the application system, and therefore some new interfaces may be accessed, and the new interfaces may not be allocated with the current limiting threshold, which may cause the traffic of the new interfaces to be relatively large. 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 may be weekly, daily, every ten days, etc. The user growth condition can be specifically determined according to the update condition of the application system.

Specifically, the set time law may be a user-defined time law, 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 obtained, the method further includes: 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; and if not, configuring a current limiting threshold value for the target interface.

In an embodiment, the step of selecting a target interface satisfying a set 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 a target interface satisfying a set rule according to the interface data includes: and selecting a target interface corresponding to the designated identifier according to the interface data.

The specified identifier may be an identifier that identifies an interface, such as a specified machine code, a target interface for the specified identifier, or the like.

In another embodiment, the step of selecting a target interface satisfying a set 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 interface discovery, and a new core interface which is not accessed with the current limiting function or an interface with higher flow rate is discovered through self-defining an interface discovery rule so as to ensure the continuous effectiveness of the current limiting function and prevent the sudden flow rate of the interface from threatening the service stability.

In order to facilitate operation of some users, an operation interface can be provided, so that the users can adjust the current limiting threshold value according to the requirements of the users.

The interface current limiting control method of the embodiment further includes: receiving a current limiting threshold configured for a designated interface; and pushing the current limiting threshold value to a corresponding server so that the server reads the current limiting threshold value and controls the interface flow according to the current limiting threshold value.

The staged current limiting is substantially lossy as long as the current limiting operation occurs. Therefore, to reduce the loss, the priority can be set for each interface in the application system, for example, the interfaces can be classified according to the importance degree of the interfaces, and divided into two or three stages, and when a specific fault occurs, the current limit switch will be according to: the three-level interface- > the two-level interface- > part of the one-level interface are sequentially opened, so that the influence on the main process is reduced as much as possible, and the integral stability of the system is kept. Wherein, the first level interface is more important than the second level interface, and the second level interface is more important than the third level interface.

Specifically, the interface current limiting control method in this embodiment further includes: and if the plurality of interfaces reach the current limiting threshold value, gradually starting the current limiting switch according to the priority of each interface in the plurality of interfaces, wherein the interface with the lower priority starts the current limiting switch before the interface with the higher priority.

In this embodiment, the current limiting of each interface may be implemented by starting an interface current limiting algorithm.

Specifically, the current limiting algorithm in the present embodiment may include a token bucket algorithm, a leaky bucket algorithm, a calculator, and the like. One skilled in the art can select any one of the above current limiting algorithms to perform current limiting operations on the interface in light of the present disclosure. The current limiting algorithm used is not limited in this embodiment.

The principle of token bucket algorithm is that the system will put tokens into the bucket at a constant rate, and if the request needs to be processed, it will need to first get a token from the bucket, and if no token is available in the bucket, it will refuse service. In the interface current limiting method applied to the application, when a token in a token bucket algorithm of an interface in an application system is used up, the interface cannot be accessed any more.

The method in the embodiment can uniformly manage interface current limiting configuration by establishing a current limiting platform; the new interface is automatically found, and a large-flow interface is found according to the monitoring data; the rationality of the current limiting threshold is self-discovered, and an interface with unreasonable threshold is screened out through a system general strategy or a user-defined strategy and is adjusted in time; accessing a third-party platform, flexibly managing the current-limiting configuration, namely using the current-limiting configuration after changing, and taking effect in real time; grading interfaces and sequentially limiting current according to importance degree;

the current limiting rule in the control current limiting configuration in this embodiment is not directly configured on an http server (such as nginx), but is controlled by a management platform provided in this embodiment. When the interface current limiting needs to be modified in an emergency, the interface current limiting can be directly operated and issued on the management platform in the embodiment, the interface current limiting takes effect in real time, and the method is quicker and more convenient than the method of directly modifying the current limiting configuration on a machine.
