[0046] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0048] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0049] like Figure 1 , 6 As shown, the automated view library service assurance system in this embodiment includes:

[0050] The collection module is used to collect resource information and cascade information of the view library service;

[0051] A fuse rule module, used to set a plurality of fuse rules having a mapping relationship with the resources and cascade configurations of the view library service; and to match the collected resource information and cascade information with the fuse rules to obtain a fuse rule to be executed;

[0052] A synchronization module, used to synchronize the to-be-executed fuse rules to the service replica;

[0053] The execution module is used to perform interface fusing on the view library service at this level according to the to-be-executed fusing rule.

[0054] In this embodiment, the acquisition module is mainly used to collect resource information and cascade information of the view library service. The resource information in this embodiment includes processor load information and network load information, such as CPU (central processing unit, referred to as CPU) usage, memory usage, and network status; cascade information includes cascade relationship, upper and lower cascade status, and cascade interface success rate. The fuse rule module is mainly used to set a variety of fuse rules that have a mapping relationship with the resources and cascade configuration of the view library service; and according to the collected resource information and cascade information, match with the fuse rule to obtain a fuse rule to be executed. The fuse rule module can provide users with the ability to modify or delete the default fuse rule and persist the fuse rule to the data persistence device. The synchronization module is used to synchronize the fuse rule to be executed to the service copy. The synchronization method can use message queues, Redis, configuration centers, etc. to achieve the synchronization function. Since for a service, it may be necessary to start multiple different applications, but service copies with the same service content, this method can improve the disaster tolerance of the service, but for running multiple services at the same time, it will involve some problems. The fuse rules to be executed can be synchronized through the synchronization module. The execution module is mainly used to perform interface fuse for the view library service at this level according to the fuse rules to be executed. For example, you can use the token bucket algorithm, leaky bucket algorithm, sliding window algorithm to implement it yourself, or use the fuse capabilities provided by the existing Guava or Sentinel.

[0055] In this embodiment, it also includes: an early warning module, which is used to compare the collected resource information with the preset alarm threshold, and issue an alarm message according to the comparison result. The early warning module can issue an alarm for the system key indicator warning to remind the user that the system status is abnormal. A recording module is used to record the execution interface fuse information. When the execution of the fuse rule causes cascade data loss, the upper and lower data are reconciled. The recording module can record the fuse time, reason and duration and the cascade data loss during the current fuse time when sending the fuse, which is used for the upper and lower data reconciliation function.

[0056] In this embodiment, the fuse rule module includes: a data persistence unit, which is used to convert between data models and storage models. The data persistence unit can provide a fuse rule storage function, and various types of databases, files, configuration centers, etc. can be used to implement this function; a visualization unit, which is used to visualize the resource information, cascade information, fuse rules, alarm information and interface fuse information; a rule modification unit, which is used to modify the fuse rules; a rule matching unit, which is used to match the collected resource information and cascade information with the fuse rules to obtain the fuse rules to be executed.

[0057] In this embodiment, the fuse rule module can generate multiple fuse rules according to system specifications and system cascade relationships. The mapping relationship in this embodiment includes the relationship between traffic and abnormality ratio, the access data interface restriction relationship, the subscription push interface restriction relationship, the control alarm push interface restriction relationship, and the cascade query interface restriction relationship; the fuse rules include the overall inlet traffic query and abnormality ratio fuse rules, the access data interface query restriction rules, the subscription push interface query restriction rules, the control alarm push interface query restriction rules, and the cascade query interface query restriction rules.

[0058] In this embodiment, a decision module is also included, which is used to select different fusing methods according to the collected resource information and cascade information and the to-be-executed fusing rules. The fusing methods in this embodiment include: by limiting the average transmission rate of the data served by the view library at this level, the interface is fused, and / or, periodically issuing tokens, if a request needs to be processed, a token is obtained, and when no token is available, the service is rejected. A flow module is used to determine the current request flow according to the flow limiting parameters in the fusing method; a time module is used to obtain the interface fusing duration when the current request flow is greater than the preset receiving flow; a recovery module is used to control the re-sending of the access request according to the interface fusing duration. In this embodiment, the processing speed of the submitted access application can be estimated according to the preset receiving flow and the number of current request flows, and then the current processing time can be obtained, and then the to-be-processed access applications can be sorted and allocated according to the priority of the corresponding requester. For example, the current required processing time can be 100ms, and the access applications of requests A, B, and C are sorted. For example, request C has the highest priority and request A has the lowest priority, so the sorting is C, B, A. It is estimated that the processing time of each access request is 10ms, so the fuse duration is 100ms for request C, 110ms for request B, and 120ms for request A. The fuse duration is sent to the corresponding requester so that the requester resends the access request based on the fuse duration. After the fuse duration is reached, the requester resends the access request.

[0059] Accordingly, this embodiment also provides an automated view library service assurance method, including:

[0060] S1. Collect resource information and cascade information of view library service;

[0061] S2. Setting a plurality of fuse rules having a mapping relationship with the resources and cascade configurations of the view library service, and matching the collected resource information and cascade information with the fuse rules to obtain a fuse rule to be executed;

[0062] S3. Synchronize the to-be-executed fuse rules to the service copy;

[0063] S4. According to the to-be-executed fuse rule, interface fuse is performed on the view library service at this level.

[0064] In this embodiment, the collected resource information includes processor load information and network load information, such as CPU (central processing unit, CPU for short) usage, memory usage, and network status; cascade information includes cascade relationship, upper and lower cascade status, and cascade interface success rate.

[0065] In this embodiment, a variety of fuse rules are set up that have a mapping relationship with the resources and cascade configuration of the view library service; and according to the collected resource information and cascade information, the fuse rules are matched to obtain a fuse rule to be executed. The fuse rule module can provide users with the ability to modify or delete the default fuse rules and persist the fuse rules to the data persistence device. The fuse rules to be executed are synchronized to the service replica. The synchronization method can use message queues, Redis, configuration centers, etc. to achieve the synchronization function. According to the fuse rules to be executed, the interface fuse is executed for the view library service at this level. For example, the token bucket algorithm, leaky bucket algorithm, sliding window algorithm can be used to implement it yourself, or the fuse capabilities provided by the existing Guava or Sentinel can be used.

[0066] In this embodiment, the resource information collected is compared with the preset alarm threshold, and an alarm message is issued according to the comparison result. The early warning module can issue an alarm for the system key indicator warning to remind the user that the system status is abnormal. When the cascade data is lost after the execution of the fuse rule, the upper and lower data are reconciled. The recording module can record the fuse time, reason and duration and the cascade data loss during the current fuse time when sending the fuse, which is used for the upper and lower data reconciliation function.

[0067] In this embodiment, a variety of fuse rules can be generated according to system specifications and system cascade relationships. The mapping relationship in this embodiment includes the relationship between traffic and abnormality ratio, the access data interface restriction relationship, the subscription push interface restriction relationship, the control alarm push interface restriction relationship, and the cascade query interface restriction relationship; the fuse rules include the overall inlet traffic query and abnormality ratio fuse rules, the access data interface query restriction rules, the subscription push interface query restriction rules, the control alarm push interface query restriction rules, and the cascade query interface query restriction rules.

[0068] The following is a specific example for explanation:

[0069] Taking the example of data that needs to flow between north-south systems and converge to the upper system, in the system, data usually needs to converge from the lower level to the upper level to the central node of the data middle platform, and the system architecture adopts a tree structure. Since the status of the upper-level system will affect the data push of the lower-level system, which in turn affects the normal business capabilities of the lower-level system. In order to avoid affecting the business of the lower-level system itself, this embodiment adds registration and keep-alive capabilities and system key indicator collection capabilities to the upper and lower levels, and then forms fuse rules for the various collected indicators. When an abnormality occurs in the upper-level system, the business ability to push data to the upper level is automatically fused, thereby ensuring the business capabilities of the system itself. Figure 2 , 3 , 4, 5, specifically:

[0070] S101: Add, modify or delete existing system fuse rules in the system;

[0071] S102: Obtain system specifications and system cascade relationship;

[0072] S103: Generate the following fuse rules according to the system specifications and system cascade relationship of S102:

[0073] The overall ingress traffic QPS and abnormal ratio fuse rules. QPS stands for query rate per second. QPS can be used to measure the amount of traffic processed by a specific query server within a specified time.

[0074] QPS restriction rules for accessing data interfaces;

[0075] Subscription push interface QPS limit rules;

[0076] QPS restriction rules for the control alarm push interface;

[0077] Cascade query interface QPS limit rules;

[0078] S104: System indicator collection, collecting key indicators such as system memory, CPU, network and the cascade status of upper and lower levels;

[0079] S105: The circuit breaker rules are dynamically changed. The following circuit breaker rules are generated based on the key system indicators collected in S104:

[0080] Subscribe to push interface parameter fuse rules, that is, limit the push of collected data to superiors with abnormal status;

[0081] The control alarm push interface parameter fuse rule limits the push of control alarm data to the superior with abnormal status;

[0082] Cascade query interface parameter fuse rules, that is, limit the query to the data of the lower-level abnormal system;

[0083] S106: convert the parameter fusing rules generated in S103, S103, and S105 into fusing rules that can be recognized by the fusing component and load the rules into the memory;

[0084] S107: When the interface in the system reaches the fuse rule configured in S106, the fuse warning and recording module issues an alarm for the system key indicator warning to remind the user that the system status is abnormal. When sending the fuse, the fuse time, reason and duration, and the cascade data loss during the current fuse time are recorded for the upper and lower data reconciliation function.

[0085] S108: persist the rules of S106 to a persistent device so that they can be used after the system is restarted;

[0086] S109: Send the rule fuse rule of S106 to the cross-service message change notification for other replicas to consume and use the new fuse rule;

[0087] S110: When the system is restarted, the existing fusing rules may be loaded from the data persistence device for use by the fusing component.

[0088] By repeating S103, S104, S105 and S106, automatic protection of the view library system can be achieved according to the status change of the system cascade system.
