Description
Technical Field
The embodiment of the invention relates to computer technology, in particular to a fusing degradation triggering method, a fusing degradation triggering system and a storage medium.
Background
In large-scale internet applications or high-traffic applications, an application system often uses distributed services to implement functions corresponding to various application services, so that the whole service line flow can be implemented by calling different application services. For example, in the e-commerce field, the whole ordering process often needs to call multiple application services, such as an order service, a third party merchant service, a logistics service, and the like. However, when the upstream application service calls the downstream application service, if the downstream application service has not responded, the upstream application service will always occupy the thread to wait for the response, so that other interfaces or logic of the upstream application service always wait for the release of the thread, and further, the availability of the upstream application service is greatly reduced. And when the upstream application service frequently and repeatedly calls the downstream application service all the time, the application thread of the downstream application service is occupied by the frequent calling of the upstream application service, so that the downstream application service cannot provide stable and available services for other services.
Aiming at the problem, the fusing degradation mode is set for each application service for processing, such as a thread pool isolation mode, so that the usability and the stability of each application service are improved, the flexible availability of a system is ensured, and the avalanche effect is avoided. In the prior art, an open source component Hystrix of Netflix is generally sampled for performing thread pool isolation demotion. In the Hystrix framework, an application service is preset to be a thread pool isolation mode, for example, two independent thread pools are respectively set for a placing sub-service and an order inquiring sub-service in a transaction service, so that different sub-services use different thread pools, and mutual influence of threads is avoided.
However, in the process of implementing the present invention, the inventor finds that at least the following problems exist in the prior art:
because the existing thread pool isolation mode is to perform thread pool isolation degradation before the server runs, unnecessary thread pool isolation degradation is also required when the server has good performance, which causes resource waste and reduces the resource utilization rate.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for triggering fusing degradation according to an embodiment of the present invention, where the embodiment is applicable to automatically triggering a fusing degradation operation in a service server. The method can be executed by a fusing degradation triggering device, which can be implemented by software and/or hardware, and is integrated in a management and control server. The method specifically comprises the following steps:
s110, the management and control server obtains performance parameter information of each service server in the service server cluster corresponding to the application service.
The application service may refer to any service function in a service line flow for implementing a certain application service. The service server cluster may be composed of a plurality of service servers executing application services, where each service server is loaded with a service system corresponding to a corresponding application service to independently implement a function of the corresponding application service. In this embodiment, a plurality of application services may be provided, and each application service may be stored in a distributed manner, that is, each application service corresponds to an independent service server cluster, so that each service server cluster is used to execute a function of a corresponding application service, thereby implementing a distributed service. The performance parameter information may refer to parameters for measuring performance indexes of the service server in a running process and application service dimensions, and may include, but is not limited to, a CPU (Central Processing Unit) usage rate, a memory usage rate, a QPS (Query Per Second, Query rate Per Second), a call success rate, a call failure rate, and an access frequency. The management and control server may refer to a server for managing and monitoring each service server. The number of the management and control servers in this embodiment may be one or more, so as to efficiently manage and control the service server clusters corresponding to all the application services.
Specifically, in this embodiment, the service server cluster corresponding to each application service to be controlled may be connected to the control server in advance, so that the control server may obtain the performance parameter information of each service server. Illustratively, the performance parameter information may be obtained by the management and control server periodically reporting or pulling the performance parameter information of the service server through a Remote Procedure Call (RPC) interface or an HTTP (HyperText Transfer Protocol) interface provided by each service server; or each service server and the control server are in Socket network connection, so that the control server obtains the performance parameter information; the service server may also send an mq (message queue) message notification to the management and control server, so that the management and control server obtains the performance parameter information of each service server; the service server may also print log data in a preset format, and the management and control server obtains the performance parameter information by scanning the log data.
It should be noted that, a developed tool jar package may be preset in the service server, a cut plane is configured, and parameters of application service dimensions, such as QPS, invocation success rate, invocation failure rate, access frequency, and the like, are obtained by the tool jar through cut plane statistics.
And S120, generating a target fusing degradation triggering instruction corresponding to the service server by the management and control server according to the preset fusing degradation configuration information and the performance parameter information corresponding to the application service.
The preset fusing degradation configuration information may refer to performance conditions that are met when fusing operation or degradation operation is performed according to business side requirements and application scenarios and configured in advance. And each application service corresponds to preset fusing degradation configuration information one by one. The fusing operation may refer to a self-protection mechanism of the service server, and stops executing the operation or providing the service when an abnormal condition occurs, for example, the result obtained by calling the downstream application service each time the upstream application service calls is a call failure, at this time, the upstream application service does not continue to call the downstream application service, and continues to execute subsequent flow operations based on an alternative scheme, so that flexible availability of the application service is ensured by calling and fusing the upstream application service. The downgrading operation may refer to processing by using an alternative scheme in the case of an abnormal condition to ensure the availability of the server, for example, when a plurality of upstream application services frequently call a certain function module of a downstream application service, the uniformly used thread pool may be isolated into a plurality of sub-thread pools corresponding to each function module to ensure normal operation of other function modules without affecting each other, so as to implement isolation and downgrading of the thread pools. The preset fusing downgrade configuration information may include, but is not limited to, fusing configuration information, thread pool isolation configuration information, and access throttling configuration information. The target fusing downgrade trigger instruction may refer to an instruction for triggering a business server to perform a fusing operation and/or a downgrade operation. The target fuse destage trigger instruction may be, but is not limited to, a fuse trigger instruction, a thread pool isolation trigger instruction, an access current limit destage trigger instruction, and a timeout time change trigger instruction.
Specifically, when the management and control server obtains the performance parameter information corresponding to each service server, the obtained performance parameter information may be stored in a persistent database so as to calculate each performance index, and according to preset fusing degradation configuration information corresponding to the application service, it is determined whether the performance index of each service server meets a fusing degradation condition, if so, it indicates that the service server needs fusing degradation to ensure the flexibility of the service server to be available, and at this time, a corresponding target fusing degradation trigger instruction may be generated based on the met fusing degradation mode.
It should be noted that, in this embodiment, performance parameter information of the service server is obtained by the external device, which is a management and control server, so that the CPU usage rate, the memory usage rate, and the call success rate of the service server can be obtained through monitoring, and whether the service server needs to satisfy the thread pool isolation condition can be monitored in real time based on the CPU usage rate, the memory usage rate, and the call success rate. For example, the CPU utilization rate, the memory utilization rate, and the call success rate may be subjected to weighted summation, and whether the addition result is greater than or equal to a preset isolation threshold is detected, and if not, it is determined that the thread pool isolation condition is not satisfied, and at this time, the service server may perform normal processing without performing thread pool isolation operation; if yes, a thread pool isolation triggering instruction can be generated at the moment to automatically trigger the service server to perform thread pool isolation operation, so that the performance of the service server can be monitored in real time, thread pool isolation operation is performed when the performance is reduced to a certain degree, thread pool isolation is not required to be configured in advance, resource waste is avoided, and the resource utilization rate is greatly improved.
S130, the management and control server sends a target fusing degradation triggering instruction to trigger the business server to execute fusing degradation operation corresponding to the target fusing degradation triggering instruction.
The fusing destage operations may include, but are not limited to, a fusing operation, a thread pool isolation operation, an access throttling destage operation, and a timeout time change operation, among others. The access throttling downgrade operation can be to deny access, directly return access success or failure information, or prompt too many response requests, etc.
Specifically, the management and control server may send the target fusing degradation triggering instruction to a service server that needs to perform the fusing degradation operation, and when receiving the target fusing degradation triggering instruction, the service server may automatically trigger and execute a fusing degradation operation that is configured in advance and corresponds to the target fusing degradation triggering instruction. It should be noted that each service server needs to pre-configure a fusing downgrade code corresponding to each fusing downgrade mode, so that a corresponding fusing downgrade operation can be automatically executed when a trigger instruction is received. Illustratively, the service server may inherit the thread pool isolation tool class in advance, and the tool class may be uniformly developed into a JAR (Java Archive) package, and only needs to be implemented, and does not need to be repeatedly developed. When the service server detects the thread pool isolation triggering instruction, the thread pool isolation tool can automatically trigger the thread pool isolation processing, so that the flexibility and the availability of the service server are ensured.
In the technical scheme of this embodiment, an additional management and control server is set to monitor performance parameter information of each service server in a service server cluster, and determine whether the service server needs to perform a fusing downgrading operation according to preconfigured preset fusing downgrading configuration information and acquired performance parameter information, if so, a target fusing downgrading trigger instruction corresponding to the service server is generated, and the target fusing downgrading trigger instruction is sent to the service server, so that when the service server receives the target fusing downgrading trigger instruction, the fusing downgrading operation corresponding to the target fusing downgrading trigger instruction, such as a thread pool isolation downgrading operation, can be automatically triggered and executed, without presetting, avoiding executing unnecessary fusing downgrading operation, greatly improving the resource utilization rate.
On the basis of the above technical solution, S120 may include: and the management and control server generates a target fusing degradation triggering instruction corresponding to the service server according to preset fusing degradation configuration information and performance parameter information corresponding to the application service stored by the coordination server. Accordingly, S130 may include: and the management and control server stores the target fusing degradation triggering instruction to a target position corresponding to the application service in the coordination server, so that each service server executes fusing degradation operation corresponding to the target fusing degradation triggering instruction when detecting that the target fusing degradation triggering instruction is stored in the target position.
The coordination server may be a server that stores preset fusing degradation configuration information and a target fusing degradation trigger instruction corresponding to each application service based on a preset data storage structure. FIG. 2 illustrates an example of a fuse-degraded triggering framework. The coordination server may store, based on the preset data storage structure in fig. 2, preset fusing degradation configuration information and a target fusing degradation trigger instruction corresponding to each application service appName. Each service server can establish connection communication with the coordination server in advance so that whether the content in the coordination server changes can be monitored in real time. In this embodiment, one or more coordination servers may be provided to automatically avoid the single-point problem, that is, when an abnormal condition exists in a currently used coordination server, the currently used coordination server may be automatically switched to another coordination server. Illustratively, the coordinating server may be a server that employs Zookeeper coordination service technology. The Zookeeper coordination service technology is an open source distributed application program coordination service, and can provide a consistency service function for distributed applications, such as functions of distributed coordination/notification, configuration maintenance, distributed locks, distributed queues and the like.
Specifically, in the embodiment, by storing the preset fusing degradation configuration information corresponding to each application service in the coordination server, each management and control server can obtain uniform configuration information from the coordination server, and accurate management and control of each management and control server are ensured. The target fusing degradation triggering instruction is stored to the target position in the coordination server, and the business server monitors whether the target fusing degradation triggering instruction is stored in the target position in real time, so that triggering and execution of fusing degradation can be controlled more conveniently, and stability of the system is improved.
On the basis of the above technical solution, before S110, the method may further include: the method comprises the steps that a control server obtains preset fusing degradation configuration information corresponding to application services; the control server controls the coordination server to create a configuration information storage node and a trigger information storage node corresponding to the application service, and stores preset fusing degradation configuration information into the configuration information storage node; the trigger information storage node comprises a plurality of first trigger sub-nodes; the first trigger sub-node is created by the service server controlling the coordination server when starting, and is used for storing the IP address of the service server.
Specifically, when there is an application service to be controlled, the application service needs to be applied to access to the control server in advance, so that the control server can control the application service. For example, a service party may input information of an application service to be managed in a platform page of a management and control server, such as preset fusing degradation configuration information; after the auditor passes the audit, an application service identifier appName can be automatically allocated to the application service so as to distinguish different application services, and the coordination server is controlled to create a configuration information storage node and a trigger information storage node corresponding to the application service so as to store the configuration information of the application service and the subsequently generated trigger information. After the service server is started, the service server can communicate with the coordination server, so that the coordination server can be controlled to create a first trigger sub-node corresponding to the service server in a trigger information storage node, the IP address of the service server is stored by using the first trigger sub-node, registration of the service server is achieved, the management and control server can monitor performance of each service server based on the stored IP address, and the service server can also monitor content change in the coordination server in real time. Each service server corresponds to a first trigger sub-node.
Illustratively, the preset fusing degradation configuration information may include at least one of fusing configuration information, thread pool isolation configuration information, and access throttling configuration information; the configuration information storage nodes comprise a first configuration sub-node, a second configuration sub-node and a third configuration sub-node; correspondingly, storing the preset fusing degradation configuration information into the configuration information storage node comprises the following steps: storing the fusing configuration information corresponding to the application service into a first configuration sub-node; storing the thread pool isolation configuration information corresponding to the application service into a second configuration sub-node; and storing the access current limiting configuration information corresponding to the application service into a third configuration sub-node.
Specifically, fig. 3 shows an example of a data storage structure of a collaboration server. Fig. 3 is a logical schematic of the data storage structure referred to in fig. 2. After an application service is accessed to the management and control server, the management and control server can automatically create a configuration information storage node/app/config/$ { appName } and a trigger information storage node/app/server/$ { appName } corresponding to the application service. When a service party configures the application service based on a service requirement, that is, obtains preset fusing degradation configuration information corresponding to the application service, a first configuration sub-node/app/config/$ { appName }/serviceTime, a second configuration sub-node/app/config/$ { appName }/threadedpool, and a third configuration sub-node/app/config/$ { appName }/limitConfig in a configuration information storage node may be created to store fusing configuration information, thread pool isolation configuration information, and access current limiting configuration information in the preset fusing configuration information, respectively, and if only one configuration information exists, other configuration sub-nodes may be stored as empty. When the service server is started, the coordination server may be controlled to create a corresponding first trigger sub-node/app/server/$ { appName }/$ { IP } in the trigger information storage node, so as to store the IP address of the service server by using the first trigger sub-node. The trigger sub-node and the second trigger sub-node in fig. 3 are used for storing fuse degradation trigger instructions corresponding to different fuse degradation modes. It should be noted that the/app/config node in fig. 3 may be used to store common configuration information of the application service. The/app/server node may be configured to store common information of a service server cluster to which the application service corresponds.
Example two
Fig. 4 is a flowchart of a fusing degradation triggering method according to a second embodiment of the present invention, and this embodiment describes in detail a generation process of a target fusing degradation triggering instruction based on the above embodiments. Wherein explanations of the same or corresponding terms as those of the above-described embodiments are omitted.
Referring to fig. 4, the method for triggering fusing degradation provided in this embodiment specifically includes the following steps:
s210, the management and control server obtains performance parameter information of each service server in the service server cluster corresponding to the application service.
S220, the management and control server determines index values corresponding to each fusing degradation mode according to the performance parameter information of each service server.
The fusing downgrades may include, but are not limited to, a thread pool isolation downgrade, a timeout fusing downgrade, and an access current limiting downgrade. The overtime fusing mode can comprise an overtime time changing mode and a direct fusing mode. The index value may be a reference value for reflecting some aspect of the performance of the service server.
Specifically, according to the fusing degradation condition corresponding to each fusing degradation mode, an index value corresponding to each fusing degradation mode can be determined based on the obtained performance parameter information, so that whether the corresponding fusing degradation condition is met or not can be determined by using the index value.
Illustratively, S220 may include: the management and control server determines a first index value corresponding to each service server in a thread pool isolation degradation mode according to the CPU utilization rate, the memory utilization rate and the call success rate of the central server of each service server; the management and control server counts the call failure rate of each service server and determines a second index value corresponding to the overtime fusing mode; and the management and control server counts the access frequency of each service server and determines a third index value corresponding to the access current-limiting degradation mode.
Specifically, for the thread pool isolation degradation mode, a first index value corresponding to each service server needs to be calculated, that is, the CPU utilization, the memory utilization, and the call success rate of the service server may be weighted and summed, and the summed result is determined as the first index value corresponding to the service server. For the overtime fusing mode, the call failure rate corresponding to each service server may be added for statistics, and the addition result is determined as the second index value, so that the overtime fusing operation is performed on all the service servers synchronously by using the second index value. For the access throttling and degrading mode, the access frequencies corresponding to each service server may be added, and the addition result may be determined as a third index value, so that the access throttling and degrading operation is performed on all the service servers synchronously by using the third index value.
It should be noted that, since the management and control server can obtain performance parameters such as the call failure rate and the access frequency of each service server, statistical analysis can be performed on the performance of all service servers, so as to perform the overtime fusing operation and the access current limiting degradation operation on all service servers synchronously.
It should be noted that, in this embodiment, the second index value and the third index value may be determined for the call failure rate and the access frequency of all callers, so as to perform the fusing destage operation on all callers at the same time; or may be determined for a particular caller such that the fuse destage operation is performed only for that particular caller. Illustratively, when a plurality of callers exist in an interface in the service server for calling, a token may be allocated to each caller in advance, and the allocated token needs to be carried during calling, so that different callers may be distinguished based on the token, a call failure rate or an access frequency of each caller is calculated, and a second index value and a third index value corresponding to each caller are counted. For example, in this embodiment, different callers may also be distinguished based on the IP address of each caller, so as to calculate the second index value and the third index value corresponding to each caller, thereby achieving the technical effect that only a certain caller is subjected to fusing degradation, and other callers may call normally.
And S230, the management and control server determines at least one target fusing degradation mode corresponding to the application service according to preset threshold configuration information and index values corresponding to each fusing degradation mode stored by the coordination server, and generates a corresponding target fusing degradation trigger instruction according to the target fusing degradation mode.
The target fusing degradation mode can be one or more, and the specific number of the target fusing degradation modes can be determined based on the number of the fusing degradation conditions which are met. The embodiment can compare the preset threshold configuration information corresponding to each fusing degradation mode with the corresponding index value, so that at least one target fusing degradation mode meeting the configuration conditions can be determined.
Exemplarily, the determining, by the management and control server in S230, at least one target fusing degradation mode corresponding to the application service according to the preset threshold configuration information and the index value corresponding to each fusing degradation mode stored by the coordination server may include: if the first index value corresponding to the target service server is greater than or equal to the preset isolation threshold value, determining that the target fusing degradation mode corresponding to the application service comprises a thread pool isolation degradation mode aiming at the target service server; if the second index value is larger than or equal to the preset fusing threshold value, determining that the target fusing degradation mode comprises a fusing mode; if the second index value is smaller than the preset fusing threshold value, determining that the target fusing degradation mode comprises an overtime time changing mode, and determining the changed target overtime time according to the second index value and a second index value range corresponding to each preset overtime time; and if the third index value is greater than or equal to the preset current limiting threshold value, determining that the target fusing degradation mode comprises an access current limiting degradation mode.
Specifically, when the second index value is smaller than the preset fusing threshold, it indicates that the timeout time that the caller waits may be short, that is, the second index value may be degraded by increasing the timeout time without directly performing fusing operation, and at this time, the preset timeout time corresponding to the currently calculated second index value may be determined based on the second index value range corresponding to each preset timeout time that is configured in advance, and the preset timeout time is used as the target timeout time after the change. It should be noted that the larger the preset timeout time is, the smaller the second indicator value is terminated in the corresponding second indicator value range, so that the larger the second indicator value is, the smaller the preset timeout time is, thereby implementing flexible configuration of the timeout time.
After determining at least one target fusing manner, if the target fusing degradation manner includes a thread pool isolation degradation manner for a target service server, a target thread pool isolation degradation trigger instruction for the target service server is generated. And if the target fusing degradation mode comprises a fusing mode, an overtime time changing mode or an access current limiting degradation mode, respectively generating fusing trigger instructions, overtime time changing trigger instructions or access current limiting degradation trigger instructions for all the service servers.
S240, the management and control server stores the target fusing degradation triggering instruction to a target position corresponding to the application service in the coordination server, so that when the target fusing degradation triggering instruction is stored in the target position, each service server executes fusing degradation operation corresponding to the target fusing degradation triggering instruction.
For example, the step of the step S240 of storing, by the management and control server, the target fusing degradation triggering instruction to the target location corresponding to the application service in the coordination server may include: if the target fusing degradation triggering instruction is a thread pool isolation triggering instruction for the target service server, the management and control server controls the coordination server to create a triggering sub-node in a target first triggering sub-node corresponding to the target service server, and stores the thread pool isolation triggering instruction into the triggering sub-node; if the target fusing degradation triggering instruction is a fusing triggering instruction, a timeout time change triggering instruction or an access current limiting degradation triggering instruction, the management and control server controls the coordination server to create second triggering sub-nodes corresponding to the service servers in the triggering information storage nodes and stores the target fusing degradation triggering instruction into the second triggering sub-nodes.
As shown in fig. 3, if a thread pool isolation operation needs to be performed on a target service server, a trigger sub-node/app/server/$ { appName }/$ { ip }/threadPool may be created in real time in a target first trigger sub-node corresponding to the target service server, and the trigger sub-node is used as a target location to store a thread pool isolation trigger instruction, so that when the target service server monitors that the thread pool isolation trigger instruction is stored at the target location, the target service server may trigger execution of a thread pool isolation operation built in itself.
