Description

Method and device for testing linkmzation performance

Technical Field

The invention relates to the technical field of computers, in particular to a method and a device for testing link performance.

Background

As internet users increase and access peaks due to various special events occur, network services have higher and higher requirements for system performance. Whether the system can bear instant high concurrency and has higher response speed is the key of user experience, so the performance test becomes more important, and the performance test scheme is gradually changed from a single machine test to a cluster test and a link test. The link refers to a data transmission link, for example, application a calls application B, which calls application C, and then data is transmitted from application a to application B to application C, which forms a data transmission link in the system. However, the cost consumption of the link performance test is relatively large, and a set of proprietary test links is usually required to be constructed to complete the communication of the traffic on the whole link, otherwise the test data affects the production data. Thus, online linkability performance testing becomes time consuming and laborious.

The linkability performance test is different from a single cluster test, and needs a cluster service to transmit the flow to a downstream system, so that the performance test effect on the downstream system is also achieved. Often, a critical link associates 4, 5 systems, eventually reaching the persistence layer. Therefore, the difficulty of the link-based test mainly lies in the cooperative work of multiple systems, and one link-based performance test may require the cooperation of tens of people to ensure that the respective systems are configured correctly, and monitor the states of the systems during the test process to ensure that the systems work normally.

The existing link performance test method mainly comprises the following 3 methods:

1. performing a linkability performance test by building a test link, wherein firstly, a machine is used for performing the performance test from an offline part in a production environment; secondly, the grouping is changed by modifying the virtual IP address or other configuration centers; then, modifying the configuration file of the system and restarting the system to connect the upstream and downstream systems; finally, after the test is finished, the environment is recovered;

2. performing a linkability performance test based on a flow identification method, wherein research and development personnel are required to modify a flow code and forward data with a test identifier to a specified downstream system so as to realize the linkability performance test;

3. the linkability performance test is carried out based on an online mirroring method, an environment which is the same as a production environment needs to be copied, and then the test is carried out in the mirroring environment.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:

1. in the above 3 link performance testing methods, each system in the link lacks uniform configuration management, and cannot uniformly monitor the working state of the current testing system;

2. the testing link is built to test the linkability performance, and the process of building the testing link is complex and is easy to make mistakes;

3. when a new test identifier needs to be added, the code needs to be rewritten again, and the process is complicated;

4. the link performance test is carried out based on an on-line mirror image method, a large amount of server resources are occupied, two sets of environments need to be maintained, and the labor and resource cost is wasted.

Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In order to solve the problems in the prior art, the invention provides a link performance testing scheme based on flow isolation, which can improve the efficiency of system performance testing. The method for testing the linkmzation performance uniformly sets the scope of the application to be tested as a test domain through the scope strategy of the network communication framework, thereby realizing the automatic isolation of the test flow and the production flow without configuring and restarting the system to generate a test link; marking of service data and test data is not needed to ensure that the test data does not pollute production data; and the production environment does not need to be copied, and the linkability performance test is carried out based on the online mirror image, so that the time cost for performance test preparation and the server cost are greatly saved. Meanwhile, the method for testing the linkmzation performance of the embodiment of the invention can also carry out unified monitoring on each application system in the test link, ensure the safety of the system and provide a basis for capacity evaluation. In addition, the method for testing the linkmzation performance of the embodiment of the invention is an automatic performance test, reduces manual intervention, prevents human errors, saves labor cost, can execute the on-line linkmzation performance test at any time and realizes the normalization of the performance test.

Companies typically have an internal unified network communication framework, which may be a standard network communication protocol or an encapsulated network communication protocol. By encapsulating the network communication protocol, the data connection between the two parties can be realized in an actual data communication system through different encryption modes of the protocol. Common encapsulated network communication protocols such as remote Procedure call (rpc) (remote Procedure call) framework, etc. Standard network communication protocols such as TCP/IP protocol, IPX/SPX protocol, NetBEUI protocol, etc.

The invention adds scope attribute in the network communication frame for flow isolation, and adds judgment to the scope in the data communication process, only the client and the server of the same scope can carry out data communication, otherwise, the error is reported. And the modification of the scope can be dynamically configured through the management center, so that the application does not need to be restarted. By identifying the scope set in the network communication framework, system research personnel can perform performance test without modifying business logic. The management center is configured to configure and manage all applications, and configuration information related to the applications, such as: scope attributes, IP (Internet Protocol, Protocol for interconnection between networks) addresses of machines deployed by the application, hardware information, and the like.

Fig. 1 is a schematic diagram illustrating an implementation principle of a method for testing link performance according to an embodiment of the present invention. Typically, one application may be deployed in an application cluster consisting of multiple machines, and likewise, more than one application may be deployed on a machine. Therefore, when the scope is set, the attribute value corresponding to the scope attribute includes two parts, namely the application identifier and the identifier of the machine where the application is deployed, and the scope of the corresponding application deployed on the corresponding machine, which is required for testing, is set as the test domain according to the application identifier and the identifier (for example, the IP address) of the machine where the application is deployed. The application identifier may uniquely identify an application, such as an application name or number; the machine identification may uniquely identify a machine, such as the machine's IP address, physical address (MAC address), or machine number.

As shown in FIG. 1, in this embodiment, the test program and the selected scope of the machine on which the application A and the application B are deployed are set to be the same scope (for example, a test scope); the scope of other systems which do not need to be tested, such as the online application and other unselected machines with the application A and the application B, is set to be the same scope (for example, a default domain), so that the test program in the test domain cannot perform data interaction with the application A or the application B in the default domain, and the online application in the default domain cannot perform data interaction with the application A or the application B in the test domain, thereby realizing traffic isolation.

Specifically, when the method for testing the link performance is used for testing the performance, firstly, applications and machine ranges participating in the test are set in a management center, the scope of the application participating in the test is set to be a unified test domain by selecting application identifiers participating in the test under the scope attribute and deploying machine identifiers of the applications, no machine needs to be offline, the applications of other scopes cannot be influenced, and test data cannot enter other scopes; then, performing a linkability performance test according to a set test scheme; and finally, after the performance test is finished, restoring the scope one key of the application and the corresponding machine in the test domain to the previous scope.

According to the technical scheme of the embodiment of the invention, when the linkability performance test is carried out, one test link can be set according to the requirement, and a plurality of test links can be set and the performance test can be carried out simultaneously. When a plurality of test links are required to be used for performance test at the same time, data isolation among the plurality of test links can be realized only by setting the scope of the application and the corresponding machine included in the different test links as different scopes, and the method is convenient, efficient and safe.

Fig. 2 is a schematic diagram of a system architecture for testing linkability performance according to an embodiment of the present invention. The system for testing the linkability can also monitor the test link system in a unified way. As shown in fig. 2, the system for testing linkability performance of the present invention mainly includes a management center, a monitoring center, a performance testing management center, a press, and a testing link composed of applications to be tested, such as application a, application B, and application C.

Through the management center, all application information of the current test link and machine information corresponding to the applications can be obtained in real time. The content of the application information and the Machine information to be acquired can be set by a tester, and the application information includes, but is not limited to, JVM (Java Virtual Machine) disk information, interface TPS (Transaction PerSecond, number of executed transactions per second), interface response time, and the like; the machine information includes, but is not limited to, utilization of a CPU (central processing Unit), a memory, a hard disk, a network, and the like.

Through the monitoring system, the state parameters of the applications and the machines can be collected in real time and fed back to the performance test management center.

The performance test management center can judge whether the test adjustment is needed according to the state threshold value set before the test and the state parameter fed back by the monitoring system. When the state parameter fed back by the monitoring system does not exceed the set state threshold, the test can be continued according to the previous test scheme, and the test adjustment can also be performed to generate a test adjustment task, for example: when step pressurization is carried out, whether the number of concurrent requests is continuously increased or the magnitude of the concurrent requests is increased is judged according to the state parameters fed back by the monitoring system and the set state threshold, if the number of concurrent requests is required to be increased or the magnitude of the concurrent requests is required to be increased, a corresponding test adjustment task is generated and sent to the press machine, and therefore the effectiveness and the safety of step pressurization are guaranteed; when the working state parameter fed back by the monitoring system exceeds the set state threshold value, an alarm can be sent out, test adjustment tasks for stopping the test or reducing the quantity of concurrent requests are generated, and then the generated test adjustment tasks are sent to the press machine to be executed. The set state threshold includes, for example: CPU utilization of 95%, memory utilization of 90%, and so on.

The press is used for generating the simulation test flow according to the test task or the test adjustment task sent by the performance test management center.
