Description

Application performance management system that measures application connection speed

The present invention relates to a method for invalidating an HTTP cache for application service performance management, and more specifically, a conventional HTTP application service is a file stored in an internal cache memory rather than a server by a user who revisits using an HTTP cache technology. However, the present invention creates an environment in which the user terminal visiting for the first time accesses the application by invalidating the HTTP cache storage operation for measuring performance from the perspective of the user who does not use the application for the first time or frequently. It relates to a method for measuring and managing the connection performance of an application using HTTP such as an app service.

The conventional HTTP cache stores a copy of the file in a specific location at the first request for a resource constituting a web or mobile app such as html, image, js, css, etc. that the client requests, and then requests for the same resource It is a technology that provides faster service by using the saved file without downloading it from the server again. Through this, the content can be used even when offline, and the file is not downloaded from the server again, and the locally stored file is used, enabling much faster speed and data traffic reduction, and reducing the server load required for file transfer. have.

The application service using the HTTP is an application server that provides a service, and a cache for fast deception by storing applications and files such as browsers, mobile apps, etc. mounted on terminals and terminals such as PCs and smartphones. It is composed. When the cache memory is empty, when an application requests a file as an HTTP request signal to use the application service, the server responds by including the cache policy for the file in the header of the HTTP response signal when the file is in the server. The application downloads the actual file data according to the cache policy in the response header and stores it in the internal cache memory. In the case of a user who accesses the application service for the first time or rarely accesses it, the cache memory is emptied.

In addition, when revisiting while the cache memory is full, the application requests the server by including the cache validation information in the HTTP request signal header to check the validity of the file in the internal cache memory. If it is valid, the response is made by including the validity (304 Not Modified) information of the file and the cache policy (Cache-Control, ETag field) in the HTTP response signal header. The application client receiving the response still uses the cache stored in the cache memory without updating the newly received cache policy in the cache memory and downloading the data corresponding to the actual file contents, because the file stored in the existing cache memory is still valid. In the case of a user who frequently uses the application service, the cache memory is always full, so this process is followed.

In recent years, the performance management method of application service has been changed to the service performance standard experienced by real users from the perspective of existing service providers, and for this, a method of measuring and managing performance by repeatedly accessing application services like a real user through a real terminal Is used. In the case of such a repetitive connection, since the connection is made while the cache is full after the initial connection, it is a performance from a user's point of view that frequently uses the corresponding application service. The performance of the application service needs to be managed by dividing it into the first or rarely accessed user's point of view in addition to the frequently used user's point of view, but in the case of performance measurement through repetitive access for performance management in the conventional manner, it is often due to caching There is a problem that can only measure the performance from the perspective of the user to use.

Users who frequently visit the application service can access at a high speed due to the filled cache memory, but users who visit first or rarely will access at a low speed due to the empty cache memory, which eventually leads to the user's departure. . Therefore, in terms of service performance management, it is more important to manage from the perspective of the first or rarely visited user than the frequently used user perspective.

In order to solve the above problems, a method of forcibly emptying and measuring the cache memory every time during repetitive measurement has been conventionally used for service performance management from the perspective of a user who first or rarely accesses. However, in the case of a web application accessed through a browser, the cache memory folder of the browser is fixed, so it is possible to forcibly delete and access through the program.However, if each application has a different cache memory folder location, such as a mobile app, it is used as a program. Difficult to automate. Moreover, in the case of a mobile app application, access to or deletion of the cache memory folder is restricted for security reasons, and thus cannot be solved by forcing the cache memory to be empty.

The present invention is to solve the above-described problem, the present invention is to delete or manipulate the cache-related fields of the HTTP request and response headers that control the storage operation of the cache, instead of deleting the cache stored in the cache memory, the application client The purpose is to prevent the cache storage from being performed fundamentally.

In addition, the present invention is equipped with a performance management agent to repeatedly measure the performance, such as page load time while driving the application client, the performance management agent provides a cache unused measurement mode or cache usage measurement mode according to each performance measurement mode We want to provide a method for invalidating HTTP cache for application service performance management that can measure the sensational performance of users who visit cached memory for the first time or rarely, or users who visit cached frequently.

The connection speed is measured according to the use of.

In addition, as the driving cycle and driving frequency of the application are stored in the scheduler, the driving unit transmits a driving command to the application according to the driving cycle and driving frequency stored in the scheduler.

When the cache-free measurement mode is selected and executed, the modulator intercepts the HTTP response signal transmitted from the server to the application, deletes or modulates the cache-related control statement included in the HTTP response signal, and stores the file in the cache memory. By preventing storage, the speed at which the application is accessed in a cache-free state is measured.

In addition, the performance measurement unit is a performance management agent that separately manages the cache performance measurement value measured in accordance with the selection of the cache usage measurement mode and the cache usage measurement mode and the cache usage performance measurement value measured in the cache usage measurement mode; It is provided.
