Fig. 1 is a schematic diagram illustrating an embodiment of a restart tool for monitoring application states according to the present invention.
In this specific embodiment, the application state monitoring restart tool mainly includes: a configuration module 101, a timing request module 102, and a restart module 103, wherein,
the configuration module 101 is configured to configure path environment variables for the timing request module and the restart module according to at least one application process that needs to be monitored and restarted, and configure a directory of the monitored application processes and a URL interface address of each monitored application process;
the timing request module 102 is configured to execute a curl command according to a predetermined execution cycle, and request, through a URL interface address, to acquire request success return information indicating that a corresponding monitored application process operates normally and request failure return information indicating that a corresponding monitored application process operates abnormally;
and the restarting module 103 is used for restarting the corresponding monitored application process according to the request failure return information.
The application state monitoring restarting tool provided by the invention can realize personalized requirements, solves the problem of monitoring incapability when an application process still exists but the service is suspended and loses response, ensures normal business operation of a client, and further reduces labor cost and operation and maintenance cost.
In a specific embodiment of the present invention, the application state monitoring restart tool is integrated in the monitored application process, and the integrated setting is convenient for integrating with the monitored application process, and the monitored application process is monitored and restarted independently, and there is no need to install components related to the application state monitoring restart tool, etc., which not only is convenient for users to use, but also reduces the maintenance cost.
In the specific embodiment shown in fig. 1, the application state monitoring restart tool of the present invention includes a configuration module 101, configured to configure path environment variables for a timing request module and a restart module according to at least one application process that needs to be monitored and restarted, and configure a directory of the monitored application process and a URL interface address of each monitored application process. The module is configured with the environment and data needed by the timing request function and the restart function in advance, so that the timing request module can smoothly request the URL interface address and smoothly restart the abnormally-operated application process.
Specifically, the method and the device rely on the request result of the URL interface address to judge whether the application process corresponding to the URL interface address is normal, so that the application process is limited to http application, namely website application. In the specific example, assuming that two application processes (application process 1 and application process 2) need to be monitored and restarted, configuring a directory of the monitored application process, and adding the application process 1 and the application process 2 in the monitored application process directory of the application state monitoring and restarting tool; configuring a URL interface address of each monitored application process, wherein each application process corresponds to a unique URL interface address, so that the URL interface addresses corresponding to the application process 1 and the application process 2 are added to an application state monitoring restart tool; and configuring a path environment variable, wherein the environment for calling the script in the crottab file may be inconsistent with the environment variable in the shell, so that data in the path environment variable is modified, the path environment variable is ensured to comprise data related to the application process 1 and the application process 2, a timing task is further added to the timing request module, and smooth execution of the timing task is ensured.
In the specific embodiment shown in fig. 1, the application state monitoring restart tool of the present invention includes a timing request module 102, configured to execute a curl command according to a predetermined execution cycle, and request, through a URL interface address, to obtain request success return information indicating that a corresponding monitored application process operates normally and request failure return information indicating that a corresponding monitored application process operates abnormally. The module requests the URL interface address of the application process so as to obtain whether the monitored application process returns information or not, and further restarts the monitored application process corresponding to the returned information after the request fails, thereby solving the problem of incapability of monitoring when the application process still exists but the service is suspended and loses response.
In one embodiment of the invention, the timing request module includes a timing sub-module for setting a predetermined execution period for executing the curl command using the crontab command. The module uses a common crontab command to set a preset execution period for executing the curl command, and has simple technology and convenient maintenance.
In particular, the crontab command is commonly found in Unix and Unix-like operating systems for setting instructions that are executed periodically. This command reads the curl command and deposits it in the "crontab" file for later reading and execution. Typically, the command stored in the crontab file is activated by the application state monitoring restart tool, and every cycle, it is checked whether there is a predetermined job to be executed. This type of job is commonly referred to as cron jobs.
In this particular embodiment, the predetermined execution period may be set to one minute, i.e., the URL interface address is periodically requested once per minute for executing the curl command.
In a specific example of the present invention, the application process 1 requests, through its URL interface address, to obtain the request success return information indicating that the application process 1 operates normally and the request failure return information indicating that the application process 1 operates abnormally. In practical application, the curl command requests to obtain the return information of the URL interface address once per minute through the HTTP protocol, and if there is no special requirement and modification, the requested URL interface address is expected to return the following character string:
{ "success": message ": no authority, please contact administrator for authorization", "code":500 "," result ": null", "timestamp":1626922477344 "," cost time ":0}
This string indicates that the request is not authorized (not logged in), but does not affect us in determining the application state. If the URL interface address of the application process 1 has a return character string, it indicates that the application process 1 operates normally, and the character string is the return information that the request succeeds, and if the URL interface address of the application process 1 has no return character string, it indicates that the application process 1 operates abnormally, and there is no return character string, i.e., the return information that the request fails.
The request for the application process 2 through the URL interface address thereof obtains the request success return information indicating that the application process 2 operates normally and the request failure return information indicating that the application process 2 operates abnormally, which are the same as the application process 1, and are not described herein again.
In the specific embodiment shown in fig. 1, the application state monitoring restart tool of the present invention includes a restart module 103, configured to restart a corresponding monitored application process according to request failure return information. The module restarts the abnormally-running application process so as to avoid influencing the normal business operation of the application client.
Specifically, the timing request module acquires the return information of the URL interface address once every minute, and if the application process 1 acquires the request return information successfully at the current time, that is, if the application process 1 operates normally at the current time, the application process 1 does not need to be restarted, and if the application process 2 acquires the request failure return information at the current time, that is, if the application process 2 operates abnormally at the current time, the application process 2 needs to be restarted.
In an embodiment of the present invention, referring to the schematic diagram of an embodiment of an application state monitoring restart tool provided in fig. 2 of the present invention, the application state monitoring restart tool further includes a return information recording module, configured to obtain a log record by using request success return information and request failure return information obtained by the timing request module; and the restarting module is used for restarting the corresponding monitored application process if the frequency of requesting the failure return information in the log record is greater than a preset frequency threshold value. The module is convenient for increasing the fault tolerance of the application process, so that the application process is restarted after obtaining the request failure return information for multiple times, the times of executing the restarting operation of the application state monitoring restarting tool are reduced, and the fault caused by frequent operation is avoided.
In an embodiment of the present invention, referring to the schematic diagram of an embodiment of an application status monitoring restart tool provided in fig. 2 of the present invention, the returned information recording module includes a record updating sub-module, configured to, if the returned information of the monitored application process is the request successful returned information, overwrite and refresh the corresponding log record by the request successful returned information; and if the return information of the monitored application process is the request failure return information, adding the request failure return information to the corresponding log record.
Specifically, the return information recording module separately records the return information corresponding to each of the application process 1 and the application process 2 to the log record, and in the process, the Echo redirection technology may be applied to record the request success return information and the request failure return information to the log record, or a print or printf command may be executed to record the request success return information and the request failure return information to the log record, which is not limited in the present invention. During recording, if the return information of the monitored application process is request success return information, the record updating submodule uses the request success return information to cover and refresh the corresponding log record, and if the return information of the monitored application process is request failure return information, the record updating submodule adds the request failure return information to the corresponding log record.
Assuming that the return information which is obtained by the first request of the application process 1 in the log record is the request failure return information, recording the request failure return information to the log record: { application process 1: request failure return information }, the return information obtained by the second request is still the request failure return information, then the request failure return information is added to the log record: { application process 1: request failure return information; request failure return information }, the return information obtained by the third request is request success return information, and the request success return information can cover and refresh the log record of the application process 1, that is, the log record of the application process 1 at the current time is: { application process 1: request successful return message }.
And the restart module judges the times of requesting the failure return information corresponding to the application process, and if the times of requesting the failure return information in the log record are greater than a preset time threshold, the corresponding monitored application process is restarted.
In this embodiment, the number threshold may be set to 3, and it is assumed that the log of the application process 1 at the current time is: { application process 1: request success return information }, the number of times of requesting failure return information in the log record of the application process 1 is 0, which indicates that the current time of the application process is normal and does not need to be restarted, and it is assumed that the log record of the application process 2 at the current time is: { application process 2: request failure return information; request failure return information; request failure return information; request failure return information }, the number of times of requesting the failure return information in the log record of the application process 2 is 4, which is greater than a preset number threshold 3, and it represents that the return information that the application process 2 has been continuously acquired four times is the request failure return information, and since the request is acquired once per minute, that is, the application process 2 has been continuously in an abnormal state for four minutes, the restart module restarts the application process 2.
By applying the application state monitoring restart tool, the invention can realize the personalized requirement, solve the problem of monitoring incapability when the application process still exists but the service is suspended and the response is lost, ensure the normal business operation of the client and further reduce the labor cost and the operation and maintenance cost.
