Scheduled Files are used to monitor background running programs or server applications, aiming to ensure their stable operation.
Why use 【Scheduled Files】
It is difficult to detect if a background process has issues in its execution, and it is hard to define if a program crashes.
By embedding a function in the program to send out messages at fixed intervals or within a loop, it becomes easier to determine if the program has crashed.
Through the following mechanisms, Scheduled Files provide a real-time operation health indicator:
➢ Require the application to report the file name to the host at fixed time intervals.
➢ If the application fails to report within the specified time, the system will identify it as an anomaly.
➢ When an anomaly occurs, the system will alert the administrator via SMS, email, or other communication methods, prompting them to take necessary measures promptly.
In practice, users need to download Watchdog's dedicated program 【wdogc_ftmsks】 on the client side.
This program can be embedded in the user's desired monitoring program to periodically report the specified file name to the Watchdog host.
If the host does not receive the required file name within the set time, it will recognize the user program as crashed and immediately issue an alert.
Understanding the basic concept of 【Scheduled Files】 is relatively straightforward, but setting and applying it requires more effort to understand.
