Process monitoring with Python and Telegram
Practical Example
Launch the script from the terminal with the following syntax:
python crashinspector.py token:user_id process_name interval
where token is the token provided by BotFather, user_ID is the Telegram user ID provided by the Get Chat ID bot, process_name is the name of the process you are monitoring, and interval is the time interval for performing the checks (in minutes). For example, run the following command to check the status of the filezilla process every 30 minutes:
python crashinspector.py 7237372881:AAEA-ZPF9WMRX5aNSa0PoJDCiUePoNqu0Uk 17130319 filezilla 30
Assuming that filezilla is terminated after about two and a half hours, the output will be similar to Listing 3.
Listing 3
Output
filezilla up and running at 2024-07-21 16:49:13.559405 filezilla up and running at 2024-07-21 17:19:13.616971 filezilla up and running at 2024-07-21 17:49:13.621785 filezilla up and running at 2024-07-21 18:19:13.624988 filezilla up and running at 2024-07-21 18:49:13.628092 Process filezilla is currently down
Conclusion
When launched from the console, the script described in this article obtains the list of running processes and checks for an instance of the process. If an instance of the process is active, a string indicating the date and time of the check is printed. The cycle continues in the same manner for the specified time interval. If the process is not running during an iteration of the cycle, the application prints a warning on the console and sends an alert message via Telegram.
