Reliability is a crucial aspect of a computer system, especially for servers. Because continuous active monitoring isn't feasible, implementing mechanisms to alert the system administrator in case of a malfunction can be very useful. This article explores how to develop a simple tool that monitors the status of a process and sends a Telegram message in the event of a crash.
Prerequisites
To follow the development of this project, you'll need an integrated development environment enabled for Python programming and some basic knowledge of the Python language. On Ubuntu, it is possible to download VS Code from the App Center by simply finding the VS Code page in the App Center and clicking the Install button. If you prefer to proceed with the installation via the command line, the VS Code documentation provides all the necessary details for completing the procedure on various distributions [1]. I recommend installing the Pylance, Python, and Python Debugger extensions to make development easier. Simply click on the extensions button (on the left side), select the extension, and proceed with the installation.
In addition, you will need a Telegram account and the Telegram messaging application [2] installed on a smartphone or PC. For Ubuntu users, the application is available on the Snapstore. From the command line, you can install it with apt using the command
