Monit is a free and open source process and resource monitoring tool that can be used to monitor system processes and resources using a web browser and command line. Monit automatically stops or restarts processes or services if, for example, they use too many resources or behave abnormally. It also sends email alerts about various events.
On this page, we will perform some fine-tuning on an existing Monit instance (installed and configured by the ISPConfig automated installer) on a Debian 11 (Bullseye) perfect server to make it work properly for us.
