Monit is a utility for managing and monitoring processes, files, directories and filesystems on a Unix system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations. E.g. Monit can start a process if it does not run, restart a process if it does not respond and stop a process if it uses too much resources. You may use Monit to monitor files, directories and filesystems for changes, such as timestamps changes, checksum changes or size changes.

The monit addon comes with a default configuration file monitrc in /etc.
