Monit is a utility for managing and monitoring, processes, files, directories and devices 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 to much resources. You can use monit to monitor files, directories and devices for changes, such as timestamp changes, checksum changes or size changes. You can even use monit to monitor remote hosts; monit can ping a remote host and check port connections.
