Monit is a helpful open-source utility that helps you manage and monitor processes, files, directories, and network services on a Linux server. It can be used to ensure that critical services are always running, and can alert you when issues arise.
To install Monit on a Linux server using apt, run the following command: sudo apt install monit
Alternatively, to install it using yum, run: sudo yum install monit
Once Monit is installed, you can start monitoring services and processes by editing the configuration file located at /etc/monit/monitrc and adding the necessary checks. You can also configure alerts to be sent when issues are detected.
For more information on how to use Monit, including advanced configuration options, consult the official documentation.
