Install Monit Service Monitoring on CWP

Monit is a lightweight open-source utility designed for monitoring and managing Unix systems. It provides automatic and proactive monitoring of various system resources, processes, and services, allowing administrators to detect and address issues promptly. Monit can monitor parameters such as CPU usage, memory, disk space, and system processes, and it can take predefined actions in response to specified conditions, such as restarting a service or sending alerts. Its simplicity and flexibility make it a valuable tool for ensuring the stability, performance, and reliability of servers, contributing to effective system administration and maintenance.

There are times when Monit Service Monitoring may need to be installed on a CWP server to allow Process Monitoring to be enabled. We will cover the Monit installation process in this guide.
