Monit is an open-source utility program used to manage and monitor resources and services on Linux systems. Some services and resources managed by Monit are CPU usage, memory usage, server uptime, network connections, and server applications services. It also makes sure that all running services are always healthy by restarting services that stop or encounter errors during operation. These errors and other important events can be automated to send notifications with certain instances or occurrences.
