Monit

Monit is an open-source utility used for monitoring and managing Unix systems. It provides proactive monitoring of system resources, services, and processes, allowing administrators to detect and respond to issues before they impact system performance or availability.

Features of Monit:

• Monit can monitor the status of running processes and restart them automatically if they fail or consume excessive resources.
• It monitors CPU usage, memory usage, disk space, and other system resources, alerting administrators of potential issues or resource constraints.
• Monit can monitor network services such as web servers, databases, and email servers, ensuring they are running and responding as expected.
• Monit provides a web-based interface for monitoring system status, viewing alerts, and configuring monitoring settings.

To get the login details and to start web service, run the following command on your VM:
$ sudo su $ cd /opt $ monit --version $ systemctl restart monit
