Monitoring with Icinga 2

When there is an outage or the system is in a critical status, for example, if the server is overloaded, we need a way to get notified.

Icinga 2 is a great fit for this purpose. It is an open source monitoring system. It uses monitoring plugins to check various services' statuses and generates performance data for reporting. Each plugin is a standalone command-line tool that performs a specific type of check. There are more than fifty standard plugins available on https://www.monitoring-plugins.org.
