Install the ManageEngine OpManager on Ubuntu 20.04 - Step by step guide ?

One very important task of a Linux Administrator is to monitor your network closely to ensure everything is working fine and to identify potential issues that can later affect operations. Monitoring also helps you to identify the root cause of the issues and eliminate them before they affect operations. There are several tools available for network monitoring. One such tool is OpManager from ManageEngine. OpManager can monitor any network device including servers, switches, routers, printers, WLAN controllers, VMs, firewalls, etc. It covers nearly all of the aspects of network monitoring like host discovery, physical and virtual server monitoring, network devices monitoring, alerting, customizable Dashboards, etc.
