As a network administrator, one of your jobs 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.
In today’s post, we will describe the installation of ManageEngine OpManager on Linux. We will be installing the OpManager on Ubuntu 20.04. However, this method can also be followed for any other Linux distribution.
Note: You will require sudo privileges for the installation and running of ManageEngine OpManager.
