How To Install OpenNMS Network Monitoring on Ubuntu 14.04 LTS from Scratch
In this video I show you how to install OpenNMS network monitoring software on Ubuntu 14.04 LTS Linux. OpenNMS is a network monitoring software, which allows you to monitor network devices and servers. It also allow for resource monitoring and outage monitoring with escalations thru emails and other alerts.
I show you how to install the Ubuntu so if you have already installed it you can skip ahead to 12:04. I will show you in this video how to install Ubuntu 14.04 for the installation of OpenNMS. In the video I use the DHCP address given to me by my internal DHCP server, you will want to set a static IP address via this link https://help.ubuntu.com/lts/serverguide/network-configuration.html. I also instruct you how to install the complete package for OpenNMS, starting at 12:04. This includes the installation of: PostgreSQL, Oracle Java 1.7, the OpenNMS package, and htop for monitoring the server’s memory and CPU. All of the installations used for this video, can be found here http://www.opennms.org/wiki/Installation:Debian and https://github.com/gregs1104/pgtune.
