Although I don’t currently run LibreNMS<\/a> in my own network, it is one of those tools that I keep in my toolbox. LibreNMS is a fork of the Observium<\/a> project. The tool is written in PHP and can be run on any Linux with either Apache or NGINX.<\/p>\n\n\n\n

Setup<\/h4>\n\n\n\n

One of the reasons I like to use LibreNMS is that it is easy to setup. There are step by step instructions to setup a LibreNMS instance on Ubuntu<\/a> and the rest of the LibreNMS documentation is equally simple to use. Once the software is installed, the web interface makes it very easy to add a host to be monitored (or you can use automated discovery<\/a>). Unlike other tools like Nagios<\/a> and Cacti<\/a>, LibreNMS by default creates graphs and pollers for just about every metric you could want on a server or network device. This lowers the setup curve as you don’t have to go into the weeds of SNMP MIBs and OIDs.<\/p>\n\n\n\n

Features<\/h4>\n\n\n\n

Beyond the basic SNMP polling, LibreNMS provides an interface to use Nagios plugins<\/a> to monitor services on hosts. These include things like DNS, DHCP and web servers. These plugins allow you to leverage one of the most powerful features of Nagios without having to work with the complicated configuration of Nagios. <\/p>\n\n\n\n
