Introduction

LibreNMS is an autodiscovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and many more.

LibreNMS is a community-based fork of the last GPL-licensed version of Observium. LibreNMS intends to be a viable network monitoring project and community that:

• encourages contribution,
• focuses on the needs of its users, and
• offers a welcoming, friendly environment for everyone.

If you're visiting because of a mention on the Observium mailing list, please read our welcome to Observium users.

The Debian Social Contract will be the basis of our priority system, and mutual respect the basis of our behaviour towards others. For more about the culture we're trying to build, please read the Freenode philosophy, including guidelines for running an IRC channel and being a community catalyst.

Documentation

For now documentation can be found in the doc directory.

Try It

You can try LibreNMS by downloading a VM image. Currently, a Debian-based image is supplied and has been tested with VMware Fusion 5.

Download the VMware Fusion 5 image at open it, and log in as root with the password root. Enter the following commands:

cd /opt/librenms
git pull
php discover.php -h all
php poller.php -h all

You'll then need to find out the IP of your VM (ifconfig | grep add) and create a DNS entry for librenms.example.com to point to that IP. You can also edit your /etc/hosts file with the following line:

$ip librenms.example.com

where $ip is the IP of your VM. From there, just point your web browser to http://librenms.example.com/ and login with username librenms and password librenms.
