Test Status


LibreNMS is an auto-discovering 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.

We intend LibreNMS to be a viable project and community that:

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

The Debian Social Contract will be the basis of our priority system, and mutual respect is the basis of our behavior towards others.


Documentation can be found in the doc directory or docs.librenms.org, including instructions for installing and contributing.


You can participate in the project by:

VM image

You can try LibreNMS by downloading a VM image. Currently, a Ubuntu-based image is supplied and has been tested with VirtualBox.

Download one of the VirtualBox images we have available, documentation is provided which details login credentials and setup details.
