LibreNMS and Oxidized Network Ops Stack on Ubuntu 24.04

Overview

LibreNMS is an auto discovering network monitoring system. Point it at a switch, router, firewall, server or PDU and it finds the interfaces, sensors and services itself, keeps the history and draws the graphs, covering interface throughput and errors, BGP and OSPF sessions, VLANs, wireless clients, temperature and power across several hundred device families. Oxidized is its natural counterpart: it logs into each device, retrieves the running configuration and commits it to a git repository, so every change is visible as a diff and any previous version can be restored.

This is the pair run as one product rather than two. Oxidized takes its entire device list from the LibreNMS API, so the devices you already monitor are the devices that get backed up and there is no second inventory to keep in step. In the other direction LibreNMS reads from Oxidized, so each device's stored configuration and its full version history appear on that device's Config tab in the monitoring interface. You add a device once, in one place, and both jobs start.

Common uses

• Monitor switches, routers, firewalls and servers with auto discovery and alerting
• Keep a git versioned backup of every device configuration and diff what changed
• Run monitoring and configuration backup from one device inventory and one interface
