netbox-librenms-plugin 0.3.13

Netbox plugin to sync data between LibreNMS and Netbox.

NetBox LibreNMS Plugin

The NetBox LibreNMS Plugin enables integration between NetBox and LibreNMS, allowing you to leverage data from both systems. NetBox remains the Source of Truth (SoT) for you network, but this plugin allows you to easily onboard device objects from existing data in LibreNMS. The plugin does not automatically create objects in NetBox to ensure only verified data is used to populate NetBox.

Features

The plugin offers the following key features:

Interface Sync

Pull interface data from Devices and Virtual Machines from LibreNMS into NetBox. The following interface attributes are synchronized:

• Name
• Description
• Status (Enabled/Disabled)
• Type (with custom mapping support)
• Speed
• MTU
• MAC Address

Set custom mappings for interface types to ensure that the correct interface type is used when syncing from LibreNMS to NetBox.

Cable Sync

Create cable connection in NetBox from LibreNMS links data.

IP Address Sync

Create IP address in NetBox from LibreNMS device IP data.

Add device to LibreNMS from Netbox

• Add device to LibreNMS from Netbox device page. SNMP v2c and v3 are supported.

Site & Location Synchronization

The plugin also supports synchronizing NetBox Sites with LibreNMS locations:

• Compare NetBox sites to LibreNMS location data
• Create LibreNMS locations to match NetBox sites
• Update existing LibreNMS locations langitude and longitude values based on NetBox data
• Sync device site to LibreNMS location

Contributing

There's more to do! Coding is not my day job. Bugs will exist and imporvements will be needed. Contributions are very welcome! I've got more ideas for new features and imporvements but please contribute if you can!
