NetBox agent for server

Project description

Netbox agent Build Status

This project aims to create hardware automatically into Netbox based on standard tools (dmidecode, lldpd, parsing /sys/, etc).

The goal is to generate an existing infrastructure on Netbox and have the ability to update it regularly by executing the agent.


  • Create virtual machines, servers, chassis and blade through standard tools (dmidecode)
  • Create physical, bonding and vlan network interfaces with IPs (IPv4 & IPv6)
  • Create IPMI interface if found
  • Create or get existing VLAN and associate it to interfaces
  • Generic ability to guess datacenters and rack location through drivers (cmd and file and custom ones)
  • Update existing Device and Interface
  • Handle blade moving (new slot, new chassis)
  • Automatic cabling (server's interface to switch's interface) using lldp
  • Local inventory using Inventory Item for CPU, RAM, RAID cards, physical disks (behind raid cards)
  • PSUs creation and power consumption reporting (based on vendor's tools)


Known limitations

  • The project is only compatible with Linux. Since it uses ethtool and parses /sys/ directory, it's not compatible with *BSD distributions.
  • Netbox >=2.6.0,<=2.6.2 has a caching problem ; if the cache lifetime is too high, the script can get stale data after modification. We advise to set CACHE_TIME to 0.

Specific workflow


Each vendor class has a is_blade method which is later used for Device creation using the Netbox parent/child feature.

The get_blade_slot method return the name of the Device Bay.

Certain vendors don't report the blade slot in dmidecode, so we can use the slot_location regex feature of the configuration file.

Anycast IP

The default behavior of the agent is to assign an interface to an IP. So two servers with anycasted IPs, running update mode, would only trigger IP's interface assignement in a loop.

In order to handle this case, user need to set Netbox IP's mode to Anycast so that the agent will create another one if it's present on another server.
