Agent database


The agent database is located in agent data directory. It consist of the following files:

  • pci.ids is a database of PCI devices, used by local inventory module
  • usb.ids is a database of USB devices, used by local inventory module
  • edid.ids is a database of Screen manufacturer, used by local inventory module
  • sysobject.ids is a database of SNMP devices, used by network discovery and network inventory modules
  • For Linux servers (when SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10), an additional check is done by

Those files can easily be customized if needed, as their format is self-documented. However, local modifications will get lost on upgrade.

SNMP device database

The sysobject.ids file is a database of known SNMP devices, indexed by the discriminant part of their SysObjectID value:

+           +       +               +
|           |       |               |
|           |       |               +-> device model
|           |       |
|           |       +-----------------> device type
|           |
|           +-------------------------> device manufacturer
+-------------------------------------> SysObjectID model-specific suffix

The SysObjectID suffix is the last part of the full SysObjectID value, ie:

+            +
|            |
|            +-----> model-specific suffix
+------------------> shared prefix

The SysObjectID value for any SNMP device can be retrieved by any SNMP client, using its OID (., or with either fusioninventory-netinventory or fusioninventory-netdiscovery command-line tools, with --debug option.

Where update the database?

This database is managed in one of our repositories on Github.

You can access it here and the instructions are on home page of the repository to contribute.
