# TrueNAS vs FreeNAS:
#   TrueNAS is commercially-supported, while FreeNAS is community-supported.
#   FreeNAS is an open-source network attached storage platform.
#   TrueNAS is a set of open-source NAS operating systems developed by iXsystems.

# TODO: We can possibly support later FreeNAS devices by moving FREENAS-MIB metrics to a separate abstract profile,
#       that can be extended in by ixsystems-truenas.yaml but also a new FreeNAS profile (with sysobjectid 1.3.6.1.4.1.50536.3.1 FreeNAS).

extends:
  - _system-base.yaml
  - _std-host-resources-mib-feat-base.yaml
  - _std-if-mib.yaml
  - _std-ucd-mib.yaml
