  You must specify a valid hostname or os.

  -v, --variant     The variant of the OS to use, usually the device model
  -m, --modules     The discovery/poller module(s) to collect data for, comma delimited
  -f, --file        File to save the database entries to.  Default is in tests/data/
  -d, --debug       Enable debug output
  -n, --prefer-new  Prefer new snmprec data over existing data
      --no-save     Don't save database entries, print them out instead
      --snmpsim     Just run snmpsimd.py for manual testing.
