# -*- coding: utf-8 -*-
# Description: samba netdata python.d module
# Author: Christopher Cox <chris_cox@endlessnow.com>
#
# The netdata user needs to be able to be able to sudo the smbstatus program
# without password:
# netdata ALL=(ALL) NOPASSWD: /usr/bin/smbstatus -P
#
# This makes calls to smbstatus -P
#
# This just looks at a couple of values out of syscall, and some from smb2.
#
# The Lesser Ops chart is merely a display of current counter values. They
# didn't seem to change much to me. However, if you notice something changing
# a lot there, bring one or more out into its own chart and make it incremental
# (like find and notify... good examples).
