+# 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).
