+# The netdata user needs to be able to be able to sudo the smbstatus program

+# 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).
