+
+Performance metrics of Samba file sharing.
+
+**Requirements:**
+* `smbstatus` program
+* `sudo` program
+* `smbd` must be compiled with profiling enabled
+* `smbd` must be started either with the `-P 1` option or inside `smb.conf` using `smbd profiling level`
+* `netdata` user needs to be able to sudo the `smbstatus` program without password
+
+It produces the following charts:
+
+1. **Syscall R/Ws** in kilobytes/s
+ * sendfile
+ * recvfle
+
+2. **Smb2 R/Ws** in kilobytes/s
+ * readout
+ * writein
+ * readin
+ * writeout
+
+3. **Smb2 Create/Close** in operations/s
+ * create
+ * close
+
+4. **Smb2 Info** in operations/s
+ * getinfo
+ * setinfo
+
+5. **Smb2 Find** in operations/s
+ * find
+
+6. **Smb2 Notify** in operations/s
+ * notify
+
+7. **Smb2 Lesser Ops** as counters
+ * tcon
+ * negprot
+ * tdis
+ * cancel
+ * logoff
+ * flush
+ * lock
+ * keepalive
+ * break
+ * sessetup
+
+### prerequisite
+This module uses `smbstatus` which can only be executed by root.  It uses
+`sudo` and assumes that it is configured such that the `netdata` user can
+execute `smbstatus` as root without password.
+
+Add to `sudoers`:
+
+    netdata ALL=(root)       NOPASSWD: /path/to/smbstatus
+
+### configuration
+
+ **samba** is disabled by default. Should be explicitly enabled in `python.d.conf`.
+
+```yaml
+samba: yes
+```

+# There are 2 sections:

+#  - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB

+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+update_every: 5

+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.

+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 60

+# JOBS (data collection sources)

+# The default JOBS share the same *name*. JOBS with the same name

+# pick the one that works.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+#     name: myname            # the JOB's name as it will appear at the
+#                             # dashboard (by default is the job_name)
+#                             # JOBs sharing a name are mutually exclusive
+#     update_every: 1         # the JOB's data collection frequency
+#     priority: 60000         # the JOB's order on the dashboard
