# samba

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
```
