# 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
```
