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

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

samba is disabled by default. Should be explicitly enabled in python.d.conf.
