# Samba monitoring with Netdata
Monitors the performance metrics of Samba file sharing using `smbstatus` command-line tool.
Executed commands:
- `sudo -n smbstatus -P`
## 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`
The 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 a
password.
- Add to your `/etc/sudoers` file:
`which smbstatus` shows the full path to the binary.
```bash
netdata ALL=(root) NOPASSWD: /path/to/smbstatus
```
- Reset Netdata's systemd
unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux
distributions with systemd)
The default CapabilityBoundingSet doesn't allow using `sudo`, and is quite strict in general. Resetting is not optimal, but a next-best solution given the inability to execute `smbstatus` using `sudo`.
As the `root` user, do the following:
```cmd
mkdir /etc/systemd/system/netdata.service.d
echo -e '[Service]\nCapabilityBoundingSet=~' | tee /etc/systemd/system/netdata.service.d/unset-capability-bounding-set.conf
systemctl daemon-reload
systemctl restart netdata.service
```

2. **Smb2 R/Ws** in kilobytes/s

- 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
## Enable the collector
The `samba` collector is disabled by default. To enable it, use `edit-config` from the
Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `python.d.conf`
file.
```bash
cd /etc/netdata # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d.conf
```
Change the value of the `samba` setting to `yes`. Save the file and restart the Netdata Agent
with `sudo systemctl restart netdata`, or the appropriate method for your system.
## Configuration
Edit the `python.d/samba.conf` configuration file using `edit-config` from the
Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
```bash
cd /etc/netdata # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/samba.conf
```
