# Samba monitoring with Netdata
-Monitors the performance metrics of Samba file sharing.
+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`
-- `netdata` user needs to be able to sudo the `smbstatus` program without password
+- `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`
-It produces the following charts:
+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.
-1. **Syscall R/Ws** in kilobytes/s
+- Add to your `/etc/sudoers` file:
- - sendfile
- - recvfile
+`which smbstatus` shows the full path to the binary.
-2. **Smb2 R/Ws** in kilobytes/s
+```bash
+netdata ALL=(root) NOPASSWD: /path/to/smbstatus

- - writein
- - readin
- - writeout
+- Reset Netdata's systemd
+ unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux
+ distributions with systemd)
-3. **Smb2 Create/Close** in operations/s
+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`.
- - create
- - close
-4. **Smb2 Info** in operations/s
+As the `root` user, do the following:
- - getinfo
- - setinfo
+```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

+
+## 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
```
-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`.
+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
