- - title: Enable the samba collector
- description: |
- The `samba` collector is disabled by default. To enable it, use `edit-config` from the Netdata [config directory](https://github.com/netdata/netdata/blob/master/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](https://github.com/netdata/netdata/blob/master/docs/configure/start-stop-restart.md) for your system.
- - title: Permissions and programs
- description: |
- To run the collector you need:
-
- - `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
- ```

- There are 2 sections:
-
- * Global variables
- * One or more JOBS that can define multiple different instances to monitor.
-
- The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
-
- Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
-
- Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
