+
+## Overview
+
+This collector monitors the performance metrics of Samba file sharing.
+
+It is using the `smbstatus` command-line tool.
+
+Executed commands:
+
+- `sudo -n smbstatus -P`
+
+
+This collector is supported on all platforms.
+
+This collector only supports collecting metrics from a single instance of this integration.
+
+`smbstatus` is used, 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.
+
+
+### Default Behavior
+
+#### Auto-Detection
+
+After all the permissions are satisfied, the `smbstatus -P` binary is executed.
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per Samba instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| syscall.rw | sendfile, recvfile | KiB/s |
+| smb2.rw | readout, writein, readin, writeout | KiB/s |
+| smb2.create_close | create, close | operations/s |
+| smb2.get_set_info | getinfo, setinfo | operations/s |
+| smb2.find | find | operations/s |
+| smb2.notify | notify | operations/s |
+| smb2.sm_counters | tcon, negprot, tdis, cancel, logoff, flush, lock, keepalive, break, sessetup | count |
+
+
+
+## Alerts
+
+There are no alerts configured by default for this integration.
+
+
+## Setup
+
+### Prerequisites
+
+#### Enable the samba collector
+
+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.
+
+
+#### Permissions and programs
+
+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
+ ```
+
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `python.d/samba.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config python.d/samba.conf
+```
+#### Options
+
+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.
+
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Sets the default data collection frequency. | 5 | no |
+| priority | Controls the order of charts at the netdata dashboard. | 60000 | no |
+| autodetection_retry | Sets the job re-check interval in seconds. | 0 | no |
+| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | no |
+
+</details>
+
+#### Examples
+
+##### Basic
+
+A basic example configuration.
+
+<details><summary>Config</summary>
+
+```yaml
+my_job_name:
+ name: my_name
+ update_every: 1
+
+```
+</details>
+
+
+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `samba` collector, run the `python.d.plugin` with the debug option enabled. The output
+should give you clues as to why the collector isn't working.
+
+- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
+ your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
+
+ ```bash
+ cd /usr/libexec/netdata/plugins.d/
+ ```
+
+- Switch to the `netdata` user.
+
+ ```bash
+ sudo -u netdata -s
+ ```
+
+- Run the `python.d.plugin` to debug the collector:
+
+ ```bash
+ ./python.d.plugin samba debug trace
+ ```
+
+
