# PowerDNS Input Plugin

This plugin gathers metrics from [PowerDNS](https://www.powerdns.com/) servers using unix
sockets.

> [!NOTE]
> This plugin will need access to the powerdns control socket.

**Introduced in:** Telegraf v0.10.2
**Tags:** server
**OS support:** all

[powerdns]: https://www.powerdns.com/

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# Read metrics from one or many PowerDNS servers
[[inputs.powerdns]]
  # An array of sockets to gather stats about.
  # Specify a path to unix socket.
  #
  # If no servers are specified, then '/var/run/pdns.controlsocket' is used as the path.
  unix_sockets = ["/var/run/pdns.controlsocket"]
```

### Permissions

Telegraf will need access to the powerdns control socket. On many systems this
can be accomplished by adding the `telegraf` user to the `pdns` group:

```sh
usermod telegraf -a -G pdns
```

Additionally, telegraf may need additional permissions. Look at the
`socket-mode` PowerDNS option to set permissions on the socket.
