# PowerDNS Input Plugin
|
||||
|
||||
The powerdns plugin gathers metrics about PowerDNS using unix socket.
|
||||
|
||||
## 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][CONFIGURATION.md] 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.
|
||||
|
||||
