# 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.
