# PowerDNS Recursor Input Plugin
|
||||
|
||||
The powerdns recursor plugin gathers metrics about PowerDNS Recursor using unix socket.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```
|
||||
# Read metrics from one or many PowerDNS recursors
|
||||
[[inputs.powerdns_recursor]]
|
||||
## An array of sockets to gather stats about.
|
||||
## Specify a path to unix socket.
|
||||
##
|
||||
## If no servers are specified, then '/var/run/pdns_recursor.controlsocket' is used as the path.
|
||||
unix_sockets = ["/var/run/pdns_recursor.controlsocket"]
|
||||
|
||||
## Socket for Receive
|
||||
# socket_dir = "/var/run/"
|
||||
## Socket permissions
|
||||
# socket_mode = "0666"
|
||||
```
