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"
