The powerdns plugin gathers metrics about PowerDNS using unix socket.
Configuration
# 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 read access to the powerdns control socket.
On many systems this can be accomplished by adding the telegraf
user to the
pdns
group:
usermod telegraf -a -G pdns
