The powerdns plugin gathers metrics about PowerDNS using unix socket.
Global configuration options
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 for more details.
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 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
Additionally, telegraf may need additional permissions. Look at the
socket-mode
PowerDNS option to set permissions on the socket.
