The powerdns_recursor plugin gathers metrics about PowerDNS Recursor using
the unix controlsocket.
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.
# Read metrics from one or many PowerDNS Recursor servers
[[inputs.powerdns_recursor]]
## Path to the Recursor control socket.
unix_sockets = ["/var/run/pdns_recursor.controlsocket"]
## Directory to create receive socket. This default is likely not writable,
## please reference the full plugin documentation for a recommended setup.
# socket_dir = "/var/run/"
## Socket permissions for the receive socket.
# socket_mode = "0666"Telegraf will need read/write access to the control socket and to the
socket_dir. PowerDNS will need to be able to write to the socket_dir.
The setup described below was tested on a Debian Stretch system and may need adapted for other systems.
First change permissions on the controlsocket in the PowerDNS recursor
configuration, usually in /etc/powerdns/recursor.conf:
socket-mode = 660Then place the telegraf user into the pdns group:
usermod telegraf -a -G pdnsSince telegraf cannot write to to the default /var/run socket directory,
create a subdirectory and adjust permissions for this directory so that both
users can access it.
mkdir /var/run/pdns
chown root:pdns /var/run/pdns
chmod 770 /var/run/pdns- powerdns_recursor
