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"
## The version of the PowerDNS control protocol to use. You will have to
## change this based on your PowerDNS Recursor version, see below:
## Version 1: PowerDNS <4.5.0
## Version 2: PowerDNS 4.5.0 - 4.5.11
## Version 3: PowerDNS >=4.6.0
## By default this is set to 1.
# control_protocol_version = 1
By default, this plugin is compatible with PowerDNS Recursor versions older
than 4.5.0
. If you are using a newer version then you'll need to adjust the
control_protocol_version
configuration option based on your version. For
versions between 4.5.0
and 4.5.11
set it to 2
and for versions 4.6.0
and newer set it to 3
. If you don't, you will get an i/o timeout
or a
protocol wrong type for socket
error.
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 = 660
Then place the telegraf
user into the pdns
group:
usermod telegraf -a -G pdns
Since 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
