PowerDNS Recursor collector
PowerDNS Recursor
is a high-performance DNS recursor with built-in scripting
capabilities.
This module monitors one or more PowerDNS Recursor
instances, depending on your configuration.
It collects metrics from the internal webserver.
Used endpoints:
Requirements
For collecting metrics via HTTP, we need:
Metrics
All metrics have "powerdns_recursor." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
questions_in | global | total, tcp, ipv6 | questions/s |
questions_out | global | udp, tcp, ipv6, throttled | questions/s |
answer_time | global | 0-1ms, 1-10ms, 10-100ms, 100-1000ms, slow | queries/s |
timeouts | global | total, ipv4, ipv6 | timeouts/s |
drops | global | over-capacity-drops, query-pipe-full-drops, too-old-drops, truncated-drops, empty-queries | drops/s |
cache_size | global | cache, packet-cache, negative-cache | entries |
Configuration
Edit the go.d/powerdns_recursor.conf
configuration file using edit-config
from the
Netdata config directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/powerdns_recursor.conf
To add a new endpoint to collect metrics from, or change the URL that Netdata looks for, add or configure the name
and
url
values. Endpoints can be both local or remote as long as they expose their metrics on the provided URL.
Here is an example with two endpoints:
jobs:
- name: local
url: http://127.0.0.1:8081
- name: remote
url: http://203.0.113.0:8081
For all available options, see the PowerDNS Recursor collector's configuration file.
Troubleshooting
To troubleshoot issues with the powerdns_recursor
collector, run the go.d.plugin
with the debug option enabled. The
output should give you clues as to why the collector isn't working.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m powerdns_recursor
