DNS query

Plugin: go.d.plugin Module: dns_query


This module monitors DNS query round-trip time (RTT).

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior


This integration doesn’t support auto-detection.


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



No action required.



The configuration file name for this integration is go.d/dns_query.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/dns_query.conf


The following options can be defined globally: update_every, autodetection_retry.

Name Description Default Required
update_every Data collection frequency. 1 False
autodetection_retry Recheck interval in seconds. Zero means no recheck will be scheduled. 0 False
domains Domain or subdomains to query. The collector will choose a random domain from the list on every iteration. True
servers Servers to query. True
port DNS server port. 53 False
network Network protocol name. Available options: udp, tcp, tcp-tls. udp False
record_types Query record type. Available options: A, AAAA, CNAME, MX, NS, PTR, TXT, SOA, SPF, TXT, SRV. A False
timeout Query read timeout. 2 False



An example configuration.

  - name: job1
      - A
      - AAAA
      - google.com
      - github.com
      - reddit.com


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per server

These metrics refer to the DNS server.


Label Description
server DNS server address.
network Network protocol name (tcp, udp, tcp-tls).
record_type DNS record type (e.g. A, AAAA, CNAME).


Metric Dimensions Unit
dns_query.query_status success, network_error, dns_error status
dns_query.query_time query_time seconds


The following alerts are available:

Alert name On metric Description
dns_query_query_status dns_query.query_status DNS request type ${label:record_type} to server ${label:server} is unsuccessful


Debug Mode

To troubleshoot issues with the dns_query 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, open netdata.conf and look for the plugins 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 dns_query
