Plugin: python.d.plugin Module: nsd


This collector monitors NSD statistics like queries, zones, protocols, query types and more.

It uses the nsd-control stats_noreset command to gather metrics.

This collector is supported on all platforms.

This collector only supports collecting metrics from a single instance of this integration.

Default Behavior


If permissions are satisfied, the collector will be able to run nsd-control stats_noreset, thus collecting metrics.


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.



NSD version

The version of nsd must be 4.0+.

Provide Netdata the permissions to run the command

Netdata must have permissions to run the nsd-control stats_noreset command.

You can:

  • Add “netdata” user to “nsd” group:

    usermod -aG nsd netdata
  • Add Netdata to sudoers

    1. Edit the sudoers file:
    visudo -f /etc/sudoers.d/netdata
    1. Add the entry:
    Defaults:netdata   !requiretty
    netdata ALL=(ALL)  NOPASSWD: /usr/sbin/nsd-control stats_noreset

    Note that you will need to set the command option to sudo /usr/sbin/nsd-control stats_noreset if you use this method.



The configuration file name for this integration is python.d/nsd.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 python.d/nsd.conf


This particular collector does not need further configuration to work if permissions are satisfied, but you can always customize it’s data collection behavior.

There are 2 sections:

  • Global variables
  • One or more JOBS that can define multiple different instances to monitor.

The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.

Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.

Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.

Name Description Default Required
update_every Sets the default data collection frequency. 30 False
priority Controls the order of charts at the netdata dashboard. 60000 False
autodetection_retry Sets the job re-check interval in seconds. 0 False
penalty Indicates whether to apply penalty to update_every in case of failures. yes False
name Job name. This value will overwrite the job_name value. JOBS with the same name are mutually exclusive. Only one of them will be allowed running at any time. This allows autodetection to try several alternatives and pick the one that works. False
command The command to run nsd-control stats_noreset False



A basic configuration example.

  name: 'nsd_local'
  command: 'nsd-control stats_noreset'


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 Name Server Daemon instance

These metrics refer to the entire monitored application.

This scope has no labels.


Metric Dimensions Unit
nsd.queries queries queries/s
nsd.zones master, slave zones
nsd.protocols udp, udp6, tcp, tcp6 queries/s
nsd.type A, NS, CNAME, SOA, PTR, HINFO, MX, NAPTR, TXT, AAAA, SRV, ANY queries/s
nsd.transfer NOTIFY, AXFR queries/s


There are no alerts configured by default for this integration.


Debug Mode

To troubleshoot issues with the nsd collector, run the python.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 python.d.plugin to debug the collector:

    ./python.d.plugin nsd debug trace
