+# netdata python.d.plugin configuration for nsd
+#
+# This file is in YaML format. Generally the format is:
+#
+# name: value
+#
+# There are 2 sections:
+# - global variables
+# - one or more JOBS
+#
+# JOBS allow you to collect values from multiple sources.
+# Each source will have its own set of charts.
+#
+# JOB parameters have to be indented (using spaces only, example below).
+
+# ----------------------------------------------------------------------
+# Global Variables
+# These variables set the defaults for all JOBs, however each JOB
+# may define its own, overriding the defaults.
+
+# update_every sets the default data collection frequency.
+# If unset, the python.d.plugin default is used.
+# nsd-control is slow, so once every 30 seconds
+# update_every: 30
+
+# priority controls the order of charts at the netdata dashboard.
+# Lower numbers move the charts towards the top of the page.
+# If unset, the default for python.d.plugin is used.
+# priority: 60000
+
+# retries sets the number of retries to be made in case of failures.
+# If unset, the default for python.d.plugin is used.
+# Attempts to restore the service are made once every update_every
+# and only if the module has collected values in the past.
+# retries: 5
+
+# ----------------------------------------------------------------------
+# JOBS (data collection sources)
+#
+# The default JOBS share the same *name*. 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.
+#
+# Any number of jobs is supported.
+#
+# All python.d.plugin JOBS (for all its modules) support a set of
+# predefined parameters. These are:
+#
+# job_name:
+# name: myname # the JOB's name as it will appear at the
+# # dashboard (by default is the job_name)
+# # JOBs sharing a name are mutually exclusive
+# update_every: 1 # the JOB's data collection frequency
+# priority: 60000 # the JOB's order on the dashboard
+# retries: 5 # the JOB's number of restoration attempts
+#
+# Additionally to the above, nsd also supports the following:
+#
+# command: 'nsd-control stats_noreset' # the command to run
+#
+
+# ----------------------------------------------------------------------
+# IMPORTANT Information
+#
+# Netdata must have permissions to run `nsd-control stats_noreset` command
+#
+# - Example-1 (use "sudo")
+# 1. sudoers (e.g. visudo -f /etc/sudoers.d/netdata)
+# Defaults:netdata !requiretty
+# netdata ALL=(ALL) NOPASSWD: /usr/sbin/nsd-control stats_noreset
+# 2. etc/netdata/python.d/nsd.conf
+# local:
+# update_every: 30
+# command: 'sudo /usr/sbin/nsd-control stats_noreset'
+#
+# - Example-2 (add "netdata" user to "nsd" group)
+# usermod -aG nsd netdata
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+
+local:
+ update_every: 30
+ command: 'nsd-control stats_noreset'
