+title: "Chrony monitoring with Netdata"

+
+# Chrony monitoring with Netdata
+
+Monitors the precision and statistics of a local chronyd server, and produces:
+
+- frequency
+- last offset
+- RMS offset
+- residual freq
+- root delay
+- root dispersion
+- skew
+- system time
+
+## Requirements
+
+Verify that user Netdata can execute `chronyc tracking`. If necessary, update `/etc/chrony.conf`, `cmdallow`.
+
+## Enable the collector
+
+The `chrony` collector is disabled by default. To enable it, use `edit-config` from the Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `python.d.conf` file.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d.conf
+```
+
+Change the value of the `chrony` setting to `yes`. Save the file and restart the Netdata Agent with `sudo systemctl
+restart netdata`, or the appropriate method for your system, to finish enabling the `chrony` collector.
+
+## Configuration
+
+Edit the `python.d/chrony.conf` configuration file using `edit-config` from the Netdata [config
+directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
+
+```bash
+cd /etc/netdata # Replace this path with your Netdata config directory, if different
+sudo ./edit-config python.d/chrony.conf
+```
+
+Sample:
+
+```yaml
+# data collection frequency:
+update_every: 1
+
+# chrony query command:
+local:
+ command: 'chronyc -n tracking'
+```
+
+Save the file and restart the Netdata Agent with `sudo systemctl restart netdata`, or the appropriate method for your
+system, to finish configuring the `chrony` collector.

+# netdata python.d.plugin configuration for chrony
+#
+# 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.
+update_every: 5
+
+# 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
+
+# penalty indicates whether to apply penalty to update_every in case of failures.
+# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
+# penalty: yes
+
+# autodetection_retry sets the job re-check interval in seconds.
+# The job is not deleted if check fails.
+# Attempts to start the job are made once every autodetection_retry.
+# This feature is disabled by default.
+# autodetection_retry: 0
+
+# ----------------------------------------------------------------------
+# 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
+# penalty: yes # the JOB's penalty
+# autodetection_retry: 0 # the JOB's re-check interval in seconds
+#
+# Additionally to the above, chrony also supports the following:
+#
+# command: 'chrony tracking' # the command to run
+#
+
+# ----------------------------------------------------------------------
+# REQUIRED chrony CONFIGURATION
+#
+# netdata will query chrony as user netdata.
+# verify that user netdata is allowed to call 'chronyc tracking'
+# Check cmdallow in chrony.conf
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
