# 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](/docs/configure/start-stop-restart.md) for your system, to finish configuring the `chrony` collector.
