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, which is typically at /etc/netdata, to edit the python.d.conf file.

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, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/chrony.conf

Sample:

# 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.
