# 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.
