Chrony: NTP Time Synchronization

Distribution	Official part of Checkmk
Lizenz	GPLv2
Unterstützte Agenten	Linux

This check uses the output of chronyc tracking in order to check the time synchronization when using chrony. The check is very similar to ntp, which monitors the ntpd, but it does not support jitter.

You can set levels for the maximum stratum and for the time offset in milliseconds. The configuration is compatible with ntp.

The default WARN alert is set to 1025 seconds (default chrony's maxpoll values is 1024 seconds, see https://chrony-project.org/examples.html#_client_using_public_servers) and thus differs from the default WARN alert of the NTP check.

When chrony is not found running, the check goes to CRIT.

Discovery

One service is created if chrony is running.
