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.
