[//]: # (werk v2) # chrony: change default warning level key | value ---------- | --- date | 2024-08-19T06:14:01+00:00 version | 2.4.0b1 class | fix edition | cre component | checks level | 1 compatible | no Chrony's default `minpoll` and `maxpoll` values are 64 seconds and 1024 seconds. In standard situations (good internet connection, low error etc) the interval between polls should stick near the max value (1024 seconds). (see `https://chrony-project.org/examples.html#_client_using_public_servers`) Beacuse of that, the default WARN alert is now set to 1025 seconds.
