Previously, services configured to be ignored by the "Disabled services" ruleset were written into the autochecks file. Moreover, they were never removed from autochecks, even when they vanished from the data source content.
This led to ever-growing autochecks files — especially on hosts with volatile services, such as those in Kubernetes or Docker environments, but not limited to these.
With this Werk, services matched by "Disabled services" are no longer written into autochecks. Previously accumulated entries for such services will now appear as vanished during service discovery.
To clean up existing autochecks, run a re-discovery on the affected hosts to remove these services.
