in my environment i also use passive checks, some tests results submitted once a week or month.
with one of the latest centreon version (in mycase Centreon 25.10.14) passive checks also gets down if host check fails and stays in this state until next passive test result.
i’m using activated “Disable Service Checks When Host Down”
with older centreon versions the passive checks weren’t changed if a hosts get down and you use this option (only the active ones).
I’m not sure with what version this behavior changed, it think with 24.10 it worked like before
