I'ld say that our discussion is perpendicular to the issue you raise -
or, in other words, that first_notification_delay is unlikely to
suddenly work the way you want afterwards.
You see, while everyone just calls it "passive checks", the terminology
in the web UI - "active checks disabled" - is more correct. (Yes, a
service *could* have active *and* passive check results going into it.
I've just never seen a working setup doing that, or a use case seriously
asking for it.) Using "passive checks" means that Nagios can forget
about scheduling commands for that service, ever; waiting for events and
reacting to them is all that's required.
Asking that Nagios now *should* schedule a notification being sent
first_notification_delay after receiving a non-OK passive result sort of
negates the entire concept.
What I'ld try in your place is to write the (last) trap into a cache
file, and then run an *active* check looking for the reported state *and
timestamp*, possibly differentiating WARNING/CRITICAL based on the latter=
.
(Note to others: Actively checking the UPS' *current* state directly
could yield false positives *if* the UPS / power keeps flapping and the
active checks just *happen* to see only the on-battery state for a
couple times in a row.)
