TitleAvoid multiple notifications for a single problem on a single host

you have e. g. a machine with some oracle instances per instance there are multiple checks now if one instance goes down, you get multiple notifications (one per check) this is normally unwanted in classical Nagios setups service dependencies are used to avoid these but service dependencies have conceptual weaknesses a notification may or may not be sent, depending on the timing of the both checks as an alternative solution Mathias suggests: Throw counter wrap exceptions in case a dependent service fails dependent services should get stale in this case but this means a check needs to know on which other services it depends for the named oracle checks this should work fine so let's try it this way for other szenarios we might find a similar way
