Hi @whity
I’m not sure if I understand your question correctly, so I’ll take a wild guess: Do you mean how you can see whether a rule does or doesn’t apply for a particular service? Perhaps this part of the documentation, i.e. The analysis mode with ‘traffic lights’ is of interest for you. It may be, that some “other” rule overrides the rule(s) that you perceive as not working.
BTW, how’s it going with your mk_oracle on AIX issue?
