Actually, when we want to use pairwise correlation in NNMi, incident attribute must be strictly equals. It would be great if we can have more operator available in pairwise correlation, for example : regular expression or substring operator.
I have a use case where i want to use pairwise correlation with F5 Bigip traps incidents. Unfortunately those traps have a snmp variable that contains the name of the VS with "has become available" or "has become unavailable" appended, so it prevents the use of pairwise correlation.
I think it would be a great enhancement for NNMi to able to correlate those traps.
