Hello,

I've got a question that's been bugging me. I couldn't find it by searching over the community.

Let's say we've got a service consisting of 2 parameters from 2 different elements. Let's call those parameters A and B.

Suppose I want to make the service in a major alarm whenever one of those parameters is outside of its normal operating range. (by itself can be done using simple alarm configuration)

However things complicate when I would want the service to go critical when no parameter is in its "normal" state (for example A critical, B warning; A and B on warning)

I know about the existence of "Enchanced services", but I have never seen a protocol for a service. This means that I don't even have a clue on where to begin writing such a protocol.

Any tips or tricks on doing such a simple task with a service?
