What I propose is : * A,B,C of: foo,foo2,foo3 The A is for : "It's OK if at least A are OK/UP" The B is for "It's Warning if at least B are Warning or Critical/DOWN" The C is for "It's Critical is at least C are Critical/Down" And the classic "A of:" will just be "A,A,Aof:" for keeping the current behavior. Here are some examples for 5 services A->E, and states (O = OK, W = waring, C = critical). * W O O O O * 4 of: -> Ok (we got 4 OK, and not 4 warn or crit, so it's OK) * 5,1,1 -> Warning (at least one warning, and no crit -> warning) * 5,2,1 -> OK (we want warning only if we got 2 bad states, so not here) * W C O O O * 4 of: -> Crtitical (not 4 ok, so we take the worse state, the critical) * 4,1,1 -> Critical (2 states raise the waring, but on raise critical, so worse state is critical) * W C C O O * 2 of: OK * 4,1,1 -> Critical (same as before) * 4,1,3 -> warning (the warning rule is raised, but the critical is not) And so there are the most used cases (for M elements): * ON/OFF indicator, for printing usage : M of: * Warning as soon as problem, and critical only if all are critical : M,1,M * "Direct and Real state" (if there is a warning, it's waring, if there is a critical, it's critical) : M,1,1 I think it will be not so hard to code (the hardest part will be the regexp for me....:p ), it keep the current simple behavior ( | and & are still pure boolean, the 2of: is kept). What do you think of it? Jean
