Hey Carsten,
Well, I'm a little behind with all this, but...

Yeah, the purist in me would like "Network Observation" but the words "observability" seems to have currency.
I changed the first words to be "The Network Observability process is"

Not sure, to be honest.
The definition of network monitoring says to distinguish it from resource or device monitoring.
Any suggestions for wording?

We are being very careful with "familiar usage" because, we find, everyone's familiar usage is different.
Anyway, a fault does not go away or stay. For that to happen it would need to be a state. A fault is an occurrence, that is, an event.

Ah, the fallacy fallacy :-)
We have "an Alarm signifies an undesirable State"
So, prima facie, an alarm requires corrective action.
But, in fact, it’s a bit tighter than that because the definition does not say that an alarm indicates that corrective action is needed, it says that an alarm indicates a state that requires corrective action.
Now, if we are to handle everything as "but it might not really be true" then our world (and definitions) break down!
In this case, a false alarm would be one of:
- here is an alarm reporting a state, but actually, the resource is not in that state
- here is an alarm reporting an undesirable state, but really, the state is not undesirable
- here is an alarm reporting an undesirable state that requires corrective action, but in truth, you don't need to correct it.
In all of those "false alarms" there is actually no alarm, just a bit of bogus information.

Yes, no reason to capitalise when we don't have a defined term.
Yes, better to stick to "network fault and problem management"

Thanks. Superfluous comma.

Correct. That is not the only use of colons.
But I will change it to "where the following relationships apply."

I hope it isn't a requirement that we surprise you :-)
In conjunction with the previous note, this is observing that the state that we care about from an operational point of view is resolved, but the problem persists ("we don't know why that happened") and attention may be required.

Yeah, I have been told. I will change to "while" which is more sympathetic to the American ear.

I'll add a note.

US/UK issue.
Leaving it to the RFC Editor as I react badly to the Germanification of my language via the US.
