How to create trigger on string change that gets back to OK when string changes back

[rmc]

I want to have a trigger on our firewalls that fires when it changes from Active to Passive or vice versa.
I have one now but that only compares the last value with the current one.
Trigger:
(last(/Template Palo Alto Firewall/panSysHAState,#1)<>last(/Template Palo Alto Firewall/panSysHAState,#2))=1

So if there is a failover from Active to Passive, it fires because the value is different. But since this value is read every minute, after a minute the trigger is OK because then the last value is the same as he current (still Passive).

What I want is that the trigger stays active until the value gets back to Active.

Any ideas?

So you want trigger to fire, when state turns to "Passive" and stays there until it is Active again?
I don't know the actual values you collect but if we assume that Active is 0 and passive is 1, then you trigger should be "last(/host/item)=1". Until this value is still 1, that trigger is active, when it turns to 0, trigger resolves... and then you can have second trigger for opposite situation... You cannot have a trigger that is "true" in both cases and fires, when that case changes..

Exactly what I thought.
I was just hoping I was missing something...
