Trigger of triggers

[acarr]

Hi,

Is it possible to write a trigger that reads the values of other triggers on the same host? For example, one trigger to alarm if any of various other triggers are active?

I am looking at mapping a cooling system, I have three discrete services within each host, fault alarms, flow (cooling) temperatures and return (heated) temperatures. Each service has various trigger, and each service I want to represent on a map and only warn when its specific triggers are active.

I can't use host checks on these as when any trigger alarms, each icon will alert for it, I can't use trigger checks on these as there are multiple triggers per service. What I want is one trigger that aggregates the various triggers per service so that I can use trigger checks in that map?

Is this feasible?

Many Thanks.

Having implemented hysteresis inside my checks and worked with the trigger macros, I imagine that if something like this were to work, it would be done with a macro similar to the typical {host:key.func(param)} but merging in the {TRIGGER.VALUE} somewhere almost like a {host:trigger.value}.

Is this something in the codebase that I've missed or something of a wishlist item?

My suggestion would be trigger dependency

I can see where you're coming from with this but what I'd really like with this is to still be able to see specifically what the underlying problem is, not just that there is a problem of sorts. I've got around this by choosing to not show all of that information on my map, instead I'm reporting on triggers with one host icon and using two simple image icons to report only the key metrics for these.

Another Use Case

I'm coming back to this idea of triggers based on trigger with a further step I'm looking at Zabbix for, a double knock methodology.

Much in the same way that a fire alarm system works, a smoke sensor could trigger and simply be a faulty sensor, following on a radiation sensor could also trigger and because of the two warning readings, the building alarm goes off.

I want to be able to take the status of triggers in other triggers I write and use them to refine the severity of problems; for instance, if host 'a' triggers a warning and host 'b' triggers a related warning, that either of/or both hosts 'a' and 'b' trigger a critical problem.

I also think this would be a good feature.

This would also be helpful to monitor IT Services / SLAs.

"Immediate" IT Services / SLAs

Yes, the IT Services / SLAs are the answer, but an immediate responde is neccesary (as soon as a trigger is activated).
