What, and delay alerts by a possible 5 minutes?

I know many if our users would hunt you down and stab you in the face for making such a suggestion.

And his do you know that the upstream device which was up at the start of the poller run is still up at the end?

Messing with poller order is a bad idea.

Do the alerts get generated as each device polls? Just run the alerter when all pollers complete and take the parent device into account?

This is fiddly due to the way our poller runs as separated processes. You'd not be able to reliably suppress alerts this way, without also delaying them by up to 5 minutes.

I've asked about this before but how hard would it be for you guys to implement alert dependencies?

The easiest way I can think of doing it would be to simply let us set a "parent" device for anything, and if that device is offline don't send any alerts for downstream devices.

For example we have a testlab that has no UPS/Generator power that we monitor about 200 devices, when the building loses power we get those 200 alarms about devices being offline, when in reality there is a single 6500 as the gateway, and if that switch is offline, i know the rest will be.

We don't want to disable the offline alarms because we do want to know when individual devices drop out.

Thanks!
