Hi,

In Vitrage[3] project, we would like to be notified on every alarm that is triggered, and respond immediately (e.g. by generating RCA insights, or by triggering new alarms on other resources). We are now in the process of designing our integration with AODH.

If I understood you correctly, you want to remove the notifications to the bus, but keep the alarm_actions in the alarm definition? 
I'd be happy to get some more details about the difference between these two approaches, and why do you think the notifications should be removed.

Thanks,
Ifat.
