Filter on alerting only when the service is the root cause

[bernardifa]

Hi guys
is it possible to send an alert only if a service is the root cause of the problem and not if it's only impacted?

I've tried to create a custom event property on a entity name:
Custom: event property root_cause_entity_name not equals 'XXXXXXX'

Could this works?

In theory yes that should work. have you added it in and tested it?

Unfortunately not.
I had to look on last 30 days
I've found a problem that has been sent also by an alerting profile a configured this way: 

Custom: event property root_cause_entity_name not equals '<name>'
