capability to auto assign P1 priority to a proactive incident when 50%

[Snowl13052025]

capability to auto assign P1 priority to a proactive incident when 50% or more devices (Router) at a site location go down.

1. First router down at a site
   → Create P2 incident (standard BAU behavior).
2. While Router1 is already down (incident open), Router2 at the same site goes down
   → Check all routers for the site.
   → If more than 50% of routers at that site have active alerts, then:
   • Create a new P1 incident immediately (0 sec wait).
3. Generic rule
   → If >50% of site routers have active “Router Down” alerts at any time
   → Raise P1 with 0 sec wait.

could anyone please help to develop this in the event management 

Thanks in advance.
