Dear all,
I have an Incident which has been previously created from an Alert through the following Incident rule :

Then as a test I have a created manually a dummy Alert of P2 priority only with a different Alias than initial Alert which create the incident.
By doing so the created alert below, has been associated to the current incident BUT it has nothing to do with it as it is an other one, I was expected that a different incident would be created.

Why opsgenie did not create new Incident ?
What is the rule that Opsgenie apply in order to know if it should create a new incident or associate the Alert to existing one ?
Thanks for clarification
regards
