Which looks for other Alert Action Rules and actual Alert Management rule never works. Release or EnvironmentFrom London ReleaseCauseBefore the London release ,alert action rules had the next logic: If there are several rules for create incident , only one with highest priority will be selected.Same is true for KB and acknowledge . But, if same alerts have different rules for incident, KB and acknowledge the algorithm wouldn’t stop only on the incident rule , it will try to check if there are matching rules for kb or acknowledge. That is why after migration the flag is set to “search for additional rules” since the logic of incident, KB, acknowledge can be spread between different rules. ResolutionIf there is no additional rules(Creating KB, Incident and other) in Alert Action Rule, up on migrating to Alert Management, set Multiple alert rules to "Stop Searching for additional rules".
