Methods, root cause analysis (RCA) engines, and monitoring systems for controlling monitoring systems based on RCA are provided. An RCA engine of a hardware computer receives an alarm on an entity. The RCA engine fetches correlation domains based on the correlation domains each having been associated with the entity and in which the alarm is part of a policy applied to the correlation domains. The RCA engine determines if the alarm is for a root cause of failure for an entity in one of the correlation domains and responsive to the alarm being for the root cause of failure: transmits a message to monitoring systems, the message comprising instructions for the registered monitoring systems to stop monitoring symptom conditions associated with the root cause of failure, and transmits, through the network, an indication of a failure of the one of the entities that is the root cause of failure.
