Unlike the detection pipeline, root cause analysis (RCA) algorithms have a limited set of aggregation functions available. If the metric used for RCA is onboarded in ThirdEye, a default aggregation function is available. If the metric is a derived metric or is not onboarded in ThirdEye, the aggregation function should be set in the alert configuration aggregationFunction field.
