getTopPrcDetails

A Graze API GET request that returns the top most likely causal alerts, based on their Probable Root Cause value, for a specified Situation.

You can select the maximum number of causal alerts to return using a limit value. If not specified, the endpoint only returns the alert with the highest root cause probability.

The entries returned are ordered with the highest root cause probability first, for the specified Situation, irrespective of whether they have been labeled causal or are unlabeled. Alerts marked as symptoms are excluded from the return.
