{
  "monitoringStats": [
    {
      object (ModelMonitoringStatsAnomalies)
    }
  ],
  "nextPageToken": string
}

StatsAnomaliesObjective

Stats requested for specific objective.

Fields
type enum (ModelDeploymentMonitoringObjectiveType)
topFeatureCount integer

If set, all attribution scores between SearchModelDeploymentMonitoringStatsAnomaliesRequest.start_time and SearchModelDeploymentMonitoringStatsAnomaliesRequest.end_time are fetched, and page token doesn't take effect in this case. Only used to retrieve attribution score for the top Features which has the highest attribution score in the latest monitoring run.
