Get overall bucket results
- POST also GET /_ml/anomaly_detectors/{job_id}/results/overall_buckets
Retrievs overall bucket results that summarize the bucket results of multiple anomaly detection jobs.
The overall_score is calculated by combining the scores of all the
buckets within the overall bucket span. First, the maximum
anomaly_score per anomaly detection job in the overall bucket is
calculated. Then the top_n of those scores are averaged to result in
the overall_score. This means that you can fine-tune the
overall_score so that it is more or less sensitive to the number of
jobs that detect an anomaly at the same time. For example, if you set
top_n to 1, the overall_score is the maximum bucket score in the
overall bucket. Alternatively, if you set top_n to the number of jobs,
the overall_score is high only when all jobs detect anomalies in that
overall bucket. If you set the bucket_span parameter (to a value
greater than its default), the overall_score is the maximum
overall_score of the overall buckets that have a span equal to the
jobs' largest bucket span.
