Telltale provides Edgar with latency benchmarks that indicate if the individual trace’s latency is abnormal for this given service. Telltale’s anomaly analysis looks at historic behavior and can evaluate whether the latency experienced by this trace is anomalous. Is this an anomaly or are we dealing with a pattern?
