Aggregated metrics

The following screenshot shows the Aggregated metrics section, where it shows metrics for all the resources that it detected anomalies in (DynamoDB, Lambda, and API Gateway). Note that depending upon your traffic pattern, Lambda settings, baseline traffic, the list of metrics may vary. In the example below, the timeline shows that an anomaly for DynamoDB started first and was followed by API Gateway and Lambda. This helps us understand the cause and symptoms, and prioritize the right anomaly investigation.

The listing of metrics inside an Insight

Initially, you may see only two metrics listed, however, over time, it populates more metrics that showed anomalies. You can see the anomaly for DynamoDB started earlier than the anomalies for API Gateway and Lambda, thus indicating them as after effects. In addition to the information in the preceding screenshot, you may see Duration p90 and IntegrationLatency p90 (for Lambda and API Gateway respectively, due to increased backend latency) metrics also listed.
