Fleet metrics - AWS IoT Core

Fleet metrics

Fleet metrics is a feature of fleet indexing, a managed service that allows you to index, search, and aggregate your devices' data in AWS IoT. You can use fleet metrics, to monitor your fleet devices' aggregate state in CloudWatch over time, including reviewing your fleet devices' disconnection rate or average battery level changes of a specified period.

Using fleet metrics, you can build aggregation queries whose results are continually emitted to CloudWatch as metrics for analyzing trends and creating alarms. For your monitoring tasks, you can specify the aggregation queries of different aggregation types (Statistics, Cardinality, and Percentile). You can save all of your aggregation queries to create fleet metrics for reuse in the future.
