Amazon QLDB

Dynatrace ingests metrics for multiple preselected namespaces, including Amazon QLDB. You can view graphs per service instance, with a set of dimensions, and create custom graphs that you can pin to your dashboards.

How Dynatrace displays your service metrics

Dashboard qldb Custom device page qldb-overview

Note: In Dynatrace, the custom device group is the whole Amazon QLDB service. Each custom device is a ledger. For each custom device you'll see the metrics IsImpaired for Streams and CommandLatency for Command types aggregated on the overview page, and in Further details they are split by the different Streams and Command types.
