Built-In Metrics

Default deltastream query metrics provided by Prometheus integration

Queries in DeltaStream are long-lived and continuous. While DeltaStream provides its own tools to notify and alert you if your queries are misbehaving, you may want also to monitor queries from their own observability stacks. This document lists the built-in metrics that DeltaStream exposes so you can monitor your queries.
