• Affects Version/s: 1.16.0
• Fix Version/s: 1.17.0, 1.16.1
• Component/s: Runtime / Metrics
• Labels: pull-request-available
• Release Note: The Datadog reporter now adds a "flink." prefix to metric identifiers if "useLogicalIdentifier" is enabled. This is required for these metrics to be recognized as Flink metrics, not custom ones.

Description

Custom metrics in the DD context are meant for metrics not exported by the standard integrations (which includes our reporter), but seemingly enabling the useLogicalIdentifier flag breaks whatever detection mechanism they have for the reporter.
This results in additional costs to users.
