adk_observability_metrics (erlang_adk v0.7.0)

View Source

Bounded low-cardinality metric aggregation for Erlang ADK.

This is an SDK-neutral registry. It keeps a small in-memory snapshot that an OpenTelemetry/Prometheus adapter may scrape. Series beyond the configured per-instrument cap are merged into one explicit overflow series instead of allocating labels without bound.
