OpenTelemetry metric export for Relay metric marks.

## Structs

* [OpenTelemetryMetricConfig](/reference/api/rust-library-reference/nemo-relay/observability/otel_metrics/struct-opentelemetrymetricconfig): Configuration for an OTLP metric subscriber.
* [OpenTelemetryMetricSubscriber](/reference/api/rust-library-reference/nemo-relay/observability/otel_metrics/struct-opentelemetrymetricsubscriber): OpenTelemetry metric-backed Relay event subscriber.

## Enums

* [MetricTemporality](/reference/api/rust-library-reference/nemo-relay/observability/otel_metrics/enum-metrictemporality): Preferred aggregation temporality for OTLP metrics.

## Functions

* [resolve\_http\_metric\_endpoint](/reference/api/rust-library-reference/nemo-relay/observability/otel_metrics/fn-resolve-http-metric-endpoint): Resolve an OTLP/HTTP endpoint for the metrics signal.
