awa-metrics

OpenTelemetry metric definitions shared across the Awa job queue crates.

awa-metrics is an implementation detail of Awa. The metric names and attribute sets are public (so dashboards / alerts can build against them), but the Rust API is not intended for direct use outside the Awa workspace — awa-worker re-exports AwaMetrics from this crate, and that's the supported entry point.

The crate is published to crates.io because awa-worker depends on the type directly; cargo publish strips path dependencies, so consumers of awa-worker need to resolve awa-metrics from the registry.

Metric naming

All metrics use the awa meter name and follow OpenTelemetry naming and unit guidance: dot-separated namespaces (awa.job.*, awa.dispatch.*, …), singular nouns, and UCUM units declared via with_unit where a unit applies. The metric names and attributes are Awa-specific rather than standardized semantic-convention metrics. Names are exported as constants from awa_metrics::names for tests asserting against an OTLP exporter.
