MetricKey

@Serializable

data class MetricKey(val name: String, val kind: MetricKind, val attributes: Map<String, String> = emptyMap())

The identity of a single metric time series.

Metrics with the same name and kind but different attributes are distinct series — this is the standard OpenTelemetry label-set model. MetricKey is the map key inside WarpMetricExporter; use the same key on every increment/set/add to accumulate into the same series.

Parameters

name

Human-readable metric name. Must not be blank.

kind

The measurement kind: MetricKind.SUM, MetricKind.GAUGE, or MetricKind.CARDINALITY.

attributes

Key/value label set that differentiates series within the same metric name (e.g. {"path" to "/api/v1"}). Empty means no labels.
