Class PrometheusProperties.MetricPropertiesMap

java.lang.Object

io.prometheus.metrics.config.PrometheusProperties.MetricPropertiesMap

Enclosing class:

PrometheusProperties

static class PrometheusProperties.MetricPropertiesMap
extends Object

Map that stores metric-specific properties keyed by metric name in exposition format (underscores instead of dots).

This wrapper makes it explicit that metric names are normalized to underscore format for storage, so that environment variables and properties with dots in metric names can be correctly looked up using normalized names.
