Package org.apache.juneau.rest.server.metrics.micrometer

package org.apache.juneau.rest.server.metrics.micrometer

Micrometer bridge for the juneau-rest-server MetricsRecorder SPI.

This module is opt-in and ships a single class — MicrometerMetricsRecorder — that bridges per-request metric events from juneau-rest-server to a Micrometer MeterRegistry. Consumers wire one as a @Bean MetricsRecorder on their resource and pick the Micrometer registry that matches their downstream (Prometheus, StatsD, JMX, Datadog, NewRelic, etc.).

Containment

The io.micrometer:micrometer-core dependency is declared in provided scope on this module's POM. Consumers that want Micrometer-backed metrics must add micrometer-core themselves at the version of their choice along with their preferred MeterRegistry. This way:

• The core juneau-rest-server jar stays Micrometer-free.
• Services that never opt in pay zero classpath cost.
• Services that DO opt in pick their own Micrometer version (security upgrades, CVE patches) without waiting for a Juneau release.
