The official Prometheus instrumentation library for JVM applications, providing metric types (counters, gauges, histograms including native histograms), exporters, and an OpenTelemetry OTLP exporter. Version 1.0+ supports concurrent updates, runtime configuration, and a bridge for the legacy simpleclient API.

Use cases

  • instrument a Java web service with Prometheus metrics
  • expose counters and histograms from a JVM application
  • export JVM metrics in OTLP format to OpenTelemetry
  • add native histogram metrics to a Java service
  • monitor a Spring Boot application with Prometheus
  • migrate from prometheus simpleclient to the 1.0 client

When to choose

  • you run JVM services and want Prometheus-native metrics with low-overhead concurrent updates
  • you need OTLP export or runtime-configurable instrumentation in Java
  • you want the official, actively maintained Prometheus Java client

When to avoid

  • you need application metrics in a non-JVM language
  • you want full tracing/logging rather than metrics instrumentation
  • you are locked to the legacy simpleclient API and cannot adopt the 1.0 registry
