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
