Apache Sling Commons Prometheus Metrics Exporter

This module is part of the Apache Sling project.

This bundle exposes the collected metrics under the /metrics path and provides the following features:

exports JVM metrics by default
supports multiple MetricRegistry instances

Deployment

The bundle is compatible with prometheus/client-java versions up to 0.10.0. Version 0.11.0 introduced a mandatory dependency on opentelemetry-api, which is not a valid OSGi bundle. This was rectified in version 0.16.0, but unfortunately versions >= 0.15.0 depend on version 4.0 of Dropwizard metrics, which is not supported by the current org.apache.sling.commons.metrics.bundle .

A recommended feature model file for deploying this bundle and additional dependencies is
