Keeping Count in Jakarta EE Applications with MicroProfile Metrics

MicroProfile is a community driven initiative, built on top of the Jakarta EE Core Profile, that is a collection of abstract specs that form a complete solution to developing cloud native, Jakarta EE microservices.

The MicroProfile Metrics API provides a set of API constructs for exposing different types and kinds of application metrics. With this API, you can expose application, implementation runtime and JVM metrics through annotations and a Java API in the OpenMetrics format, consumable by monitoring applications like Prometheus.

This guide covers the Metrics specification within a Jakarta EE context. By the end of the guide, you will be able to use the Metrics API to expose different kinds of metrics in your cloud-native Jakarta EE application.
