Overview

Micrometer is a metrics instrumentation library for JVM-based applications that Apache CXF provides the support for. Starting from Micrometer 1.10, Micrometer provides the Observation API and a plugin mechanism that allows to add capabilities including the tracing features. Starting from 4.0.3 release, the Apache CXF fully supports integration (through cxf-integration-tracing-micrometer module) with Micrometer Tracing distributed tracing capabilities using Micrometer Observation APIs.

The current integration of the Micrometer Observation's distributed tracing in Apache CXF supports Micrometer Observation 1.10.x /  Micrometer Tracing 1.100.x and provides full-fledged support of JAX-RS 2.x / JAX-WS applications. From high-level prospective, the JAX-RS integration consists of three main parts:

Distributed Tracing In Action: Usage Scenarios

TBDIn the following subsections we are going to walk through many different scenarios to illustrate the distributed tracing in action, starting from the simplest ones and finishing with asynchronous JAX-RS services. All examples assume that configuration has been done (see please Configuring Client  and Configuring Server sections above).

Example #1: Client and Server with default distributed tracing configured
