Prometheus at http://0.0.0.0:9090

Context

This is an example of distributed tracing with Jenkins based on:

JCasC to configure a local jenkins instance.
JobDSL to configure the pipelines to test the steps.
OpenTelemetry plugin to send traces :)
Maven to send traces for each maven goal.
Ansible to send traces for each ansible task.
Gradle to send traces for each gradle task.
OtelCli to send traces for command.

Further details

It uses the OpenTelemetry Collector to send traces and metrics to different vendors, see https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/examples/demo

Support for ARM64

The docker image of the OpenTelemetry Collector does not support ARM64 arch yet, though there is a workaround, see open-telemetry/opentelemetry-collector-contrib#2379 (comment)

If you'd like to use it then:

Create a Dockerfile in demos/ with the content explained in the above comment.
Edit demos/docker-compose.yml and replace the otel-collector service with the build command.
Proceed with the Run this demo section.
