Spring Boot Micrometer Prometheus Metrics Splunk indexing

Introduction

This project shows how to get metrics from Spring Boot, using Micrometer's Prometheus registry, and index those metrics in Splunk through a metrics index.

It uses the Splunk Prometheus App to scrape metrics from Prometheus' /federate API.

See Prometheus Federation

The same principles apply to any metrics that Prometheus can read, not just Spring / Micrometer metrics.

Setup

mvn clean install to build the demo app

docker-compose up to bring up the app, Splunk and Prometheus

Open Splunk UI (admin:password)

You will see the collected metrics in the metrics dropdown on the left side.
