Relabeling: Rules and Actions

To demonstrate relabeling actions, we will use a simple Prometheus exporter demo application that exports custom metrics with multiple labels. You can run this application locally using Docker.

Install Docker:

curl -fsSL https://get.docker.com | VERSION=27.0 sh

Run the Prometheus exporter demo application:

docker run -d -p 8000:8000 eon01/prometheus-exporter-demo:v0

Test whether the application is running and exporting metrics:

curl http://localhost:8000/metrics
