Your Data, Your Rules: Tailoring application metrics with Micrometer
summary
Builds a small pastry-shop microservice that registers a Micrometer counter in a MeterRegistry and increments on each order, exposing metrics via Spring Boot Actuator. Runs a Docker stack with Prometheus scraping the /metrics endpoint and Grafana visualizing trends; the live demo shows a metric value reaching 28 orders and a dashboard threshold that flips red at 20, with expected scraping lag. Code and Docker compose are available on GitHub so the setup actually runs.
