Metrics emitted from applications might contain parameters (i.e., tags or labels) for which a specific metric is measured. Micrometer provides a facade over the instrumentation clients for many widespread monitoring systems like Atlas, Datadog, Graphite, Ganglia, Influx, JMX, and Prometheus. This article’s scope explores some extra practices when combining Micrometer and Quarkus to tailor those metrics or give you some ideas of what you could extra measure.

For simplicity and given Prometheus popularity, the Micrometer Prometheus registry will be used as an example to demonstrate most of the use cases.
