This extension leverages https://quarkus.io/guides/micrometer[Quarkus Micrometer]. Quarkus supports a variety of Micrometer metric registry implementations.

Your application should declare the following dependency or  one of the dependencies listed in the https://quarkiverse.github.io/quarkiverse-docs/quarkus-micrometer-registry/dev/index.html[quarkiverse documentation], depending on the monitoring solution you want to work with.

[source,xml]
----
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
----

If no dependency is declared, the Micrometer extension creates a `SimpleMeterRegistry` instance, suitable mainly for testing.
