Hi! I'm one of the maintainers of the Micrometer [1]<https://micrometer.io/> project (together with Tommy Ludwig and Jonatan Ivanov).
I'd like to ask if there would be an interest to introduce the Micrometer Observation API [2]<https://micrometer.io/docs/observation> to Tomcat in order to add metrics and distributed tracing support using a single API (that has no compile dependencies). We will be releasing this API to Maven Central on the 7/11 so it will be publicly available then. We are more than happy to contribute the feature to Tomcat. The Observation instrumentation most likely would include creation of a dedicated Valve similar to the one present in this sample [3]<https://github.com/micrometer-metrics/micrometer-samples/blob/main/mvc/src/main/java/com/example/micrometer/ManualConfiguration.java#L41>.
