             Summary: Consider to allow non-resuable metrics of the same name in subdeployments
                 Key: WFLY-12854
                 URL: https://issues.redhat.com/browse/WFLY-12854
             Project: WildFly
          Issue Type: Feature Request
          Components: MP Metrics
            Reporter: Ivan Straka
            Assignee: Jeff Mesnil


If two method annotated to use MP Metrics have same name. In case of _Counters_ (example):
* They are reusable there is actually one MP metric and both method invocation are counted to a single metric.
* They are non-reusable:
** They are in the same deployment - ERROR is logged and metrics are not registerd
** They are in different deployments
*** (X) MP Config _mp.metrics.appName_ is used thus metrics are registered under _configured_name;_app=the value_ thus they are registered under different name
*** MP Config _mp.metrics.appName_ is not used - ERROR is logged and metrics are not registerd

Now I'd like to talk about the (X) option. This is valid for two scenarios:
* Multiple deployments
* Deployment with sub-deployments.

In  Multiple deployments I am able to to annotate two methods with non-reusable metric of the same name. However I need to set MP Config _mp.metrics.appName_ property. Then I can select the metric by a tag.

However per https://github.com/smallrye/smallrye-metrics/issues/216 I am not able to do that in deployment with sub-deployments scenario.

This is inconsistent behavior and it would be good to have it implemented.
