Description

We would like to have an example for MicroProfile Metrics @Metered annotation.

Here is a quick tutorial on MicroProfile Metrics if you are not aware:

https://www.tomitribe.com/blog/getting-started-with-microprofile-metrics/

Fork / clone the TomEE project from here:

https://github.com/apache/tomee

Example name should be mp-metrics-metered, following the standard already in the project.

All the examples are in:

https://github.com/apache/tomee/tree/master/examples

See this example of @Counted for reference:

https://github.com/apache/tomee/tree/master/examples/mp-metrics-counted

See these two PRs for the diff for @Counted, it will help you see how simple it is:

https://github.com/apache/tomee/pull/203

https://github.com/apache/tomee/pull/207

What you have to do is:

1 - Create a method in the WeatherService class with @Metered

2 - Have a WeatherServiceTest for the GET and OPTIONS scenarios of @Metered

3 - Make sure you have tests for Prometheus and JSON formats

4 - Make sure all the tests pass

After that submit a PR and we'll review it.
