Metrics: http://localhost:8080/q/metrics

Requests to primary resource: http://localhost:8080/resource/1 produces

http_server_requests_seconds_count{method="GET",outcome="SUCCESS",status="200",uri="/resource/{param1}",} 1.0
http_server_requests_seconds_sum{method="GET",outcome="SUCCESS",status="200",uri="/resource/{param1}",} 0.028574045

Requests to sub resource: http://localhost:8080/resource/1/subresource/3 produces

http_server_requests_seconds_count{method="GET",outcome="SUCCESS",status="200",uri="/null/{param2}",} 1.0
http_server_requests_seconds_sum{method="GET",outcome="SUCCESS",status="200",uri="/null/{param2}",} 0.003599618
