> Key: CXF-9211
> URL: https://issues.apache.org/jira/browse/CXF-9211
> Project: CXF
> Issue Type: Improvement
> Components: JAX-RS
> Affects Versions: 4.2.0, 3.5.11
> Reporter: der-brecher
> Assignee: Andriy Redko
> Priority: Minor
> Fix For: 3.5.0, 3.4.3, 3.3.10

> The JAX-RS micrometer metrics implemented in the PRs listed below generates
> one unique metric per combination of path parameteres in the URL. For
> instance if you have the following path annotation on an API:
> {code:java}
> @Path("/user/{userId}" {code}
> A request to the URL _/user/1234_ will result in the following metric:
> {code:java}
> cxf_server_requests_seconds_count{exception="None",method="GET",operation="getUser",outcome="SUCCESS",status="200",uri="/user/1234",}
> 1.0 {code}
> Since the uri-tag in the metric uses the actual path value this could lead to
> a huge number of metrics since it will create one metric per user. It will
> also be more difficult to aggregate the metrics for one operation in tools
> like Prometheus/Grafana.
> A suggestion is to instead generate the metric with the uri-tag as a
> templated url. I think this is how the metrics generated by Spring MVC is
> constructed. This would result in the following metric instead:
> {code:java}
> cxf_server_requests_seconds_count{exception="None",method="GET",operation="getUser",outcome="SUCCESS",status="200",uri="/user/{userId}",}
> 1.0 {code}
> Not sure if this is possible and what the best solution is, but it might be
> possible to use the UriInfo class
> ([https://javaee.github.io/javaee-spec/javadocs/javax/ws/rs/core/UriInfo.html)]
> to get the URI without the values, or use that class to replace the actual
> values with a placeholder/variable text.
