microprofile metrics annotations ignored when using @Named /FISH-300

[demanzano]

Description

---

When a CDI bean is annotated with @Named then its public methods annotated with @Counted or @Metered or @Timed annotations are not considered for Microprofile /metrics/application URL.

Example, these metrics are NOT listed in output.
Just remove @Named and all works fine.

@Path("/mailstatus")
@RequestScoped
@Named
public class MailStatusResource
{
    @POST
    @Path("/")
    @Consumes(MediaType.APPLICATION_JSON)
    @Counted(name="saveMailStatusCounted")
    @Timed(name="saveMailStatusTimed", unit = MetricUnits.MILLISECONDS)
    @Metered(name="saveMailStatusMetered", unit = MetricUnits.MINUTES)
    public void saveMailStatus(@Valid @Size(min=1, max=2_000_000) String data, @Suspended final AsyncResponse resp)
    {
...

Expected Outcome

metrics listed on MP /metrics/application URL output

Current Outcome

no metrics listed on MP /metrics/application URL output, it is empty.

Steps to reproduce (Only for bug reports)

Just add the @Named annotation to any CDI managed class which expose a MP metrics annotation.

Hi,

I can confirm the behaviour that you report in this issue.

I have created the internal ticket FISH-300 to have a closer look at the problem.

Can you indicate why you would like to have the JAX-RS resources also as named CDI beans (as that is uncommon)

Regards
Rudy

hi,

thanks for feedback!

Actually it was an error of my new bean template which include @Named for use with JSF, I simply did not remove it when I created the JAX RS resource. Later I removed the @Named on my JAX-RS bean :-)

Kind regards
Ale
