Microprofile Health in Wildfly 22

[Gunnar Hilling]

I'm porting an existing JEE-Application (ear=ejb+war) to wildfly-22. I'd like to use Microprofile Health. I'm already using Microprofile Config. 

I also added the microprofile-health-smallrye extension and subsystem.

Should I expect the results of custom healthchecks (implemented with health-2.2-api, as provided by wildfly) to appear in "localhost:9990/health"?

Right now I can only "see" the standard checks.

The following code also won't be called when accessing the health-resource:

@Liveness
@ApplicationScoped
public class BaseCheck implements HealthCheck {

@Override
public HealthCheckResponse call() {
return HealthCheckResponse.down("running state");
}
}

Yes, it's expected there, the BaseCheck looks correct to me.

Since you added microprofile-health-smallrye extension and subsystem by yourself, I'd suggest you compare it with standalone-microprofile.xml (wildfly-22.0.0.Final/standalone/configuration/standalone-microprofile.xml).

There is a MicroProfile Health QuickStart at https://github.com/wildfly/quickstart/tree/master/microprofile-health, you can also take a look examples there. Hope this helps.

I noticed that inside EAR it is not supported yet : https://issues.redhat.com/browse/WFLY-12835

Hi Gunnar, were you able to make it work in ear?

I have tried https://github.com/wildfly/quickstart/tree/23.0.2.Final/microprofile-health WAR project on a Wildfly 23.0.2 Final server with provided standalone-microprofile.xml and it works fine when we deploy that web project.

But if I put same project into an EAR and deploy as EAR, then health endpoints only give the default checks. So it seems maybe we need to configure more to make it work inside EAR.

Latest maven ear pom file that I have used (with no success) :
