Monitoring addon not working on Springboot

[r00ta]

Hi,

I'm trying to use the monitoring addon on Springboot and apparently the endpoint metrics is not exposed.

How to reproduce:

1) Checkout https://github.com/kiegroup/kogito-examples/tree/master/jbpm-springboot-example 2) add the dependency

    <dependency>
      <groupId>org.kie.kogito</groupId>
      <artifactId>monitoring-prometheus-addon</artifactId>
    </dependency>

To the pom.xml And create the class ProcessEventListenerConfig:

package org.kie.kogito.examples;

import org.kie.kogito.process.impl.DefaultProcessEventListenerConfig;
import org.springframework.stereotype.Component;
import org.kie.addons.monitoring.process.PrometheusProcessEventListener;

@Component
public class ProcessEventListenerConfig extends DefaultProcessEventListenerConfig {

    public ProcessEventListenerConfig() {
        super(new PrometheusProcessEventListener("test"));
    }
}

3) run the app and execute

curl -d '{"approver" : "john", "order" : {"orderNumber" : "12345", "shipped" : false}}' -H "Content-Type: application/json" -X POST http://localhost:8080/orders

4) go to http://localhost:8080/metrics -> endpoint not available.

is it working on quarkus?

[r00ta]

Yep, following the same steps on jbpm-quarkus-example (annotating the ProcessEventListenerConfig with @ApplicationScoped instead of @Component) it works as expected

the problem is caused by configuration for which packages to scan for JAX-RS components

Somehow the prometheus add-on uses wrong package name and due to the cannot be found by default. It's classname is in org.kie.addons... while it should be in org.kie.kogito....

you can workaround this be setting following in 'application.properties'

resteasy.jaxrs.scan-packages=org.kie.kogito.**,org.kie.addons.**

does this still apply? can we fix this in the addon?

[mswiderski]

I'd say it should be fixed in the prometheus-monitoring-addon to use org.kie.kogito as package

this property fix is more of a workaround
