Metrics not being collected from jolokia endpoint

[viv816]

Hi,

I have created a test project on an Openshift cluster (1 master, 1 infra, 2 nodes).

Then pulled and deployed latest "hawkular/hawkular-openshift-agent" image to my project and config map 'hosa-config.yaml' as environment variable.

I also deployed a docker image of a spring boot application containing camel routes with jolokia enabled and config map 'app-config.yaml' as environment variable.

However, the 'hawkular-openshift-agent' pod does not seem to collect metrics from my spring boot application. Log details shown below.

Did I miss any step or configuration? I am new to openshift. I tried the instructions mentioned in the readme file, but got same logs. Please help.

(Btw, the spring boot application logs show everything is fine and all camel routes are started and all metrics endpoints are mapped and jolokia listening on 8080.)

Thank you,

Make sure you have ConfigMap as volume on your springboot application and the volume name must be hawkular-openshift-agent where you specify the metrics to be collected.
