we have a nice example setup     

 show the example is configuring a target, return metrics from the service  

The following commands could be added: 

show the serviceMonitor has created a target: 

$ oc -n ns1-coo exec -c prometheus prometheus-example-coo-monitoring-stack-0 -- curl -s 'http://localhost:9090/api/v1/targets' | jq '.data.activeTargets[].discoveredLabels | select(.__meta_kubernetes_endpoints_label_app=="prometheus-coo-example-app")'

return metrics from the service 

$ oc -n ns1-coo exec -c prometheus prometheus-example-coo-monitoring-stack-0 -- curl -s 'http://localhost:9090/api/v1/query?query=http_requests_total' | jq
