Chapter 1. Enabling observability for Red Hat Developer Hub on OpenShift Container Platform

1. Create the ServiceMonitor CR as a YAML file:

   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     name: <custom_resource_name> 1
     namespace: <project_name> 2
     labels:
       app.kubernetes.io/instance: <custom_resource_name>
       app.kubernetes.io/name: backstage
   spec:
     namespaceSelector:
       matchNames:
         - <project_name>
     selector:
       matchLabels:
         rhdh.redhat.com/app: backstage-<custom_resource_name>
     endpoints:
     - port: http-metrics
       path: '/metrics'

   1

   Replace <custom_resource_name> with the name of your Red Hat Developer Hub CR.

   2

   Replace <project_name> with the name of the OpenShift Container Platform project where your Red Hat Developer Hub instance is running.

2. Apply the ServiceMonitor CR by running the following command:

   oc apply -f <filename>
