Configure Service Monitoring

In OpenShift Container Platform, you can enable monitoring for user-defined projects in addition to the default platform monitoring. You can monitor your own projects in OpenShift Container Platform without the need for an additional monitoring solution. Using this feature centralizes monitoring for core platform components and user-defined projects.

In this workshop, user-defined projects monitoring is already enable so you don't need to worry about that. What you need to do is create a Service Monitor resource to tell the platform monitoring what workload/services you want it to monitor.
