OpenShift 3.11 Prometheus for apps

I'd like to understand how prometheus operator works and how to customize deployment for my needs.

I've decided to use custom prometheus instance base on the operator for apps ? ( is it good approach ? )

Next, I've decided to locate ServiceMonitors in applications namespaces to keep it together with projects. ( is it a good approach ? )


And when I put ServiceMonitor to application namespace Prometheus operator is unable to create prometheus configuration ( no endpoint appears in service discovery, no targets ). How to diagnose this ? What permissions should I set to PrometheusOperator for ServiceMonitor in application namespace? Should I deploy operator with additional container args?

 

Thanks for the help,

Regards,
Arturo
