Need Help on Set Up Management Agents to Collect Metrics in Prometheus Format

Summary:

I have tried the following steps documented at https://docs.oracle.com/en-us/iaas/management-agents/doc/deploy-management-agents-prometheus.html

There were no errors in the setup. All the steps went through.

I couldn't find new metric namespace "poc_prometheus" by navigating to OCI -> Observability & Management -> Monitoring -> Metric Explorerer. Where can I find this new metric space? Please help me in traiging this issue.
