We are facing below issues in getting openshift metrices via metricbeat -

  1. We have openshift in our environment and after deploying metricbeat as a daemon set, we are just getting Overview in Kubernetes ECS Dashboard. But we are not getting any data related to controllers, schedulers etc in dashboard.

  2. We just want to get the data of a particular namespace instead of all

  3. Please suggest how we can change the polling interval for metricbeat data from 10 sec to 5 minutes

  4. Openshift internally stores these metrics using node exporter to prometheus then display it in Grafana. How can we directly see it via ElasticSearch/Kibana

  5. Is there any way to join the indices in elasticsearch - like combine the indices of system metrics and kubernetes metrics.

Please help us to resolve above 5 issues.
