Hi Alfredo, you can install openshift-metrics, logging and prometheus afterwards through the openshift-ansible playbooks. Metrics will show you a detailed view in each project how much resources each pod is using, as well as some historical data. Openshift-logging will install an EFK stack and deploy fluentd pods on each host for log aggregation.
I think there should be also the possibility to install the kubernetes dashboard, but I'm not sure. Yes you can install glusterfs afterwards and it's pretty easy to do. There are 2 ways to integrate glusterfs. Either with the openshift-ansible playbooks or with the cns-deploy script. After installing it you also can set glusterfs to automatically create new persisten volumes as soon as a claim is created.
