The metrics port here is for Performance Analyzer which utilizes the 9600 port

I wonder if we need to add a new var for other metrics?

@eyenx if we want to use this metricsPort (The metrics port (for Performance Analyzer) that Kubernetes will use for the service) then it should be 9600 right ?

Does the performance Analazer actually expose metrics in prometheus format? If not I would still go for this, ut add 9600 as separate port. How can I enale the performance Analyzer plugin?

So I enabled the plugin following the guide, but I still see no metrics when I try to curl the Port

I think when you enable PA you would need to query through 9600

Description
Trying to figure out how to expose metrics, it was obvious that there is the need of installing an additional plugin to be able to expose prometheus metrics over the serviceMonitor. Also the default port exposing the metrics is 9200 and not 9600.
This fixes the default metricsPort and adds a comment about the plugin to be used in
