There seem to be issue in naming conventions. We need to review naming conventions used by Prometheus exporter plugin and fix or match it to expected metrics that we want to track. I will look at this.

I renamed the title as its really certain expected metrics are not there but I believe its a misunderstanding of expectations.  Additionally, lowering the priority as we can pull metrics and just need to understand what info is available.

From "ES-Prometheus naming" sheet of [1], openshift.logging.elasticsearch.disk_used = sum(es_fs_path_total_bytes - es_fs_path_free_bytes)

we have separated es_fs_path_total_bytes and es_fs_path_free_bytes metrics,
do we have one separated metrics for openshift.logging.elasticsearch.disk_used, instead of calculate it by sum(es_fs_path_total_bytes - es_fs_path_free_bytes)?
