Metrics for stats / host

[iulianroman]

It would be helpful to have some metrics which provide statistics / host, similar to statvlun -rw -d 5 -hostsum -iter 1 command . Only statistics for volumes do not help much when you have many volumes and not a specific naming convention. Not to mention when you have volumes mapped to ESX, it is difficult to drill down without statistics / host.
Also a metric similar to statpd for physical disks.
