Is your feature request related to a problem? Please describe.

A suite of VSAN related metrics would be useful.

Describe the solution you'd like

I would like to add the following suite of VSAN related metrics:

vcenter.cluster.vsan.throughput       (direction={read/write})
vcenter.cluster.vsan.iops             (direction={read/write})
vcenter.cluster.vsan.cache.hit_rate
vcenter.cluster.vsan.latency.avg      (direction={read/write})

vcenter.host.vsan.throughput          (direction={read/write})
vcenter.host.vsan.iops                (direction={read/write})
vcenter.host.vsan.congestions
vcenter.host.vsan.cache.hit_rate
vcenter.host.vsan.latency.avg         (direction={read/write})

vcenter.vm.vsan.throughput            (direction={read/write})
vcenter.vm.vsan.iops                  (direction={read/write})
vcenter.vm.vsan.latency.avg           (direction={read/write})

The metrics in question will be retrieved from the VsanPerfQuerySpec data object. The following entity types will be used:

• Cluster-related metrics: cluster-domclient
• Host-related metrics: host-domclient
• Virtual machine-related metrics: virtual-machine

For a list of the metrics and their respective details, please refer to the documentation.
