Working with the NTNX Powershell cmdlets and struggling to find information regarding the required -metrics argument for the Get-NTNXHostStat cmdlet. Where can the metrics be found?

And for those who are interested, I figured out a way to get the metrics:

The metrics appear to be the same as the stats on the host. This really should've been more simple to find in the documentation though. You can see that the metrics that Chandru referenced "hypervisor_memory_usage_ppm" is available in the list below.

$NTXSvr = Get-NTNXHost
$NTXSvr[0].stats

Here's the resultant list:

Key Value
--- -----
hypervisor_avg_io_latency_usecs 0
num_read_iops 480
$NTXSvr[0].stats

Here's the resultant list:
