Getting metrics about Storage Adapters

[Gungazoo]

I've seen a few posts about storage adapters and some mentioned metrics but they weren't new and I haven't been able to get them to work. If I run "Get-Metric -MetricGroup "Storage adapter" |ft -AutoSize" I get the list below but I haven't found out how to query it. I'm mostly looking for latency and contention but I'm sure the solution will apply to all.

advTHANKSance!

You use the Get-Stat cmdlet to query metrics.
With the Get-StatType cmdlet you can see which metrics are available for which entities and in which intervals.
You then use the desired metrics on the Stat parameter of the Get-Stat cmdlet.

I appreciate your help.

I'm sure I'm missing something obvious but I can't guess I can't find the right entity to query. It doesn't appear to be the host which is what I expected. I've tried isolating adapters from the host but I get 'Cannon convert to type "VMware.VimAutomation.Sdk.Types.V1.VIObject"'.

Sorry for being dense.

How did do the call to Get-Stat?
It's hard to give advice without knowing what you are doing

To find out what is available I ran "get-metric -MetricGroup "Storage adapter" which yielded this metric "Storage Adapter Queue Command Latency -- Storage adapter -- ms".

When running "Get-Stat" it requires the "-Entity" with an object passed to it. I'm not sure either/both what object it wants or how to get it. 

I've tried "Get-Stat -Entity $esx" and "Get-Stat -Entity $cluster." I assume it wants the storage adapter as an object but I haven't found how to get what it wants.

I've started with "$stor = get-view (Get-VMHostStorage -VMHost (Get-VMHost -Name <ESX-hostname>)).ID" (that code might look familiar) and pulled pieces from that but no dice. 

I'm sure it is staring me in the face but I must have my eyes closed.

Thanks

You have to use Get-StatType to find the name of the metrics that you can use on the Get-Stat cmdlet.
Storage adapters are connected to the ESXi nodes, so the Entity needs to be an ESXi node.

For example

$esx = Get-VMHost -Name MyEsx

Get-Stat -Entity $esx -Stat 'storageAdapter.read.average','storageAdapter.write.average' -Realtime -MaxSamples 1

Thanks!

I used 

get-stat -Entity $esx -Realtime -MaxSamples 1 -Stat storageadapter*

To show me all of the available stats and the correct name to use which was also a bit confusing when looking at Get-Metric.

Thanks so much!
