James Lupolt's questions

So there is a lot of guidance on the web that advises tracking the values of the Perfmon counter Hyper-V Hypervisor Virtual processor\CPU Wait time per dispatch as the nearest Hyper-V equivalent of VMWare's CPU ready time.

Unfortunately there does not seem to be much guidance regarding what values of this counter are likely to be problematic, or what range of values is expected on a well-performing system.

My initial thought was that if CPU usage rises at the same time as CPU Wait time per dispatch, this is an indication that there is a CPU bottleneck on at least one guest vCPU.

Is there a better way to interpret this counter? For example, is it possible to convert it to a percentage of time waiting for the CPU?

Is there a reference range of values that Microsoft or Hyper-V practitioners tend to work with?

Could anyone give me an indication of what values they're seeing for this counter on well-performing systems that do not have CPUs oversubscribed?

Thanks!

I'm getting a Powershell error like this:

PS C:\mydirectory> $Error[0]
Get-WmiObject : 
At line:143 char:13
+           $Disk = Get-WmiObject MSCluster_Disk -ComputerName $Resource.OwnerNode -Auth    ...
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
+ FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

Is there a way I can avoid the command that triggered the error (i.e., $Disk = Get-WmiObject MSCluster_Disk ...) being truncated in the error message?

As part of an automated SQL Server installation process, I'd like to programmatically check whether a Windows Failover Cluster has already been validated.

There are some ways to validate the cluster programmatically, such as the Powershell cmdlet Test-Cluster, but I haven't been able to find a way to check the validation status without re-running the validation process, which can be slow and for some tests requires taking disks offline.

Is there a way to check the validation status, such as a property that can be accessed through WMI, the registry, or a Powershell cmdlet?

Is there a way to check whether node interleaving is enabled from within Windows on a Dell R710? omreport chassis biossetup doesn't appear to print any NUMA-related settings on the server I'm looking at.

I'm looking at a server running IIS 7.5 that is throwing generic HTTP 500s for some requests, with no further error reporting or substatus code evident anywhere. So I enabled Failed Request Tracing and the trace report for the failing requests shows a TRIGGER_STATUS of 500 and a FINAL_STATUS of 200. Can anyone explain what the difference between TRIGGER_STATUS and FINAL_STATUS is and why they would not be identical?

The question says it all, I think. I vaguely remember there was an easy way to do this, but don't remember what it was.
