You are attempting to access the TotalProcessorTime property for a process that is running on a remote computer. This property is available only for processes that are running on the local computer.

I can't reproduce the sentence because I need to provide credentials or at least that is what I though
>>Get-Process -ComputerName 192.168.1.36
Get-Process : Couldn't connect to remote machine.
At line:1 char:1
Get-Process -ComputerName 192.168.1.36

   ion
    + FullyQualifiedErrorId : System.InvalidOperationException,Microsoft.PowerShell.C
   ommands.GetProcessCommand

So instead i use the Invoke-command cmdlet, passing the necessary credential:
>>  Invoke-Command -ScriptBlock {get-process} -ComputerName 192.168.1.36 -Credential (get-credential)

...

and the result shows correctly the cpu usage, you could try this command.

You are using two different remote methods. The PsRemoting (needed powershell V2 on the both machines) doesn't same that native .Net method(no need powershell on the remote machine).

I've not noticed it before, but I've tried it on a few remote machines, normal and elevated, and I concur: The CPU column is empty.[string](0..9|%{[char][int](32+("39826578840055658268").substring(($_*2),2))})-replace "\s{1}\b"

_{Thursday, November 17, 2011 10:39 AM}

However, you can retrieve the cpu information from remote machines using the win32_process wmi class:

gwmi -Class win32_process -computername some-pc |  select name, kernelmodetime, usermodetime

[string](0..9|%{[char][int](32+("39826578840055658268").substring(($_*2),2))})-replace "\s{1}\b"

Here's something that returns something a bit more useable. (I'm bored, ok, Michal!)

Get-WmiObject Win32_Process | 
select Name, @{Name="CPU_Time";
 Expression={$_.kernelmodetime + $_.usermodetime}} | sort CPU_Time -Descending

[string](0..9|%{[char][int](32+("39826578840055658268").substring(($_*2),2))})-replace "\s{1}\b"

Thanks for your help. I hate to say it, but i knew that. :)

But the question still remains why get-process doesn't work. At least i know its not just in my test environment.

When I run it on my local pc with the -computername parameter, it's not blank.

PS C:\scripts> ps -ComputerName grant-pc | sort cpu -Descending

And, I might add, I've just tested it with Powershell Ver. 3.0, and the issue is the same - blank cpu column when querying remote machines. So it hasn't been fixed. I don't know if this is by design for some reason perhaps.[string](0..9|%{[char][int](32+("39826578840055658268").substring(($_*2),2))})-replace "\s{1}\b"

The following will get you all the info:

Invoke-Command -ComputerName abcde { Get-Process }

Please do not reactivate ancient threads. Especially when they have been answered long time ago.
