hi Luc ,

can you suggest if we can reslolve above error if the destination server has port 5986 open (for https communication)

right now only http(5985)is open .

I'm not sure that will be enough.
Have a look at https://serverfault.com/questions/657918/remote-ps-session-fails-on-non-domain-server  for a more extensive procedure.

tx luc ,i m going to check this it seems this should fix .

i found this video which has almost everthing covered .thought of sharing .

i will check on some test servers if i find any...

That looks like a decent training series.

if you can tell me how to get following from powershell .iam planning to use invoke-command and the script block to get following .

Why Invoke-Command?

You can also do

this is to fetch information from remote systems .

so i want to put code in scriptblock and use invoke-command for multiple computers sessions

something like below .

$multisession=new-pssession -computername com1,com2,com3 -credential $cred

$multisesion will have session to multiple computers here com1,com2,com3

now we can use

invoke-command -session $multisession -scriptblock{code}

Then you just use the Get-WmiObject in the scriptblock, minus the CompterName.

for the time being let me concentrate on cpu part . i think average part will give us the result which are comparable to the data given by most of the tools used to monitor the cpu usage .

is that correct??

$cpu = Get-WmiObject -ComputerName $computerName -Class win32_processor

Yes, the average would be the single value you see in the Task Manager

$sessions=new-pssession -ComputerName com1,com2,com3

invoke-command -Session $sessions -ScriptBlock {

$cpu=Get-WmiObject -Class win32_processor

#$cpu.loadpercentage

$avgcpu=($cpu.loadpercentage | Measure-Object -Average).average

$env:COMPUTERNAME|select @{N = 'cpu percentage usage';E={$avgcpu}}

}

if yu can check the above for cpu (if yu have multiple windows machines) .

I would run it like this

just thought of asking cant we run NE block inside script block.the one i posted ...

is there any thing which is fundamentally wrong??

Not sure what you mean?

What is a "NE block"?

sorry i mean

below kind of expression

$env:COMPUTERNAME|select @{N = 'cpu percentage usage';E={$avgcpu}}

Yes, that is another option, but not in the way you used it.

Like this, it should work

can you please tell me what is "" before pipeline .are we using it because there is no direct property (i.e computername and avgcpu)

""| select @{N='Host';E={$env:COMPUTERNAME}},@{N = 'cpu percentage usage';E={$avgcpu}}

You have to provide an input object (in this an empty string) to the Select-Object.

And then on the Select-Object you can use calculated properties (your NE block :smileygrin:)

Thanks i will be adding memory also .

just thought of checking about pscustomobject as per yur previous code .

found it is modern approach and give cleaner output so following shud work for multiple computers .

since sessions might run parallely so iam using $env:computername for corresponding session .

$sessions=new-pssession -ComputerName com1,com2,com3
Invoke-Command -Session $sessions -ScriptBlock {

$computerName = $env:COMPUTERNAME

$cpu = Get-WmiObject -ComputerName $computerName -Class win32_processor -ErrorAction Stop
$mem = Get-WmiObject -ComputerName $computerName -Class win32_operatingsystem -ErrorAction Stop

[PSCustomObject]@{
    Host = $computerName
    CPU = ($cpu.LoadPercentage|Measure-Object -Average).average
    Mem = [math]::Round(($mem.TotalVisibleMemorySize -$mem.FreePhysicalMemory)/$mem.TotalVisibleMemorySize * 100)

    }

    }
