03 Aug 16 Listing IIS Application Pool Memory usage in PowerShell

Open Powershell as an Administrator on the web server, then run:

$apmem= gwmi -ComputerName localhost -NS 'root\WebAdministration' -class 'WorkerProcess' | select PSComputerName, AppPoolName,ProcessId , @{n='RAM';e={ [math]::round((Get-Process -Id $_.ProcessId -ComputerName $_.PSComputerName).WorkingSet / 1Mb) }} | sort RAM -Descending | ft -AutoSize

echo $apmem

You should see something like:

PS C:\Windows\system32> C:\scripts\appool.ps1

PSComputerName AppPoolName ProcessId RAM
-------------- ----------- --------- ---
MYSERVER01 ersinakyuz.com 2352 1150
MYSERVER01 kutuphaneleriseviyorum.org 6184 729
MYSERVER01 perlmonks.com 3444 646

If you get Get-WmiObject : Could not get objects from namespace root/WebAdministration. Invalid namespace then you need to enable the IIS Management Scripts and Tools feature using:

ipmo ServerManager

07 Jan 16 How to troubleshoot memory issues when executing remote Powershell queries

If you are receiving “Processing data for a remote command failed with the following error message: The WSMan provider” message from the PS Queries (e.g. on the Nagios)

All you have to do is log on the target computer, and run powershell with Administrator Rights. Then you can increase Powershell memory with below commands

You can get current memory size with get-item:

Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB

 

And here is the command for change the value:

Set-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB 250 -Force

or

winrm set winrm/config/winrs @{MaxMemoryPerShellMB=”512″}

 

 

In some cases, you need to restart the WinRM service on target system:

Restart-Service winrm
