[Xymon] Windows PS client svcs data missing

Wed May 11 20:19:58 CEST 2011

David,

I was able to catch a system this afternoon that wasn't reporting services.  I get this back when running the get-wmiobject command:

PS C:\> Get-WmiObject -Class Win32_Service

Get-WmiObject :

At line:1 char:14

+ Get-WmiObject <<<<  -Class Win32_Service

    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException

    + FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

One other thing… I noticed that whenever the PS client runs it takes the CPU up to 100% for 5-15 seconds or so on many of the systems it's installed on.  I'm already getting push back from other systems admins because of that.  I imagine many people will be complaining about it sooner or later, that's kind of a bad thing.  J

Off to Google that…

Hi everyone,

I've run into a problem with the Windows Powershell client intermittently omitting service data on Win2008.  Here's the relevant parts of the client data file:

Microsoft Windows Server 2008 R2 Standard   (build 7600)

As you can see, the svcs portion is empty.  I already updated the client to the latest PS client files available and it still is happening. I'm not a programmer so I'm not sure how I can help troubleshoot this, but I'm willing to help in any way I can.

services information is gathered from WMI. The builtin powershell "get-services" doesn't return sufficient information.

Try the following:

open a powershell window (powershell.exe lives in C:\WINDOWS\system32\windowspowershell\v1.0)

Get-WmiObject -Class Win32_Service

Try running it a few times. Is it slow, or does it sometimes not return any information?

Also, if you look at the Client data report (link at the bottom of various pages - cpu, disk, procs, svcs), do you see sections for [WMI:Win32...] towards the bottom of the report. There should be:

WMI:Win32_OperatingSystem
WMI:Win32_ComputerSystem
WMI:Win32_BIOS
WMI:Win32_Processor
WMI:Win32_PhysicalMemory
WMI:Win32_LogicalDisk
WMI:Win32_QuickFixEngineering
WMI:Win32_Product

If these are missing there may be a problem with the WMI service. Try restarting it in the first instance.

David.

Thanks!
