Windows PS client svcs data missing
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.
Thanks!

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.

Sometimes it returns instantly, sometimes it takes 3-4 seconds, but it always returned info. Also, there was no load on the server the last time the report came in blank.
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

Yes, I see those in the report.
Yesterday when the problem was happening I restarted the server… still the same problem after the reboot. Not sure if it makes any difference or not, but mostly where I'm seeing these are VM's running under VMWare.
David.

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…

I don't have a lot of experience with WMI, but it seems like it can be a pretty heavyweight way to get fairly trivial information. There may be some tuning or checks that can be done to make sure it's running as best it can, but a google search or others be able to give better advice than I.
It would also pay to watch the memory footprint of the client long-term. I've tried to do as much preemptive garbage collection as I can, but I'm not convinced there aren't leaks, especially interfacing with COM objects, which given the error above makes WMI a big candidate. I wouldn't be surprised if some of the WMI data could be gained by alternative means such as poking about in the registry, but I don't have time to investigate at present.

I wouldn't be surprised if some of the WMI data could be gained by alternative means such as poking about in the registry, but I don't have time to investigate at present.

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.

Thank you Raymond… If I knew how to implement it I would. Hopefully David or Henrik can find the time to experiment with it.
I'm seeing all kinds of problems with the PS client…. If this keeps up I'll have to remove it. It pegged one of my servers at 100% for over an hour, stuck on the WMI yesterday.

Scot,
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
Looks like it's a problem with your system.
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…
I don't have a lot of experience with WMI, but it seems like it can be a pretty heavyweight way to get fairly trivial information. There may be some tuning or checks that can be done to make sure it's running as best it can, but a google search or others be able to give better advice than I.
It would also pay to watch the memory footprint of the client long-term. I've tried to do as much preemptive garbage collection as I can, but I'm not convinced there aren't leaks, especially interfacing with COM objects, which given the error above makes WMI a big candidate.

Ray,
Thanks for the code. I’m a bit wary of using something with such a version specific path though – is that seriously a “standard” interface to a .Net DLL that can be expected to have some degree of persistence?
I’m offsite this week, will try to take a look next week.
Thanks, David.

Scot,
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. ☺
The CPU spike could be the event log reporting – I don’t actually use that part of the client myself (there is a switch to disable event log reporting completely). Get-EventLog cmdlet is very braindead and scans the entire event log every time it runs (the –since “filter” does not use any indexing as far as I can tell on any version of Windows). I forward my event logs with SNARE to a central syslog server and then use winevtmsgs which I have added to xymonton. I did have a go at using .Net to properly “tail” the event logs, but didn’t get that finished to add to the client. Might take another look at that when I get a chance.
David.

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!

David,
I don't really need the event reporting, it's just a nice-to-have. I'll try disabling it and see if it reduces the load.

Scot,
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
The CPU spike could be the event log reporting – I don’t actually use that part of the client myself (there is a switch to disable event log reporting completely). Get-EventLog cmdlet is very braindead and scans the entire event log every time it runs (the –since “filter” does not use any indexing as far as I can tell on any version of Windows). I forward my event logs with SNARE to a central syslog server and then use winevtmsgs which I have added to xymonton. I did have a go at using .Net to properly “tail” the event logs, but didn’t get that finished to add to the client. Might take another look at that when I get a chance.
David.

David,
It doesn't keep the client from spiking the CPU to 100%, but it does return to normal in half the time now. I'm wondering if the rest of that is the WMI call for services.
