check-windows-cpu-load: Get-Counter : Internal performance counter API call failed. Error: c0000bb8

Hi

Unfortunately, the following error message appears under Windows Server 2019 in the plugin check-windows-cpu-load:

outputGet-Counter : Internal performance counter API call failed. Error: c0000bb8. At C:\opt\sensu\plugins\powershell\check-windows-cpu-load.ps1:48 char:32

• 
  + CategoryInfo          : InvalidResult: (:) [Get-Counter], Exception
  + FullyQualifiedErrorId : CounterApiError,Microsoft.PowerShell.Commands.GetCounterCommand

Does anyone have an idea for the solution?

Thanks and Greetings

Thanks for opening an Issue! I will need more info on which version of the check you are running in order to help.

Could you also share the command you are running (with args) and the output?

Can you run the following command without error? Get-Counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 2 -MaxSamples 3

Hi, thanks alot for your answer.

Sure thats the command: "command": "Powershell.exe -NonInteractive -NoProfile -ExecutionPolicy Bypass -NoLogo -File C:\opt\sensu\plugins\powershell\check-windows-cpu-load.ps1 80 90"

These command is running successfully: PS C:\Users\Administrator> Get-Counter -Counter "\Processor(_Total)\% Processor Time" -SampleInterval 2 -MaxSamples 3

Timestamp CounterSamples

Not able to reproduce, are you seeing this across multiple systems? OS Name: Microsoft Windows Server 2019 Datacenter Evaluation OS Version: 10.0.17763 N/A Build 17763 PSVersion 5.1.17763.134 C:\Users\vagrant>Powershell.exe -NonInteractive -NoProfile -ExecutionPolicy Bypass -NoLogo -File C:\opt\sensu\plugins\powershell\check-windows-cpu-load.ps1 80 90 CheckWindowsCpuLoad OK: CPU at 2%.

Hi Derek

Unfortunately, this error is displayed on all 6 server system. They are all the same version:

OS Name: Microsoft Windows Server 2019 Standard OS Version: 10.0.17763 N/A Build 17763 OS Manufacturer: Microsoft Corporation OS Configuration: Member Server OS Build Type: Multiprocessor Free

And they run on different hardware, some are virtualized.

Hi again

it looks like the system could not include perfhelper.ps1.

With Server 2016:

OS Name: Microsoft Windows Server 2016 Datacenter OS Version: 10.0.14393 N/A Build 14393 OS Manufacturer: Microsoft Corporation OS Configuration: Member Server OS Build Type: Multiprocessor Free

everything works:

Powershell.exe -NonInteractive -NoProfile -ExecutionPolicy Bypass -N oLogo -File check-windows-cpu-load.ps1 80 90 CheckWindowsCpuLoad OK: CPU at 0%.

The Powershell versions are differen:

Server 2016. Name Value

PSVersion 5.1.14393.3053 PSEdition Desktop PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...} BuildVersion 10.0.14393.3053 CLRVersion 4.0.30319.42000 WSManStackVersion 3.0 PSRemotingProtocolVersion 2.3 SerializationVersion 1.1.0.1

Server 2019: Name Value

Which Powershell version do you use?

Thanks alot and best regards

Hi again again

I think the problem comes from theComputer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\CurrentLanguage\009\Counter entry

On Server 2016 the values are as follows:

Processor Information 5196 % Processor Time 5198

On Server 2019 the values are: Processor Information 1896 % Processor Time 1898

But the script still returns the values of the Server 2016.

On Server 2019 at me its look like: 5196 5198 Virtual Disk Pending Deletion Virtual Disk Pending Deletion Bytes

If I enter it manually it works

$Value = [System.Math]::Round((Get-Counter "\Processor Information(_total)\% Processor Time" -SampleInterval 1 -MaxSamples 1).CounterSamples.CookedValue)

Take a look at the Troubleshooting section of the Readme and see if that helps.

[MisterDeeds]

Hi Derek, you mean this?

C:\Windows\SysWOW64>lodctr /R Info: Successfully rebuilt performance counter setting from system backup store

Unfortunately not, still the same error.

[derekgroh]

You'd have to determine the different between your systems as this seems isolated to your environment.

Some troubleshooting steps to explore are to create a base box from disk and see if the issue can be reproduced or test on a vagrant cloud system to gather more information on how your environment could differ.

If you still feel this is an issue related to this code base, please provide as much information to reproduce the issue (including system build) for us to be able to reproduce.
