powershell client blank service list

[Beck, Zak]

Hi

The svcs check is based on this Powershell command:

Get-WmiObject -Class Win32_Service | Sort-Object -Property Name

Occasionally I have seen issues when the WMI repository on the host becomes corrupt and this causes empty results. There used to be a decent Microsoft article on this but they've reorganised everything... I found this:

https://techcommunity.microsoft.com/t5/Ask-The-Performance-Team/WMI-Rebuilding-the-WMI-Repository/ba-p/373846
https://community.spiceworks.com/how_to/21413-rebuilding-the-wmi-repository

I have had some success in the past with the following commands:

winmgmt /verifyrepository

winmgmt /salvagerepository

There's also:

winmgmt /resetrepository

The articles linked above has more info and explanation, obviously, use at your own risk, make sure you have a backup / snapshot etc.

This message is from an EXTERNAL SENDER - be CAUTIOUS, particularly with links and attachments.
________________________________

I have one 2016 server that is running the 2.42 version of the powershell client and it's intermittently returning nothing for the svcs check, so I get a blank section like below, which causes the service check to fail with no matching services.

[svcs]
Name                                    StartupType  Status         DisplayName

If I run it manually it works fine each time. It's happening intermittently - anyone had this before and know what to check? I have tried the 2.27 and 2.42 version of the client and it's happening on both. It's likely related to this specific server but I can't see anything wrong and it has been working for a long time and reporting the services ok.

Regards,

Brandon
