Error when Querying WMI Namespace: root/MSCluster

[Doug5]

I am getting this error in the MID Server log file (and in the Pattern Log). See ERROR below.

I ran some PowerShell (see below) to investigate this issue. My Question is Why is the Pattern querying the WMI Namespace root/MSCluster for most or all Windows Servers? This seams unnecessary and is causing unnecessary errors.  You can see from my PowerShell output  for WMI QUERY 1 that this Namespace does not exist. The Pattern should perform Query 1 first for all Windows Servers - and should only query root/MSCluster if this namespace is found to exist.

Have I made a mistake?  Any thoughts?

Within pattern designer, there is a debug mode available. It's a button at the top of the pattern designer window that you can select and choose a MID and device to debug the pattern against.

Hey @Doug5,

Have you checked if the account you use for discovery has access to the WMI namespace (root\MSCluster)

Try this query from your MID, this will tell you if that namespace is available. If this is available, then probably there is no proper access permissions to the namespace.

Get-WmiObject -Namespace "root" -ClassName __Namespace -Credential <name_of_the_account> -ComputerName <remote_host_name> | foreach Name

Let me know if you are able to find something with this.

Yes.  I have thank you.  I did run that Query.  See my PowerShell script above.  The Output from my PowerShell indicates that the child Namespace  root/MSCluster does not exist - so my Question is: Why is the pattern trying to query root/MSCluster when it does not exist?

[Doug5]

Thank you.  I will take a look.
