We have recently  integrated our SCVMM 2012 R2 UR2 box with SCOM 2012 R2 UR2. Since then we are getting a lot of the following errors on our Hyper-V 2012 R2 cluster hosts:

The Microsoft Operations Manager Expression Filter Module could not convert the received value to the requested type. 

Property Expression: Property[@Name='Microsoft:6315F993-63F0-4567-B5B3-165A8BCE9128\83F8638B-8DCA-4152-9EDA-2CA8B33039B4\0\0\L.FreeSpace']

By using the command "Get-VM | Get-VMHardDiskDrive |ft VMName,ID,VMID -Wrap >IDs.txt" we can link the errors to their respective VM. There appears to be errors for ever VM on the box. As you can see in the errors above the hosts are running workflows for 2008 as well as 2012 R2, which seems a bit odd as they're 2012 R2 hosts.

We suspect that the returned value does not match the expected type, i.e. DataItemElementTypeInteger(5). In which case this may be a bug.

Can anyone confirm this?

Many thanks,

Andrew

Please try the cmdlet below to find which monitor encountered this issue:

After getting the monitor name, please ensure the settings are proper; if you can find the related management pack, please also check the management pack settings.

Hi Mai,

Thanks for the reply. Working with our Microsoft support I think we've identified this now as a reproduciblebug in the MP. We are now looking at escalating it to find a resolution that doesn't involve disabling the monitor.

Cheers,

Andrew

Hi Andrew,

Did you find other solution than disabling the monitor?

Thanks,

Jure

Hi Andrew,

Any progress on this?

Hi,

Wow this was a long time ago, and to be honest I can't remember what the fix was in the end. But the alerts have stopped, so this is no longer an issue.

Kind Regards,

Andrew
