Windows Update Monitoring - Days passed from last Windows Update randomly going up and down

Hi,

I have a problem with the "Days passed from last Windows Update" monitor in the Windows Update Monitoring template. It randomly goes down, one server at a time, effecting between 2 and 25 servers. I have several hundred other monitors, that all work fine, only this one monitor is showing this behavior.

When I go to component status, I get the following error:

PowerShell script error. Scripting Error: Script does not contain the expected parameters or is improperly formatted. 'Statistic' missing.

Can you tell me how to troubleshoot and resolve the issue?

Thanks,

Mike

Same... Anyone have any updates?

I've found the cause of the error - For some reason around 30 servers are returning null for $objSearcher.QueryHistory(0, 1) so $objEntry is then null causing "$d = $objEntry.Date" to also return null so when it tries to split what should be a date/time (for what appears to be an inelegant way of trimming whitespace) it causes the line to error out with "You cannot call a method on a null-valued expression". I'll look into this some more when I get time but this info might be enough for someone else to jump in with a resolution.
