8007 on Windows 2003 server - In my dashboard I have a top 10 CPU utilization widget and a top 10 memory usage widget.  For some reason in looking at that dashboard today I noticed that the top 10 data is no longer displayed.  However, as long as the specified period for the widget is anything but today, 24 hour, or 12 hour it will display graphical data.  My questions is why is data suddenly not available for those periods?

 

I assume this data is developed through the reporting tool as it exhibits the same problem.  

 

Your insights are appreciated.
