TOP 10 CPU Utilization, Hard disk utilization and Memory Utilization does not appear

TOP 10 CPU Utilization, Hard disk utilization and Memory Utilization does not appear

HI,
I am using 8811 OpsManager. I have 9 domain controllers and one router being monitored. When i look at dashboard , overview,,, i cannot see the any statistics in TOP 10 widgets (memory, cpu). I tried changing setting from top to all devices but nothing showed. When i go to MAPS->DOMAIN CONTROLLERS-> LIST VIEW, then i can see on rights side the utilization statistics bar.Attached is screen shot.
 
Any idea abou this issue?
