OpManager central server dashboard has not data

OpManager central server dashboard has not data

I installed OpManager v12 in central and probe model. I can setup connection between probe to central.  The inventory added in probe can be shown in central without any issues. but I can not see any device by CPU utilization or others widgets in central dashboard.

the alarms can be found from central without any issues.   Are there any settings I need to verify it?

Or it is the limitation in central server dashboard?

Thank you!
