Probe Health Disconnect & All Sensors often grey



Hi PRTG Admin,

Last year, I configuration PRTG & found Probe Health Disconnect & All Sensors often grey, then open case to PRTG (Case PAE1085211) This case already solve by set interval time to 5 minutes for all WMI sensors.

But last week, I found this case came back. My Probe Health Disconnect & All Sensors often grey. I have WMI sensors around 500+. Then I workaround this case by restart server every day, set interval time for all sensors to 10-30 minutes, pause E-mail. How can I should do for this case?

Thanks so much, Pond.
