I have an anomaly on CPU Utilization monitor for F5-Big-Data machines. It shows 95% CPU usage on OpManager while actual CPU usage for the device is around 20%.

 I've add custom monitor for CPU usage using hostresource mib and the result more accurate. I also deleted Vendor's CPU Utilization monitor. The problem is the new CPU Utilization graph on device snapshot showing No data available.

How can I update the CPU Utilization graph?

Thanks & Regards,
