CPU Utilization Dashboard vs Performance

Hi,

 

I'm trying to monitor CPU performance across LTM devices with version 10.2.4 build 771 HF 6.

 

I notice that the Dashboard CPU stats can rise up very high that worries me somewhat, however when i monitor the performance stats at the same time they remain stable and in line with a 'top' function on the command line.

 

Does anyone know why there is such a difference in output, should i be worried or should i just keep monitoring the performance stats?

 

Cheers Jon

    The busiest processor tends to spike about every 5 minutes to roll up stats, but it is a low priority process ans is only using one core. It is even more noticeable when you have AVR enabled. Its kind of a non issue, but can be alarming.
