Re: How do I get percentage CPU utilization using ssCpuRawIdle?

Thanks Lee....But am not using any third party tool to plot graph....We are
using adobe flex for report module(plotting graph). So, those manipulations
I have to do manually.It will be better for me If I get any idea on
calculating those ticks & all...

Thanks
Malar
