I am using the Python API, and if I run a couple of mgFetch() calls using the MetricGroup class, and then use the metricConvert() function, I end up getting a value likeÂ308.4132647893692. I had thought that to convert this rate converted value to a percentage, all I had to do was multiply by 100, but that would result in 30,800% of the CPU being used, and that is just by the user.Â

Also, these numbers that I am getting don't seem to correspond with the user CPU usage being reported by "top" in terms of a straight multiplication or division at least. It matches "top" when the user CPU usage is 0.0%, but other than that I am not really seeing the correlation. Could anyone point me in the right direction?

Thanks,

Rohan
