Is there a way to fetch the User CPU Usage as a Percentage directly, having PCP take more than one sample, and doing the rate-conversion itself using the Python API? Currently what I am doing is running pmFetch twice for the "kernel.all.cpu.user". I then calculate the percentage using (val2 - val1) / (timestamp2 - timestamp1) * 100. Is there a way that I can just have PCP do this automatically? This would also be really nice for working with an archive, as I wouldn't have to do this for each and every result that I get.
If there is not a way to get the percentage directly, is there a better way of going about doing this? Thanks, Rohan |
