Hello, (My apologies if this issue has been asked before, but I was not able to find any mention of it in the archives).
I recently upgraded from ganglia 3.0 to 3.1 to take advantage of the new multicpu metrics. For CPU usage (e.g. mulitcpu_user0) , I was expecting output like when you run 'top' and hit '1', where maximum possible CPU usage is 100% for each processor. Instead, the ganglia metrics effectively divide the CPU usage metrics by number of CPUs. For example, if there are 2 CPUs, the maximum value of multicpu_user0 seems to be 50%, if there are 4 CPUs, the maximum value is 25%, etc. Is there a reason why the chosen denominator is total time for all CPUs, rather than per CPU like "top"?
