Are there any docs on how the values for the various stats API's are calculated? (i.e. \_cluster/stats, \_nodes/stats) Most of the values are very self-explanatory, but I'm trying to determine how the nodes.process.cpu.percent value from \_cluster/stats is calculated. If I have 32 total available processors (per nodes.os.available\_processors) does that mean that the percent value of nodes.process.cpu.percent will range from 0% to 3200%?
