For a host with 2 CPU packages of 24 cores each, when I call /api/resources/stats to get cpu|usage_average there are 49 return values: one cpu:<i>|usage_average per core, plus cpu|usage_average. How are these related? Is cpu|usage_average the mean of the cpu:<i>|usage_average?
I can answer part of my own question: no, cpu|usage_average is NOT the mean of cpu:<i>|usage_average. I found a timestamp for which cpu:<i>|usage_average is never greater than 70.76 (mean is 54.63) but cpu|usage_average is 98.74.
