Thanks you very much Michael for you answer, but the objective of my request is to retrieve this value in a metric in order to trigger an alert if the CPU utilization of a VM exceeds the average utilization CPU of the same VM the last hour.
Firstly i tought about using supermetrics, but if i'm not mistaken, it's impossible to apply the calculation on a specific period. So i have'nt any idea.
I hope to be clear
Regards
