    Bonjour,
    Just have a look to the documentation :

    CPU_ALL :

    "This sheet shows the average utilisation for all physical processors by time of day. Note that for micro-partitions CPU% is a measure of utilisation vs the entitlement but is adjusted by libperfstat so that it never exceeds 100%; this makes the numbers virtually useless for analysis of uncapped partitions and you may choose to look at the charts on the LPAR sheet instead. Note also that micro-partitions generally record very little Idle% or Wait% because they will normally cede their timeslice to other LPARs rather than waste CPU time waiting for work"

    Hope it help
