    Hi Everyone.
     
    I need understand why this difference between vmware, cdm and ntperef64.
    I have 300 server discovered with vmware probe with monitoring cpu, disk and memory.
    Of these 300 virtual servers, i have 20 servers of DB with robot installed and cdm, ntperf64 probe. This monitoring show in "CPU Usage" metric a calcule diferent, where the metric for cdm and netperf64 doing match but the vmware probe is different...!!!

    Probe: vmware

    QOS: QOS_VMWARE_VM_CPU_AGGREGATE_USAGE 

    Target: CPU Usage (Average/Rate)

    Probe: CDM

    QOS: QOS_CPU_USAGE

    Target: System

    Probe: ntperf

    QOS: QOS_WIN_PERF

    Target: ProcessorTime/_Total

    If you see the graph the vmware metric is some difference between cdm and ntperf. Why this difference ?
