        Hi Kevin, yes, we noticed the cpu impact on our hosts. Managed to track it down to that particular script using perf.mon etc. over a few hours. Not a problem for a single VM but for a host you will see CPU wait time etc caused by this as all VM's want to run at the exact same time.

        Added a few screen shots. one for a VM and one for the host who struggle the most

        Are you actually seeing CPU impact here in practice, or in theory? Because the simple writing of an event is VERY low CPU impact. Like difficult to measure, low.

        Could probably change:
        Microsoft.SystemCenter.AgentManagement.LogEndToEndEvent

        From :
        <DataSource ID="Scheduler" TypeID="System!System.SimpleScheduler">
        <IntervalSeconds>900</IntervalSeconds>
        <SyncTime>01:00</SyncTime>
        </DataSource>

        To(will need to allow some overrides or hardcode the values instead):

        <DataSource ID="Scheduler" TypeID="System!System.Scheduler">
        <Scheduler>
        <SimpleReccuringSchedule>
        <Interval>$Config/IntervalSeconds$</Interval>
        <SpreadInitializationOverInterval Unit="Seconds">$Config/SpreadTimeSeconds$</SpreadInitializationOverInterval>
        </SimpleReccuringSchedule>
        <ExcludeDates />
        </Scheduler>
