  • SCOM Configuration NumSamples and Absolute

     <UnitMonitor ID="FailureCountDelta" Accessibility="Internal" Enabled="true" Target="Server" ParentMonitorID="Performance" Remotable="true" Priority="Normal" TypeID="Performance!System.Performance.DeltaThreshold" ConfirmDelivery="false">
            <Category>Performance</Category>
            <AlertSettings ...>
            </AlertSettings>
            <Configuration>

                     ......
              <Frequency>900</Frequency>
              <Threshold>3</Threshold>
              <NumSamples>1</NumSamples>
              <Absolute>true</Absolute>
           </Configuration>
    </UnitMonitor>

    Frequency: 采样频率,每隔900秒采样一次

    Threshold: 临界值, 与上次采样结果比较,如果差大于该值,trigger alert.

    NumSamples: 采样结果在内存中保存几次,不包含本次采样,如果为1,则表示本次与上次比较,如果为n, 表示本次与上n次的平均值比较。

    Absolute: 与上次比较时是直接取绝对差值,还是取增加或者 减少的百分比。

    Notice:

     Absolute设置项仅在DeltaThreshold类型的monitor中存在, AverageThreshold中是没有的,因为是求平均值,并不取差值。

    AverageThreshold类型常用于响应时间,处理时间的monitor.
