Averaging

Set Averaging for the highlighted metric.

  • Use default - Every value used to calculate a metric's alarm status is obtained by averaging the metric over a period of time specified in Spotlights Options.
  • Don't average this metric - Use the raw metric data retrieved from the current system — anomalies and spikes included.
  • Use custom averaging - Use a moving average, as in the Use default... case, but not the default setting. Set the time period by using the Average over... slider.
  • Average over... - Use the mouse or arrow keys to move the slider and so choose the time period used to generate the moving average. The longer the time period, the fewer the peaks and troughs. Spikes and other anomalies are smoothed.

    Tip: Do not to use too long a time to calculate the moving average. This may prevent the reporting of valid alarms. The maximum time period that Spotlight uses for averaging is five minutes.

Averaging - is a technique that Spotlight uses to smooth out the anomalies and spikes that may appear momentarily in the metric values for a component. The purpose of averaging is to prevent Spotlight from reporting alarms for such spikes if they do not persist.

Notes:

  • Averaging is used ONLY to prevent the generation of spurious alarms. It does NOT affect the charts or tables that display metric values; these continue to display metrics as they are reported.
  • This is not the place to set averaging for all metrics for the connection. Alarm smoothing
