Throttling events (reducing the frequency of events)

Event throttling lets you control the frequency with which the same event is recorded by the event log and appears in the Event Browser, Alarm Monitor, and Windows Event Viewer. Throttling prevents the Event Browser and Alarm Monitor pages, the Windows Event Viewer, and the event logs from becoming overcrowded.

To set event throttling

System > Event Browser

  1. From the Event Browser list box (the box just beneath the Event Browser title bar), change the selection from All Filtered Events to Only Customized Events.
    The Event Browser page changes as follows:

Note/Tip  New is used to customize a specific event, including assigning throttling parameters to a specific event. To set throttling parameters for all events, continue with this procedure.

  1. Click System Throttling.
    The Default System Throttling page appears.

  2. To turn on throttling, choose Enable Throttling.

  3. Specify the Interval and Number values.
    These values determine how often (Number) any event appears in a specified time period (Interval).

    Example

    If you specify 3 as the Number and 60 as the Interval, then any event (for example, 40562) can appear only three times in the Event Browser or Windows Event Viewer in any 60-minute time period. If the event actually occurs five times in a 60-minute time period, the event is displayed only three times.

  4. Click Save.
    The "Only Customized Events" view of the Event Browser appears.

  5. From the Event Browser list box (the box just beneath the Event Browser title bar), choose All Filtered Events.
    The normal view of the Event Browser appears. Changes in System Throttling begin from this point, and are not retroactive.
