Restrictions

  • Delayed Alerts can be used for CAME delay, but not for GONE delay.
  • The delayed alert functionality cannot be used and is not shown for the following alert config types:
    • Multi-instance alert
    • Summary alert
  • The alert delay cannot be used in combination with a value-hysteresis by design.

    Values of all alert config types for which a hysteresis can be used have a drop-down menu that allows selecting a hysteresis for all alert ranges:

    Value Hysteresis
  • If an alert has multiple ranges and an alert delay, and a value falls within a higher range, the delay applies only to the highest range; all lower ranges trigger immediately.
    Note:
    The additional configuration of a time-dependent smoothing (_smooth config) can be used to delay a GONE message.

    By using a time-dependent smoothing (_smooth Config), the timing of a GONE message can be indirectly influenced. The time-dependent smoothing discards all value changes within the smoothing period. A GONE message is therefore triggered only when, after the smoothing period has elapsed, a value change is accepted that moves the value into the good range.
