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:
Figure 1. 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.
