Hi All, Dwell time was defined as below in DSP2046_2019.3.pdf
For discrete triggers - The amount of time that a trigger event persists before the metric action is performed For NumericThresholds - The duration the sensor value must violate the threshold before the threshold is activated
In case of discrete triggers, assume if changes happen after 100 second and within a second Metric action will be performed, Dwell time will be 100 or 1 second. If we depend on Metric action time, it will be always few seconds
In case of NumericThresholds , assume if sensor value changes after a day and within a second Metric action will be performed, Dwell time will be 1 day or 1 second
Please explain about the Dwell time attribute and real use case to understand better
Mani, The notion of Dwell Time is the amount of time and situation needs to exists before the situation is deemed to have occurred. Dwell Times are used to avoid 'false' triggers because of jitter (en.wikipedia.org/wiki/Jitter) from sensors or indicators.
In your case of discrete triggers, the start of the dwell time is when the change occurs (after 100s). If the change is sustained for the duration of the dwell time value (e.g. 1s), then the 'change' will be considered to have occurred and the metric action(s) performed. If the change is not sustained for 1s, then the 'change' is not considered to have occurred.
