How does baseline_engine probe use the scalar threshold configuration for dynamic alarms ?
UIM 8.5x
Scalar algorithm for dynamic alarm is calculated and compared on the value which is past the calculated baseline for that particular hour of the day.

If the Baseline is X and configured threshold (Scalar Type) is Y.
The new qos value Q is compared with (X + Y).


scalar algoritm example

If the baseline value for 1PM - 2PM on Tuesday is calculated to be 2.0 , and the dynamic alarm algorithm is set to Scalar and threshold is provided to be >= 7.0 ,then the condition will be breached if the QOS value reported is equal to  9 = (2 + 7) and above.
