+Select a behavior if you have multiple triggers. Possible values are `max`, `min`, `avg`, or `sum`. The default value is `max`. 
+
+* **max:** - Use metrics from the scaler that has the max number of `queueLength`. (default)
+* **min:** - Use metrics from the scaler that has the min number of `queueLength`.
+* **avg:** - Sum up all the active scalers metrics and divide by the number of active scalers.
+* **sum:** - Sum up all the active scalers metrics.
