> - IntervalCheckOperator takes max/min ratio of two values for a metric and returns true if it is less than threshold. Currently if one of the values is 0, it assigns the ratio as None. In python comparison None < Number is always true. We should add an option to fail the task if one of the value is 0.
> - Currently it only supports Max/Min. It would be useful to support calculating ratio with relative difference.
