Increase the count and total of this metric by 1; if 1.0 is less than the current minimum recorded value of the metric, set the new minimum value to be 1.0; if 1.0 is greater than the current maximum recorded value, set the new maximum value to be 1.0. If, however, this metric is not active (i.e., isActive() is false) then this method has no effect. Note that this method is functionally equivalent to update(1).
