Aravindan Vijayan commented on AMBARI-17015:
--------------------------------------------
BUG
Since the widgets do not request rate metrics, there could be only be one place
in the code where it could get a negative value.
Currently, in the 2 min window interpolation, we don't reject the negative
values.
FIX
In the interpolation within the 2 minute window, we should sanitize negative
values. That is, if the interpolated value is less than 0, we should omit that.
> Negative values are shown for metrics in certain Ambari widgets.
