Description John Sanda 2014-02-27 02:31:53 UTC

Description of problem:
The Outlier column always renders a value of zero due to a bug in MeasurementOOBManagerBean. The methods,

  * getHighestNOOBsForGroup
  * getHighestNOOBsForResource
  * getSchedulesWithOOBs 

all execute a query to fetch one hour data that is needed in order to compute outliers. That query is executed against the legacy one hour data table in the relational database; consequently, it always returns an empty result set. This in turn produces always produces outliers of zero.

The above methods are also called to render the resource and group OOB Metrics portlet. I have reviewed the code the involved with Mike Thompson. I do not think that the portlets are affected by this because they do not use the outlier property in MeasurementOOBComposite. Mike please chime in here if I am wrong.
