This report provides a simple listing of all observations that are considered outliers, including a flag indicating which cluster feature(s) value caused the outlier status. This report can be used to help verify the criteria used for clustering, to identify those cases that should be considered as mainstream, despite the outlier status, and to determine how such cases should be considered in any post-processing efforts.

Figure 3-61. Cluster Performance Index graph Note that in all but one case, the observations were outliers because of abnormal TCB Time usage. Such jobs can be handled either by a special exception job class, or by establishing WLM Service class definitions that manage such jobs in a lower priority scheme, such as making them Discretionary.
