The Capacity Distribution by Memory graph
The Capacity Distribution by Memory graph displays the percentage and number of partitions whose memory is high, medium, and low capacity relative to the partitions' entitled memory capacity. The Performance and Capacity Monitor designates memory usage as high, if the percentage is 91% or greater, as medium, if the percentage is in the range of 50% - 90%, and low if the percentage is 50% or lower.
