The Storage Statistics section includes these fields:

Getmains < 16M: Number of storage Getmains from below the line.
Getmains > 16M: Number of storage Getmains from above the line.
HWM < 16M: Highest amount of storage from below the line.
HWM > 16M: Highest amount of storage from above the line.
Occupancy < 16M: Measure of storage used over time for storage below the line.
Occupancy > 16M: Measure of storage used over time for storage above the line.
HWM of pgm storage < 16M: Highest amount of program storage from below the line.
HWM of pgm storage >16M: Highest amount of program storage from above the line.
HWM of total pgm storage: Highest amount of program storage from above or below the line.
HWM pgm storage cdsa: Highest amount of program storage from cdsa.
HWM pgm storage rdsa: Highest amount of program storage from rdsa.
HWM pgm storage erdsa: Highest amount of program storage from erdsa.
HWM pgm storage sdsa: Highest amount of program storage from sdsa.
HWM pgm storage esdsa: Highest amount of program storage from esdsa.

Occupancy measures the area under the curve of task storage in use against elapsed time. The unit of measure is byte-unit where byte is storage byte and unit is 1024 microseconds. For example, a task occupying 256 bytes for 125 milliseconds (122 units) incurs 31232 byte-units. For more information, see the "Monitoring" topic in the Reference section of CICS Transaction Server.
