FUNCTION = This DSECT describes the DSA statistics, Storage Manager
state data and the subspace statistics provided by the
Storage Manager.
It is provided for use in users monitoring applications
to map the statistics returned via the statistics exit
or SMF.
An instance of this data area may represent the
statistics for any of the DSAs.
LIFETIME = This data block is created by the storage manager to
hold pagepool statistics, state data and the subspace
statistics. It is released when the request for
statistics has been satisfied.
LOCATION = Caller is passed a pointer to the head of the block.
INNER CONTROL BLOCKS = None
NOTES :
DEPENDENCIES = S/370
RESTRICTIONS = none
MODULE TYPE = Control block definition
