The System Paging Activity attribute group provides information about factors taking place in your z/OS system that affect system paging rates, including the paging rate, page fault rate, and number of I/O requests waiting for processing.
ASM Queue Length The number of I/O requests waiting to be processed by the Auxiliary Storage Manager (ASM). Valid value is a 4-byte integer.
Datasets Not Operational The number of page datasets that are not operational. This condition can occur if there are a number of I/O errors to the device or the device has not responded to an I/O request. Valid value is a 4-byte integer.

Page Fault Rate The number of page faults per second. A page fault is an interrupt that occurs when an executing program references an address that is not in central storage. Valid value is a 4-byte integer.
System Page Rate The rate at which paging occurs over all storage areas (common, private, and system). Valid value is a 4-byte integer having one decimal position.
Unreferenced Interval Count The time in seconds that the oldest frame of pageable storage has gone without being referenced. Valid value is a 4-byte integer.
