specifies that the I/O domain will be enabled or disabled for event data
collection. An I/O domain is comprised of all real I/O devices. Events in this
domain include such activities as VARY ON and OFF, and attachment and
detachment of devices. You may enable or disable all or selected I/O devices
for the I/O domain. You can restrict them by device number, class type, or
volume.
I/O ALL
specifies that all real devices will be enabled or disabled for event monitoring in
the I/O domain.
I/O CLass class
specifies a list of device classes that will be enabled or disabled for event
monitoring in the I/O domain. class is a list of one or more device classes,
separated by blanks. All real devices of the specified class or classes are
monitored. For a list of classes that can be specified in this command, see
Table 16 on page 623.
I/O DEVice rdev
I/O DEVice rdev1-rdev2
specifies the real devices to be enabled or disabled for event data collection in
the I/O domain. You may specify the device number of a single device; you can
also specify a list, a range of devices, or a combination of both. If you specify a
range, all valid devices in the range, inclusively, are enabled or disabled. For
additional information, see the specific usage notes for I/O.
I/O TYpe type
specifies a list of device types to be enabled or disabled for event monitoring in
the I/O domain. type is a list of one or more device types (such as 3380),

devices of the specified type or types are monitored.
I/O VOLume volid
I/O VOLume CPVOL
specifies a list of volumes that are to be enabled or disabled for event
monitoring in the I/O domain. volid is a list of one or more volume identifiers,
separated by blanks. If CPVOL is specified, all CP-owned volumes will be
enabled or disabled for monitoring. A CP-owned volume is any volume specified
on the CP_OWNED statement in the system configuration file. For devices
identified by DEVNO, you cannot use the volume option of Monitor. The volume
option can only be used for devices identified by VOLSER.
PROCessor
specifies that the PROCESSOR domain will be enabled or disabled for event
data collection. Events such as VARY ON or OFF of a processor are monitored.
SCHeduler
specifies that the SCHEDULER domain will be enabled or disabled for event
data collection. Event data include such statistics as scheduler queue
manipulation, flow of work through the system, and resource allocation
strategies of the scheduler and the dispatcher.
SCHeduler ALL
