Statement Explanation
RECORD
Sets the global parameters for the recording session.
INTERVAL=1 Data is recorded to the SMF data set once every minute.
RUNTIME=600 Session will run for 10 hours (600 minutes).
Because the SMF=YES|NO parameter is omitted, data is written to the C79OUT
data set by default.
ARD CLASS=T,RSMDATA=NO
Data is collected on consumption of resources by TSO address spaces except for
real storage.
Note that although RSMDATA=YES is the default, real storage data is very
expensive to collect; thus, CMFMON00 sets RSMDATA to NO.
ASD STATUS=I
General information is collected on swapped-in address spaces only.
CHANNEL
Channel path data is collected for all online channel paths.
DDMN
Data on each domain’s consumption of SRM service units is collected.
DEVICE CLASS=DASD
Data on DASD devices only is collected.
IOQ
Data on all I/O queueing activity is collected.
PGSPP
Data on page data set usage is collected.
SENQ S,RESOURCE=SYSDSN
Summary data is collected on the standard enqueues used to serialize data sets.
SENQR
Data on active reserve requests is collected for all volumes.
SPAG
Data on system paging is collected.
SRCS
Data on central storage, processor, and SRM activity is collected.
TRX SUBSYS=STC
TRX SUBSYS=TSO
Data on transactions occurring on subsystems STC and TSO is collected.
