Default control statement member

The following figure shows the default control statement member, CMFMON00.

CMFMON00 is shipped in hilevel.UBBPARM and is used when the C79 parameter is omitted or if it is specified as C79=00.

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

collects data on consumption of resources by TSO address spaces except for real storage

Important

Although RSMDATA=YES is the default, real storage data is very expensive to collect; thus, CMFMON00 sets RSMDATA to NO.

ASD STATUS=I

collects general information about swapped-in address spaces only

CHANNEL

collects channel path data for all online channel paths

DEVICE CLASS=DASD

collects data on DASD devices only

IOQ

collects data on all I/O queueing activity

PGSPP

collects data on page data set usage

SENQ S,RESOURCE=SYSDSN

collects summary data on the standard enqueues used to serialize data sets

SENQR

collects data on active reserve requests for all volumes

SPAG

collects data on system paging

SRCS

collects data on central storage, processor, and SRM activity
