One minute MVS performance – getting batch RMF reports

There is an introduction to getting RMF reports docucmented here.

You can display information about your SMF environment, using

D SMF,O

This tells you if you are using SMF datasets, or log streams ( in the coupling facility) for the RMF data.

Copy the data from SMF dataset

// SET SMFPDS=SYS1.S0W1.MAN3 
// SET SMFSDS=SYS1.S0W1.MAN4 
//* 
//SMFDUMP  EXEC PGM=IFASMFDP 
//DUMPINA  DD   DSN=&SMFPDS,DISP=SHR,AMP=('BUFSP=65536') 
//DUMPINB  DD   DSN=&SMFSDS,DISP=SHR,AMP=('BUFSP=65536') 
//* MPOUT  DD   DISP=(NEW,PASS),DSN=&RMF,SPACE=(CYL,(1,1)) 
//DUMPOUT  DD   DISP=SHR,DSN=IBMUSER.RMF SPACE=(CYL,(1,1)) 
//SYSPRINT DD   SYSOUT=* 
//SYSIN  DD * 
  INDD(DUMPINA,OPTIONS(DUMP)) 
  INDD(DUMPINB,OPTIONS(DUMP)) 
  OUTDD(DUMPOUT,TYPE(70:79)) 
  DATE(2020316,2022284) 
  START(0930) 
  END(1700) 
/* 

This job copies the records from the “MAN” data sets, and writes them to the DUMPOUT.

The RMF records with types 70 to 79 are copied, within the specified dates and start and end times.

Copy the data from a log stream.

SMF can write data to log streams, for example MQ records go to the MQ stream, and the RMF records go to the RMF Stream.

//SMFDUMP EXEC PGM=IFASMFDL
//DUMPOUT DD DSN=&TEMP,SPACE=(CYL,(10,10),RLSE),DISP=(NEW,PASS)
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DATE(2018004,2018012)
START(0900)
END(1900)
LSNAME(IFASMF.RMF,OPTIONS(ALL))
OUTDD(DUMPOUT,TYPE(70:79,116))
/*

This step writes the data to a temporary data set.

Sort the data

If you are processing the data from more than one LPAR you will need to sort the data. See here.

Format the RMF data

The RMF control statements are described here

//POST EXEC PGM=ERBRMFPP 
//* use the following if using a temporary data set in same job.
//* MPFINPUT DD DISP=SHR,DSN=*.SMFDUMP.DUMPOUT 
//MFPINPUT DD DISP=SHR,DSN=IBMUSER.RMF 
//PPXSRPTS DD   SYSOUT=*,DCB=(LRECL=200,BLKSIZE=4000) 
//SYSPRINT DD   SYSOUT=* 
//SYSOUT   DD   SYSOUT=* 
//SYSIN DD * 
  SUMMARY(INT,TOT) 
  NODELTA 
  SYSOUT(H) 
  REPORTS(ALL,NOENQ,DEVICE(NOUNITR,NOCOMM)) 
SYSRPTS(WLMGL(RCPER)) 
SYSRPTS(WLMGL(SCPER)) 
/* 
/* SYSRPTS(WLMGL(RCPER)) 
/* SYSRPTS(WLMGL(SCPER,RCLASS,RCPER,SCLASS)) 

This takes the records from MFPINPUT which could be a permanent data set, or a temporary data set passed from a previous job step.

You can have the output go to the spool (by default) or to preallocated data sets. See here

One Minute MVS performance reports of interest are

REPORTS(CPU,DEV(DASD))

For WLM the reports

SYSRPTS(WLMGL(RCPER,SCPER))
