RMF I/O new panel with RATE/response time for ASYN SYNC(zhyperl) CSR (Consistent Read Secondary)

We currently get the I/O response time and and I/O rate by running a RMF report (summary) as follow :

The JCL

//RMFPP EXEC PGM=ERBRMFPP,REGION=0M

//MFPINPUT DD DISP=SHR,DSN=SYTMVS.$SJ08.W9AS3JC.SMF.TOUT.D240128.TKS1

//PPSUM001 DD SYSOUT=*

//PPSUM002 DD SYSOUT=*

//PPSUM003 DD SYSOUT=*

//MFPMSGDS DD SYSOUT=*

//PPXSRPTS DD SYSOUT=*

//SYSIN DD *

SUMMARY(INT)

STOD(0000,2400)

DINTV(0015)

The output looks like this, we get the DASD RESP and DASD RATE that we send to Splunk every 15 minutes.

The values are for each system , the values is calculated by RMF.

We now use CDP to stream SMF records and also RMF reports .

With the introduction of new technology/feature, I think it would be quite interesting and useful for us to have a new RMF panel

that would compute all the different Response_time and IORate that now exist

SYNCH_READ (zHyperlink)

SYNCH_WRITE (zHyperlink)

ASYNH_READ

ASYNCH_READ_CRS (Consistent Read Secondary)

ASYNCH_WRITE

and also a WEIGHTED calculation of the overall SYNCH+ASYNCH RATE and RESPONSE_TIME
