If you rule out CPU and MEMORY about the only thing left you want to
consider consumption of is I/O which they do.

Here is what we record currently perhaps that will help your
consideration.  I do record type 99 records and retain them for 5 days.
I needed them once and it was worth having them when IBM asked for them.

Subject: SMF Records recording

Dear folks;

As a possibly a neverending debate, I wanto to know, besides storage and
CPU usage implications, what are the benefits of not having all the smf
records ON with the exception of 4,5 and 99. 

I don't have neither the VSAM SMF records ON nor the CICS record ON. I
run about 10k+ Jobs daily and I have about 25 production CICS regions.

My config are one 2084-303 and one 2084-304 running about 85% capacity.

TIA,

Giovanni
