Ed,
The most common I have seen is 30 minutes. 15 minutes is also not rare.

minute it occurred
in, was very useful, and being able to correlate to other events.
Note: This can produce a lot of data!

Ed,
in my experience 15 minutes for the most.
I've seen 10 minutes too.
IMHO big SMF DATA producers are DB2, CICS, IMS, MQ etc. with their
accounting records that are not SMF Interval related.
Choosing a maximum of 15 minutes may be better to correlate issues.
Best regards.

In my experience (from many shops / clients over the years), it matches the RMF
interval
and the most common if 15 minutes. Second most common is probably 30 (along
with
RMF) but I think most

With the MQ people - it ranged from 10 minutes up to 1 hour. The default
is 30 mins
MQ 9.3.0 has enhanced its stats and accounting to provide granularity at
.ss - down to the seconds level. See
https://www.ibm.com/docs/en/ibm-mq/9.3?topic=module-using-csq6sysp#q019300___acctime
For example
I do a lot of zCP3000 studies and most customers sending me data seem to be
using a 15 minute interval. I have a couple using 30 minutes (and one 20
minutes), but I prefer 15 minutes for my studies.

Yeah, the stuff I said there, plus... we see data from a lot of systems.
Periodically I sample that data for interesting values, including what the SMF
interval is. Historically that has been 15 minutes for right around 90% of the
systems we see. Next most popular is 30 minutes in about 5% of
Hi Steve,
JWT too low would cause 522s, not 322s.

Check out the peaks in this sample of the same 15 minute SMF data
extracted with 30 and then 15:
