If you are not going to use SMF-70 records, you could consider using the
ERBSMFI programming service (see the RMF manual) as part of the information
returned by this API includes the system CPU% busy (from MVS perspective rather
than LPAR view IIRC) and page rate.
Note also that CMF provides an alias to this program as well so that any code
you author for ERBSMFI should work all systems.
If this does not suit your requirements - then I think you are going to have to
roll your own solution.
What exactly are you trying to achieve?
Hi
Trying to get processor utilization values, in smaller intervals , so in
every 5 or 10 seconds, but the RMF SMF 70 record contains
this values for an RMF INTERVAL (minimum 1 minute) , but not for a CYCLE .
I guess the RMF asks for this values in every CYCLE, but the storage SMF
record will be updated/generated at the end of the INTERVAL
Not very clear what they intend to do with this values( I think only to
report), and I agree, it has not too much sense in short periods, on
the other side the challenge is there,
(i.e. to provide something available all other platforms ) .
CPU utilization figures over very small intervals are next to meaningless on
their own (in my opinion) and even sustained high CPU% over long periods could
be OK as long as the WLM goals are being met.

Hi
One important point :
We would like to see this CPU utilization values , in every RMF CYCLE , and not
in every RMF INTERVAL (A CYCLE can be 50millisecond , but the INTERVAL minimum
1 minute ) Can we get this values in a smaller interval ?

A simple calculation of physical CPU usage using SMF-70 :
100*(SMF_interval_stck - SMF70WAT)/SMF_interval_stck
(SMF_interval_stck is the STCK version of SMF70INT)
You can also process the LCPU (logical CPU) sections and work out busy% using
the following fields :
SMF70PDT
SMF70EDT
SMF70WST
SMF70ONT

Hi
Just looking into the SMF 70 records.
Till now don't see the processor usage (or see , just don't understand ) , but
I will try hard

Subject: Processor usage
Hi
My colleagues would like to know the processor usage for every processor on the
machine or on the current LPAR .
Any way to find out something like this: CPU1 was busy 50% in the
last
1 minute and CPU2 was busy in 10%
