Hello Radoslaw
if you have a tool to analyze SMF (e.g. SAS/MXG)
you can check which address spaces are using the
zIIP by looking at the SMF30_TIME_ON_ZIIP field in SMF 30 records.
If not, you can run a RMF Monitor I Workload Activity report.
Using the SYSRPTS(WLMGL(SCPER)) ommand you can
check which service classes are using the zIIP.
Using the SYSRPTS(WLMGL(RCPER)) ommand you can
check which report classes are using the zIIP.
Best regards
Fabio

I think one of the points about IPSec is that it is an EMERGENT technology
- in the sense that many sites aren't using it YET. So I regard its zIIP
support to be an ENABLER. Might be time - in many shops - to exploit IPSec
because of this.
(And, static the OBVIOUS, you won't see anything via the PROJECTCPU
mechanism for workloads you aren't running yet.) :-)
That's obvious.
However, how can I see what tasks are using zIIP?
All the zIIP usage peaks (in my environment) are
related to DB2 utils running, but maybe there
are other zIIP exploiters which consume few zIIP
cycles, maybe I'm not aware of some of them. <g>
