SAR Report on Cores/ Threads Per Zone

I am trying to understand the CPU utilization on my server.

its running Solaris 10 in an container (zone)
the physical server has 1 cpu, 4 cores and 2 threads per core.

the zone has been configured to use only 6 threads (3 cores)

So when i run sar -u reports against the zone, i am seeing the CPU is idle 70% most of the time. which i am happy with.

But my question is, does the sar report on only the 6 threads assigned to the zone or all 8 threads available to the CPU?

I cannot say for sar itself without testing, but i would recommend using zonestat and mpstat (check manual for per core metrics).

One could compare the results of those commands to sar output in the same interval and time to answer his own questions.

How did you configure the zone CPU cap ?

Hope that helps
