Folks,
Perplexing question about load average display with prstat -Z
Solaris 10 OS U4 (08/07)
We have 4 zones with very different processes and workloads..
The prstat -Z command issued within each of the zones, correctly
displays
the number of processes and lwps, but the load average value looks
exactly the
same on all non-global zones..I mean all 3 values (1,5,15 load
averages) are the same
which is quasi impossible given the different workloads..
Is there a bug here?
Thanks,
No, this is correct, unless you have defined resource pools with
separate processor sets on the system all zones will share the same
cpu resources as thus all have the same load average.
If you bind a zone to a pool you will see the load average of the pool
from inside the zone, it can also be observed from the global zone
with poolstat(1M).
Hope this helps.

Henrik Johansson
