There are many caveats about how reliable this is from the global zone.
- If you have lots of zones, only the ones that consume the most
resources will be listed.
- If a zone is running a workload that has lots of short-lived
processes (software builds, print server, job scheduler, etc.) the
load associated with those short-lived processes will be lost. This
could make a zone that is using 100% of the CPU look nearly idle.

It will be accurate, subject to the limitation that it will only show
the processes in that zone.
