Displaying Zone resource utilization on Solaris 10 with zonestat

A while back I discovered the extremely useful zonestat script for giving dashboard view of the resource utilization across all zones in a system.

Here is a sample of the output from one of our M4k hosting some Oracle zones.

root@testserver # /admin/zonestat_1.4.1.pl -Nl

The VirtualMemory fields is extremely useful on systems which host java applications, as they tend to reserves huge amounts of VM while having a relatively small RSS.

This is usually one of the first utilities I run if I’m trying to track down a memory/swap or cpu issue on a global zone.

It was written by Jeff Victor and unfortunately the project page is gone.

However, I have posted a copy for download here
