I am sure many of the Solaris administrators will break their head in an order to find Solaris local zones wise resource utilization details on oracle Solaris 10. Because there is no simple inbuilt tool to find these details in Solaris 10 (Apart from prstat -Z). I just come across Jeff Victor’s Blog and found this script which will be very useful in Unix administration. This script will help you to find resource consumption of each Solaris local zone from the global zone level. Just give a try.
This script will give the following information:
- CPU Pool size
- Capped Physical Memory (aka RAM)
- Used Physical Memory
- Capped Swap space (Virtual Memory aka VM)
- Used shared memory
- Locked Memory
- Used Swap space (aka virtual memory)
Here I will demonstrate how to use this script and explanation about each field in zonestat script output.
Download the zonestat.pl script and make it executable.
Download the zonestat.pl script and make it executable.
Here is the sample output of the script.
bash-3.00# ./zonestat.pl

You have the help option to know each field in zonestat command output.
bash-3.00# ./zonestat.pl -help
Usage: zonestat [-h] | [-l] [interval [count]]
-h: usage information
-l: display columns showing the configured limits
Output with -l option:

Hello,
thank you for writing this script first off.
my question is, I would love to run this script you have written, but I am finding it hard finding the zonestat pkg to install…. Can you point me in the right direction to find zonestat and install that first?
thank you
Paul….
Lingeswaran R says
As per my knowledge,zonestat package available from Solaris 11. For Solaris 10 , you need to use the script what i have attached
