# System Resource Monitoring Script. Solaris
# 
# To help you easily gather various system resource usage statistics, you can
# use the following script. This script runs commands such as vmstat,
# iostat, netstat and so on over a specified interval. It places a copy of the
# output in the /tmp directory, where you can examine system resource usage
# statistics in a centralized location. Since this is a simple Korn shell script,
# you can easily modify the script to suit your needs. For example, you can
# change the interval the script uses to sample system activity, the location of
# the output directory, and more.
