if [ "$( uptime | awk '{print $11}' | cut -d. -f1 )" -gt "10" ]; then echo "too high"; else echo "fine..."; fi
I found this piece of code long time ago in the forum - that's the beginning - add the mail part, use & to run it in the background. Adjust the number 10 to set your own definition of loaded server.
P.S. You don't need to use prstat, uptime is much easier.
Hello,
The last line of prstat shows load average.
I am unable to figure out what actually it is.
I have read the man pages and also googled, all for no use.
Can somebody help me, as to what should be the avg. load of the system for best performance and how is this load of prstat calculated. (6 Replies)

uptime
UPTIME(1) User Commands UPTIME(1)NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
OPTIONS -p, --pretty
show uptime in pretty format
-h, --help
display this help text
-s, --since
system up since, in yyyy-mm-dd MM:HH:SS format
-V, --version
display version information and exit
FILES
