Basic one to check load:

Code:
#!/bin/bash

LOAD_VALUE=`cat /proc/loadavg | sed 's/\./ /' | awk '{print $1}'`

if [ $LOAD_VALUE -gt "6" ]; then
       mail -s “PANIC” someone@somedomain.com
fi



Replace the value "6" for one that apply to you.

getloadavg

getloadavg(3C)						   Standard C Library Functions 					    getloadavg(3C)

NAME

       getloadavg - get system load averages

SYNOPSIS

       #include <sys/loadavg.h>

       int getloadavg(double loadavg[], int nelem);

DESCRIPTION

       The  getloadavg()  function returns the number of processes in the system run queue averaged over various periods of time. Up to nelem sam-
       ples are retrieved and assigned to successive elements of loadavg[]. The system imposes a maximum of 3 samples, representing averages  over
       the  last 1, 5, and 15 minutes, respectively. The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be
       used to extract the data from the appropriate element of the loadavg[] array.

RETURN VALUES

       Upon successful completion, the number of samples actually retrieved is returned. If the load average was unobtainable, -1 is returned  and
       errno is set to indicate the error.

ERRORS

       The getloadavg() function will fail if:

       EINVAL	 The number of elements specified is less than 0.

USAGE

       If the caller is in a non-global zone and the pools facility is active, the behavior of getloadavg() is equivalent to that of pset_getload-
       avg(3C) called with psetid set to PS_MYID.
