Process monitor script?
Hey guys.
My question is pretty simple. I've got a script here that will monitor hard drive usage. Once it gets to 90% i get a snmp alarm. My next project is to monitor CPU usage. With my hard drive script i use df -a to get my hard drive usage in a perl script. Is there any command that will output how much CPU usage is currently being used. Any help is greatly appreciated.

To make things a little bit more clear. This is my Script to send the trap after it checks the hda %. I imagine it only needs to be altered just a little bit to get this to work. I just need to add up the %CPU usage column then send if it's above a certain %....
Code:
#!/usr/bin/perl
$above = 11;
use FileHandle;
use BER '0.58';
use SNMP_Session '0.58';
use SNMP_util "0.54";
@check=`df /dev/hda1`;
##### Checks for lines higher than $above
foreach (@check) {
if (m/(\d+\%)/ and $1 >=$above) {
push @New,$_;
}
}
##### If there is anything found, send trap
if (@New) {
snmptrap("public\@10.64.15.202:162", ".1.2.3.2.1.127.1.0", "localhost", 6, 1,".1.2.3.2.1.127.1.0", "string", "Disk Space Reached $above% full on @New\n!");
}
This one works just fine. Any suggestions on checking CPU usage?
