[Nagiosplug-help] nagios plugin with perl script

[Kyle Smith]

Here is a link to the nagios plugin developer guidelines - http://nagiosplug.sourceforge.net/developer-guidelines.html 
  - you should read this over first to get some basic ideas down.

For your own purposes you don't need to meet all the requirements  
there, you just need a script that does what you need.

You could change your script to accept values for "warning" and  
"critical" values (look at check_procs syntax, use the -c and -w  
flags) and then compare the amount of free space available to these  
values. Your script should do some basic error checking to ensure the  
warning level is higher than the critical level. If the free space is  
above both values then the script should write "DISK OK" to stdout  
(and more text if you wish) and then exit with a return code of 0  
(meaning everything is fine). If disk space is below warning level but  
above critical level then script should write "DISK WARNING" and exit  
with return code of 1. If free space is below warning and critical  
levels then the script should write "DISK CRITICAL" and exit with  
return code 2. Return code 3 and 4 are for other conditions but can't  
recall them now (you can look this up)..

Now you need to start your coding, you can use almost any language you  
wish.

good luck
