Daemon to monitor process and inform
 

Hi Unix/Linux Gurus,

I seek your help to create on scrip/daemon or small tool.
Scenario: I have one BPM process which running 24 hours. I need to make script(preferably Daemon) which will be running and monitoring the process activities like memory/cpu consumption. BPM process have memory allocated to created nodes under it. So is there any way like shell/Python/Perl scrip ideas to somehow monitor the process(nodes) details (most importantly memory) and as soon as it has consumed a thresh hold of memory or using zero memory then i can inform via mail or some kinda alert or I can run some other process to deploy a package.


My amatuar thoughts to customize top, htop or to get with in groud with monit(though never used it).
Please need ideas to make this work. and Hope I was able to make my question understandable.

Looking for all kind of inputs!
Thank You,
Singh

Welcome to LQ!

Have a look at http://collectl.sourceforge.net/

Thanks Habitual.
But thats already commercialized tools. I am more keen to right small daemon for my own. so that I can customize and use it as per my requirements.

Any inputs to start with?

1. collectl is free, so not 'commercialized'
2. its written in Perl so if you really wanted to you could read the src if you want to re-invent the wheel.
3. The vast majority of Linux stuff is open src, so you can download & read it if you want to.

(PS: you mean 'write', not 'right')
