Hello u all,

I have time 2 time a need for tracking/monitor supervise application that will keep a track on my running scripts. 2 be more precise, i have a python script that i will like 2 run for like 24/7 under any circumstances. After some investigation i found daemontool, but i do think there is a better tools more , lets say, integrated into linux world like for example corn or at.

Thanks in advance

Spell your words out. And it's "cron", not "corn".

Daemontool appears to be a Windows program...if you're talking about something else, please post a link to the site. The obvious answer (since you wrote the script), is to build some sort of process checker into it, so if the program dies, it will attempt a restart/alert you/take whatever action you want.

If you don't want that, you can check Google for MANY samples for "linux process check script", and see examples like this;

I know, correction as been notified...
Anyway, daemontools is definitively a linux tool check out http://cr.yp.to/daemontools.html made by D. J. Bernstein.

More like apache, sendmail and other, create a main process(monitor process) and use working thread.

Thanks for the info ..

Ahh...well, if it's already written for Linux/Unix...what other 'integration' do you need???
Yes..they usually save a PID identifier somewhere, perhaps in /tmp, with the process ID number of the started daemon. You can do the same with your program, and have a part of your script just watch for that PID. If it's seen, wait and check again in some time. If it's not, attempt a restart, and put in whatever restart logic you want. Personally, I try to restart 3 times, and email an administrator if that happens, and stop trying if you can't get things going in three tries.
