[COMPLETE] Daemon/script to record how long a program is run

msalerno · Posted: Wed Jun 14, 2006 2:18 pm Post subject:

After reading the initial post, I wanted to see if I could script it as well. I took the inotify approach.

I used: inotify-tools
It's not in portage
http://rohanpm.net/inotify-tools

You could use something like:

inotifywait -m -e delete -e create /proc/

Which "should" print all create & delete events to the STDOUT. The only problem is that it doesn't work on the /proc filesystem. I tested it on a normal directory and it worked perfectly. This is not an issue with the inotify-tools, I believe it has to do specifically with /proc.

I don't think inotify will be a solution.

I wonder if we should report a bug for this. The whole everything is just a file is only useful if that is really the case

. On the other hand, maybe they have good reasons for this exception.

The thing is that the /proc is it's own pseudo filesystem.

Most likely it doesn't work like a standard fs.

An excerpt from 'sa -a' after allowing accounting overnight; there are actually 77 entries, I just didn't want to post a bunch of noise.

ya i got acct tools to work, but sa -a only prints cpu time, not how long the program was in ram

No - the third column shows CPU time, the 2nd column shows 'real' or 'wallclock' time - what you're looking for.

what is the measurement "re"? seconds or minutes?

ps:

That's where the man page gets a little fuzzy. It looks like seconds to my "experienced" UNIX eye, but specifically the '-j' option states:

the -j option prints out weird output, but i timed it and "sa" alone prints out pretty accurate real time.. so im gonna write a script using perl and awk to organize this nicely

okay finally with the help of my dad, i wrote a very short, useful, and nice looking perl script for this

.. i just dunno what to name it before i publish it.. cmdtime?

Don't know if it would conflict w/anything else, but maybe "runtime". You may want to look a little deeper and see if you can't figure out how to get 'sa' to not consolidate once-run et. al. into those top two lines; that way you could cover all edge cases.

Okay the program is fine, however I want to write a gui for it.. i installed wxperl, but dunno how to print an output of a program or variable... :-\ If anyone could write this.. i would be very thankful

1) Show your code
2) From what you describe this to be, I do not believe a GUI would be beneficial to anyone but a novice. Don't waste your time, unless you have some particular desire for GUI experience.

okay the project is complete (took me about 15-20 hours total of work

and some help from my dad).. its called tcrt (total command runtime), it has a very clean and working gui and also the algorithm has been imporved a lot so that user mistakes would not affect the output of the program and also "all programs" option has been added.. it will soon be posted on sf.net and heres a quick screenie

the gui looks even nicer now

im thinkning if i should add a sort function.. cause you can sort it by time or name.. and these arent columns, so it could be a problem..

okay.. new name: Total Process Runtime (tprt) .. i think thats a lot better especially since this program uses process accounting, not command accounting
