process logging

[Aaron_4]

I am trying to find out what and how many processes start when I am running a certain executable. The exec works too fast to just do a ps -ef.

I'm confused! You start a program and you want to know how many processes start? Did you write this application or did someone else??

You could run process accounting or maybe glance will help you?

I think the best thing to do is switch on process accounting temporarily. Switch it on only for the userid you are using to execute the binary (not root as too many other processes running under root). You can easily switch it on using SAM, then run your executable, then switch it off and look at the logs (via SAM) and you will see exactly which/what processes got spawned off.

Aaron,

Here's a little script that might work.

Suppose the process you are interested in is called myProcess. Try the following:

MYPID=`ps -ef|grep myProcess | cut -c 10-14`

ps -ef | grep $MYPID

This should report a list of processes whose parent process is "myProcess"

Good luck!

Harry,
This is one function of a commercial application.

I will look at process accounting and try the script.
