I'm trying to run some tests so I can find locally relevant numbers,
but I was wondering if you had any idea what sort of performance hit
I'd be incurring by logging every successful execve.
To be sure, I consider this a bad idea and I'm actually looking to
disuade people of it.
Cheers,
peter

It is a bad idea. Think of shell scripting.You can get 100s of execve's for just
one command on a command line. You'll never find what you think you wanted. I
think we did some testing over 5 years ago. There was a micro-benchmark here:
http://people.redhat.com/sgrubb/files/lspp-perf.tar.gz
I think it was testing the access syscall. But you can substitute what you want.
I have not benchmarked the audit system in years.
