checking memory and cpu consumption of procs

[Dave Viner]

Here's my first stab at a check_cpu.c program.  I want to use poll() to
watch both stdout and stderr of the child process, but I can't get it to
compile on both FreeBSD and Linux.  FreeBSD just needs:
	#include <poll.h>
but Linux needs:
	#include <sys/poll.h>
	#include <asm/poll.h>

Unfortunately this means that it requires a new definition in configure.in.
I'm not quite sure how to handle that, but I'll also look into make those
changes.  Can anyone help me with that?

Other than that, this program works very well (I think).

thanks

dave

I'll make one for FreeBSD and Linux.  I'll post it to the list when I have
it ready.  Unforunately, I don't really understand autoconf/automake and
configure.in/makefile.am, so I don't know that I'll be able to help much
there....

Thanks !

dave

A check_cpu, based on check_vsz, would be useful. However, it would require
quite a few non-trivial changes to the configure.in and makefile.am to pick
up various flags for the ps command to make it portable. If you want to make
a start, I'd be happy to add in other OSes.
