Parent article: File monitoring with Mortadelo and SystemTap

It's not really right to suggest that the biggest difference between SystemTap and strace is
the GUI.

Strace can only trace one manually selected process or process tree. That makes it less than
useful once you start to involve D-BUS, HAL, kernel interaction, and other sorts of
inter-process communication.

By contrast, systemtap (and FileMon on Windows) can trace a whole system's actions then filter
out uninteresting data.

I like, and use, both.

My point is that the system-wide aspect of systemtap is a vastly more important difference
between it and strace than the Mortadelo GUI is.

You can ask strace to attach as many processes with "-p" as you want.

What it doesn't support is both running a process and attaching to processes (some Idi^Hmisguided person filed a bug about that to Debian and they "fixed" it by removing this functionality that's mentioned even in strace manual page. I have a bug of it in Debian).

You can attach to as many as you want as long as you don't want more than
32 :)))
