Unfortunately, I do not know dtrace at all. I've spent the past few hours trying to create something useful out of the existing scripts in /opt/DTT and some examples I found online, but I've been unable to do anything useful (I'm not even 100% sure on what and how I should use those functions..). I got some help in #dtrace on IRC (Freenode), that was useful but did I never got something to work. I grepped for existing dtrace script using the above functions, but was unable to find anything at all, even containing smb_*. Could you provide me with some pointers on how to do this? I've been thinking of different ways of solving this, but I seriously have no idea on where to start, or where to go.
