I'll see what I can do. Thank you so much for replying - this really looks good. Unfortunately I don't have root access and I have to open a ticket in order to have the SA do that and I'm not even sure why I needed this in the first place so I'm not sure I can justify this request or if they'll even run it. I tried myself - here is the contents of nohup.out
dtrace: failed to initialize dtrace: DTrace requires additional privileges
I'll see if I can get in touch with an SA and see if I can get a glimpse of a sample. In any event I appreciate your help as I had never heard of the dtrace programme until now - and I see there's even a long google video on it.
One other thing...a similar command for Linux ? Also, is this dtrace feature realtime or can you search past logs?
