DTrace (in Solaris 10) is a truely marvelous analysis/debugging tool.

No special preparations are needed to examine a program to use DTrace.

The documentation is great!
The into section explains it all much more clearly than I can

It took me about 4 hours from starting with the intro to having a clear
understanding of an apparent network performance problem of a highly
multithreaded program for which I did not have the source.  A problem
that I had not been able to make much headway on with truss in the course
of several weeks of work.

This is sun's starting point

The dtrace engineers blogs have been very useful as well.

I suspect DTrace will be very useful in INN development.
