dtrace discuss - Nov 2007 - Using DTrace to analyse ON build

This is from a discussion on opensolaris-tools that is somewhat relevant for 
DTrace community.

I wrote a simple D script 
(http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/tools/dtrace/dirtrace.d)
that collects data for each dmake process during the Solaris build. After that 
the data is post-processed by a Perl script 
(http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/tools/dtrace/tree.pl)
 that produces a full build timeline for building usr/src/uts (I skipped lib 
and cmd for now). For example, here are

sparc:
http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/Observe/build_76_sun4v_timeline.txt

and

x86:
http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/Observe/build_76_i386_timeline.txt

results. 

It shows when each directory was entered during the build, how much time was 
spent there (inclusive with all subdirectories) and where we came from and 
what targets were used.
