I've got it about half done at this point. What's still to be done is build the PostgreSQL example and the specialized post-processing code. But the basics -- how to build "blktrace" from source and run it -- are there. It will probably be next weekend before I get a chance to build the PostgreSQL example. http://github.com/znmeb/linux_perf_viz/raw/master/blktrace-howto/blktrace-howto.pdf If anyone wants to comment on it, the best way might be to join Github and send me in-project messages there. I've got some documentation questions I need to ask on the blktrace mailing list. -- M. Edward (Ed) Borasky, FBG, AB, PTA, PGS, MS, MNLP, NST, ACMC(P), WOM I've never met a happy clam. In fact, most of them were pretty steamed. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
