Message-Id: <4981F463.1050905@cesmail.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-btrace@vger.kernel.org Is there some documentation on the binary file format out of "blktrace"? I'm interested in writing some post-processing routines that extend what "blkparse" and "btt" do, and there is a substantial disk space hit if I generate the "blkparse" output and post-process that. I'm also considering a network server that takes the binary data from a "blktrace" client and does the analysis "on the fly", rather than saving off a binary trace. A side question ... how likely are changes in the binary format? The language(s) I want to use -- Perl and/or Ruby -- are pretty flexible at re-factoring to match format changes, but I'd like to have a clue on how much maintenance activity I'm taking on. -- M. Edward (Ed) Borasky I've never met a happy clam. In fact, most of them were pretty steamed.
