Block storage tracing in the Linux kernel

Sign up or log in to save this to your schedule and see who's attending!

Is there a mysterious block storage problem you're tracking down? Learn how to use the "blktrace" block tracing mechanism, interpret its (very) detailed output, and use the results to track down driver and/or device problems, and even perform detailed performance analysis. See examples of visualizations of block storage I/O and other extensions of trace data.
