Using ftrace (and Other Tools) for Performance Analysis - Steven Rostedt, Red Hat

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

Ever wonder why a tool you used suddenly dropped in performance when upgrading to a new kernel? This can be very difficult to find the exact cause of such a problem. But luckily there are several tools to use to help one out. The first tool to try is perf. perf is well documented as a performance analysis tool. But sometimes that doesn't give you enough information to find the cause of the degradation. Ftrace can give you a different view of the system. This talk will show how to use ftrace and other little known tools of the kernel to find out why a new kernel version has suddenly introduced performance issues to the tools running on top of it.
