Tracing the Kernel: Advanced Usage of Ftrace - Steven Rostedt, Red Hat

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

Ftrace is the official tracing infrastructure of the Linux kernel. Most developers use it on a daily basis to help them understand how their code interacts with the rest of the kernel. System administrators use it to see how the kernel impacts performance on the system. Most people have a basic idea on how to use ftrace, but very few people know its full potential. This talk will go into some of the more advance features, like snapshots, back traces, graph tracing, stack tracer, trace markers, kprobes, multiple instances and much more. Ftrace came into the Linux kernel in 2009 and has continued to grow in features. This talk will explain the depths of what ftrace can do, and what it may do in the future.
