Ever wanted more different ways to understand what’s going on in a program? Here I catalogue a huge variety of tracing methods you can use for varying types of problems. Tracing has been such a long-standing interest (and job) of mine that some of these will novel and interesting to anyone who reads this. I’ll guarantee it by including 2 novel tracing tools I’ve made and haven’t shared before (look for this: Tooling drop!). What I see as the key parts of tracing are collecting timestamped data on what happened in a system, and then ideally visualizing it in a timeline UI instead of just as a text log. First I’ll cover my favorite ways of really easily getting trace data into a nice timeline UI, because it’s a superpower that makes all the other tracing tools more interesting. Then I’ll go over ways to get that data, everything from instrumentation to binary patching to processor hardware features. I’ll also give a real-life example of combining eBPF tracing with Perfetto visualization
