GitHub - janestreet/magic-trace: magic-trace collects and displays high-resolution traces of what a process is doing

magic-trace collects and displays high-resolution traces of what a process is doing. People have used it to: figure out why an application running in production handles some requests slowly while simultaneously handling a sea of uninteresting requests, look at what their code is actually doing instead of what they think it's doing, get a history of what their application was doing before it crashe

"The key difference from perf is that instead of sampling call stacks throughout time, magic-trace uses Intel Processor Trace to snapshot a ring buffer of all control flow leading up to a chosen point in time"
