About magic-trace
magic trace is an open source tracing tool, written in OCaml and released under the MIT license, that collects and displays high resolution traces of what a process is doing. It lives in the Linux performance tooling ecosystem and sits alongside perf , which it uses under the hood to drive Intel Processor Trace. Rather than sampling call stacks throughout time, magic trace snapshots a ring buffer of all control flow leading up to a chosen point in time, then renders an interactive timeline of call stacks going back a configurable span of roughly 10ms, at approximately 40ns resolution.
