Top 6 Rust Profiler Projects

Project mention: Strobelight: A profiling service built on open source technology | news.ycombinator.com | 2025-03-07
"All of this is made possible with the inclusion of frame pointers in all of Meta’s user space binaries, otherwise we couldn’t walk the stack to get all these addresses (or we’d have to do some other complicated/expensive thing which wouldn’t be as efficient)"
This makes things so, so, so much easier. Otherwise, a lot of effort has to built into creating an unwinder in ebpf code, essentially porting .eh_frame cfa/ra/bp calculations.
They claim to have event profilers for non-native languages (e.g. python). Does this mean that they use something similar to https://github.com/benfred/py-spy ? Otherwise, it's not obvious to me how they can read python state.
Lastly, the github repo https://github.com/facebookincubator/strobelight is pretty barebones. Wonder when they'll update it
