Would love to see this integrate with magic trace . I'll need to look at the code for the flamegraph plugin, because handling nanosecond timestamps in flamegraphs seems to break most tools due to float precision.

As for inner workings, have you looked into magic trace? I want to play around with it but last I checked, it doesn't work on macs.

Absolutely, check out https://github.com/janestreet/magic-trace#privacy-policy and https://github.com/janestreet/magic-trace/wiki/Setting-up-a-.... With a bit of extra configuration, magic-trace can host its own UI locally. You just need to build the UI from source, and point magic-trace to it (via an environment variable).
Apparently it works with virtualization at least with KVM according to https://github.com/janestreet/magic-trace/wiki/How-could-mag......
Broadwell works, Skylake or later works better. We go into more detail about what platforms we support and why in https://github.com/janestreet/magic-trace/wiki/Supported-pla...
They mention that in the privacy section:
We are similarly sad about how unavailable Intel PT is in VMs. In 2022, being unavailable on Macs and VMs raises the barrier to entry extraordinarily high for many people in our target audience. Not sure if working outside of work is your cup of tea, but we've found Intel NUCs to be <$1000 and an unobtrusive way to play with these features at home.
Good point about overhead. I've moved the 2%-10% number front and center, and wrote up a bit more detail about where that comes from in a new wiki page: https://github.com/janestreet/magic-trace/wiki/Overhead
We'll think about adding flame graphs. We unfortunately have little experience writing responsive web UIs, the excellent Perfetto developers did all of the heavy lifting on that front. But who knows, maybe an enterprising Open Source Contributor could help us out. I see Matt Godbolt was asking questions in their discord the other day...
