Hi,
Would you be open / interested in adding lightswitch as one of the available profilers? I thought of posting here after lurking in Rust's zulip and seeing some mentions of the issues of dealing with other profilers (cc @bal-e).
The TL;DR is:
- x86_64 and arm64 Linux only, frame pointers not necessary;
- support deeper stacks thanks to not using
PERF_SAMPLE_STACK_USER, as of now, no limits in terms of process stack, and up to 200 user + kernel frames;
- various output modes, including to the Firefox profiler, SVG flamegraph, Perfetto, and others;
- written in Rust :)
I think right now the biggest blocker compared to other profilers is that it doesn't accept a command to run and profile, it can either profiler the whole box of the specified pids. This is something I am planning on adding soon and can prioritise if this would be useful.
