I have played a bit with EBPF on Linux, and it feels weird to use a "packet filter" bytecode-based thing for performance monitoring. Don't we already have a bytecode interpreter in the kernel in the form of Lua? I hardly know anything of Lua, but using that (being an existing tool) would make somewhat more sense than a glorified packet filter (which needs a big tool set in the form of clang to compile C to EBPF bytecode). -Olaf. -- ___ Olaf 'Rhialto' Seibert -- Wayland: Those who don't understand X \X/ rhialto/at/falu.nl -- are condemned to reinvent it. Poorly.
