/usr/bin/samply

samply is a sampling CPU profiler.
Run a command, record a CPU profile of its execution, and open the profiler UI.
Recording is currently supported on Linux and macOS.
On other platforms, samply can only load existing profiles.

EXAMPLES:
    # Default usage:
    samply record ./yourcommand yourargs

    # On Linux, you can also profile existing processes by pid:
    samply record -p 12345 # Linux only

    # Alternative usage: Save profile to file for later viewing, and then load it.
    samply record --save-only -o prof.json -- ./yourcommand yourargs
    samply load prof.json # Opens in the browser and supplies symbols

    # Import perf.data files from Linux perf:
    samply import perf.data
