Have a running Ruby program that you want to profile without restarting it? Want to profile a Ruby
command line program really easily? You want
rbspy! rbspy can profile any Ruby program just by
running 1 simple command.
rbspy lets you profile Ruby processes that are already running. You give it a PID, and it starts
profiling. It's a sampling profiler, which means it's low overhead and safe to run in
rbspy lets you record profiling data, save the raw profiling data to disk, and then analyze it in
a variety of different ways later on.
rbspy supports Linux*, Mac, and Windows.* kernel version 3.2+ required. For Ubuntu, this means Ubuntu 12.04 or newer.
