Flamegraph

Flamegraph support for arbitrary Ruby apps.

Note, flamegraph support is built in to rack-mini-profiler, just require this gem and you should be good to go. Type ?pp=flamegraph to create one for the current page.

Installation

Add this line to your application's Gemfile:

gem 'flamegraph'

And then execute:

$ bundle

Or install it yourself as:

$ gem install flamegraph

NOTE: For ruby 2.1+ you'll need to install a stackprof gem:

$ gem install stackprof

Usage

Note: Only supported on Ruby 2.0. Gathering stack traces is too slow on earlier versions of Ruby or JRuby

require 'flamegraph'
html = Flamegraph.generate do
  # your work here
end

# or


Flamegraph.generate(filename) do
  # your work here
end
