Ruby's MemoryUsageProfiler

Collect memory usage profiling informations from CRuby runtime and Linux pseudo filesystems.

Originally written by @_ko1.

Installation

Add this line to your application's Gemfile:

gem 'ruby-memory-usage-profiler'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby-memory-usage-profiler

Usage

To run profiler itself (without any other ruby code):

$ run_ruby_memory_usage_profiler

This program writes profiler result in 'memory-profile-result' of current directory, in each 1 second.

$ run_ruby_memory_usage_profiler [DURATION sec] [OUTPUT PATH]

For stdout, specify '-'

$ run_ruby_memory_usage_profiler 5 -

From your own code

Kick MemoryUsageProfiler#kick with block how to process results each time you want.

labels = MemoryUsageProfiler.banner
each_time_you_want do
  MemoryUsageProfiler.kick('my_program_label') do |result|
    result_hash = Hash[ [labels, result].transpose ]
    send_to_anywhere_by_myself(result_hash)
  end
end
