Journalist

A gem that allows you to look into a running Ruby process.

Motivation

We lack the tools to have real time visibility in Ruby processes. After seeing VisualVM at Baruco, I've realised that a tool like that for CRuby would be amazing. Thus, Journalist was born.

Installation

Add this line to your application's Gemfile:

gem 'journalist'

And then execute:

$ bundle

Or install it yourself as:

$ gem install journalist

Usage

To start profiling, type:

Journalist.start

There are a lot of limitations right now, such as this only working for one process at any given time.
