BigSession

BigSession is a rubygem that helps tracing session over a chain of multiple applications (it's a big session!).

It is inspired heavily by ZipkinTracer, ReuestTracer and general ideas of tracing with slight difference in its concept.

Installation

Add this line to your application's Gemfile:

gem 'big_session'

And then execute:

$ bundle

Or install it yourself as:

$ gem install big_session

Usage

Use BigSession with Rails and Faraday

(It is an only way to use BigSession at the moment.)

Install BigSession to your rails application*s* and put these lines below to your Rails configuration files, config/initializers/big_session.rb for example.

# inbound

::BigSession::RackMiddleware.activate

# outbound

::BigSession::FaradayBigSession.activate

It makes the application receives/generates a big session id for every request.

You can then pass the id to another rails application via HTTP Header (X-Bigse-SessionId) when you use Faraday to send HTTP request.

Check ./example for expected use cases.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
