HTTP Opentracing

Open Tracing instrumentation for the http gem. By default it starts a new span for every request and follows the open tracing tagging semantic conventions

Installation

Add this line to your application's Gemfile:

gem 'httprb-opentracing'

And then execute:

$ bundle

Or install it yourself as:

$ gem install httprb-opentracing

Usage

First load the instrumentation (Note: this won't automatically instrument the http gem)

require "httprb-opentracing"

If you have setup OpenTracing.global_tracer you can turn on spans for all requests with just:

    HTTP::Tracer.instrument

If you need more control over the tracer or which requests get their own span you can configure both settings like:

    HTTP::Tracer.instrument(
        tracer: tracer,
        ignore_request: ->(request, opts) { request.uri.host == 'localhost' }
    )

Development

After checking out the repo, run bundle install to install dependencies. Then, run rspec to run the tests.
