gruf-zipkin - Zipkin tracing for gruf

Adds Zipkin tracing support for gruf 2.0.0+.

Installation

gem 'gruf-zipkin'

Then in an initializer or before use, after loading gruf:

require 'zipkin-tracer'
require 'gruf/zipkin'

# Set it in the Rails config, or alternatively make this just a hash if not using Rails
Rails.application.config.zipkin_tracer = {
  service_name: 'my-service',
  service_port: 1234,
  json_api_host: 'zipkin.mydomain.com',
  sampled_as_boolean: false,
  sample_rate: 0.1 # 0.0 to 1.0, where 1.0 => 100% of requests 
}
Gruf.configure do |c|
  c.interceptors.use(Gruf::Zipkin::Interceptor, Rails.application.config.zipkin_tracer)
end

This assumes you have Zipkin already setup in your Ruby/Rails app via the installation instructions in the zipkin-tracer gem.

Rails/Rack Tracing

Add this to config.ru, if using above configuration:

use ZipkinTracer::RackHandler, Rails.application.config.zipkin_tracer

Configuration

You can further customize the tracing of gruf services via the configuration:

Gruf.configure do |c|
  c.interceptors.use(
    Gruf::Zipkin::Interceptor,
    span_prefix: 'myapp'
  )
end
