OpenTracing Tracer implementation for Zipkin in Ruby
Zipkin version >= 2.0.0
Add this line to your application's Gemfile:
require 'zipkin/tracer' OpenTracing.global_tracer = Zipkin::Tracer.build(url: 'http://localhost:9411', service_name: 'echo') OpenTracing.start_active_span('span name') do # do something OpenTracing.start_active_span('inner span name') do # do something else end end
See opentracing-ruby for more examples.
Const sampler always makes the same decision for new traces depending on the initialization value. Set
Zipkin::Samplers::Const.new(true) to mark all new traces as sampled.
Probabilistic sampler samples traces with probability equal to
rate (must be between 0.0 and 1.0). Set
Zipkin::Samplers::Probabilistic.new(rate: 0.1) to mark 10% of new traces as sampled.
After checking out the repo, run
