GraphQL Opentracing
Open Tracing instrumentation for the graphql gem. By default it starts a new span for every request handled by graphql. It follows the open tracing tagging semantic conventions
Installation
Add this line to your application's Gemfile:
gem 'graphql-opentracing'
And then execute:
$ bundle
Or install it yourself as:
$ gem install graphql-opentracing
Usage
First load the opentracing (Note: this won't automatically instrument the graphql gem)
require "graphql-opentracing"
If you have setup OpenTracing.global_tracer
you can turn on spans for all requests with just:
GraphQL::Tracer.instrument
You must also modify your GQL schema to add the ActiveSupportNotifications tracer provided by the GQL gem
tracer(GraphQL::Tracing::ActiveSupportNotificationsTracing)
Under the hood this gem subscribes to graphql instrumentation events through the ActiveSupport notifications framework. If you find the number of spans too noisy you can control which spans are reported though a callback like:
GraphQl::Tracer.instrument(
schema: MyGQLSchema,
tracer: tracer,
ignore_request: ->(name, started, finished, id, data) { !name.include? 'execute_query' }
)
Development
After checking out the repo, run bundle install
to install dependencies. Then, run rspec
to run the tests.
