OpenTelemetry GraphQL Instrumentation

The OpenTelemetry GraphQL Ruby gem is a community maintained instrumentation for GraphQL. The GraphQL integration activates instrumentation for GraphQL queries.

How do I get started?

Install the gem using:

gem install opentelemetry-instrumentation-graphql

Or, if you use bundler, include opentelemetry-instrumentation-graphql in your Gemfile.


To use the instrumentation, call use with the name of the instrumentation:

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::GraphQL'

Configuration options

OpenTelemetry::SDK.configure do |c|
  c.use 'OpenTelemetry::Instrumentation::GraphQL', {
    # If this option is not provided the default behaviour is to instrument all
    # schemas that extend GraphQL::Schema
    schemas: [MyAppSchema],

    # The following options are disabled by default as they generate
    # large traces, but can be enabled using the following keys to add
    # spans that provide more detail.
    # Further details about what these keys correspond can be found on the [platform_tracing.rb class](
    # enable_platform_field maps to the execute_field and execute_field_lazy keys
    enable_platform_field: false,
    # enable_platform_authorized maps to the authorized and authorized_lazy keys
    enable_platform_authorized: false,
    # enable_platform_resolve_type maps to the resolve_type and resolve_type_lazy keys
    enable_platform_resolve_type: false

Alternatively, you can also call use_all to install all the available instrumentation.

OpenTelemetry::SDK.configure do |c|


An example of usage can be seen in example/graphql.rb.
