#api_key ⇒ String?

Datadog API key.

For internal use only.

Returns:

  • (String, nil)

end

#env ⇒ String?

The ‘env` tag in Datadog. Use it to separate out your staging, development, and production environments.

Returns:

  • (String, nil)

  o.env Core::Environment::Ext::ENV_ENVIRONMENT
end

#get_time_provider ⇒ Proc<Numeric>

The monotonic clock time provider used by Datadog. This option is internal and is used by ‘datadog-ci` gem to avoid traces’ durations being skewed by timecop.

It must respect the interface of [Datadog::Core::Utils::Time#get_time] method.

For [Timecop](rubygems.org/gems/timecop), for example, ‘->(unit = :float_second) { ::Process.clock_gettime_without_mock(::Process::CLOCK_MONOTONIC, unit) }` allows Datadog features to use the real monotonic time when time is frozen with `Timecop.mock_process_clock = true`.

Returns:

  • (Proc<Numeric>)

    end
  end
end

#service ⇒ String

The ‘service` tag in Datadog. Use it to group related traces into a service.

Returns:

  • (String)

  o.env [Core::Environment::Ext::ENV_SERVICE, Core::Environment::Ext::ENV_OTEL_SERVICE]
  o.default Core::Environment::Ext::FALLBACK_SERVICE_NAME

  # There's a few cases where we don't want to use the fallback service name, so this helper allows us to get a
  # nil instead so that one can do
  # nice_service_name = Datadog.configuration.service_without_fallback || nice_service_name_default
  o.helper(:service_without_fallback) do
    service_name = service
    service_name unless service_name.equal?(Core::Environment::Ext::FALLBACK_SERVICE_NAME)
  end
end

#site ⇒ String?

The Datadog site host to send data to. By default, data is sent to the Datadog US site: ‘app.datadoghq.com`.

If your organization is on another site, you must update this value to the new site.

For internal use only.

Returns:

  • (String, nil)

end

#tags ⇒ Hash<String,String>

Default tags

These tags are used by all Datadog products, when applicable. e.g. trace spans, profiles, etc.

Returns:

  • (Hash<String,String>)

#time_now_provider ⇒ Proc<Time>

The time provider used by Datadog. It must respect the interface of [Time](ruby-doc.org/core-3.0.1/Time.html).

When testing, it can be helpful to use a different time provider.

For [Timecop](rubygems.org/gems/timecop), for example, ‘->{ Time.now_without_mock_time }` allows Datadog features to use the real wall time when time is frozen.

Returns:

  • (Proc<Time>)

#version ⇒ String?
