Ruby OpenTracing Instrumentation
To set up Datadog with OpenTracing, see the Ruby Quickstart for OpenTracing for details.
Configuring Datadog tracer settings
The underlying Datadog tracer can be configured by passing options (which match Datadog::Tracer) when configuring the global tracer:
# Where `options` is a Hash of options provided to Datadog::Tracer
OpenTracing.global_tracer = Datadog::OpenTracer::Tracer.new(options)
It can also be configured by using Datadog.configure as described in the Ruby tracer settings section.
Activating and configuring integrations
By default, configuring OpenTracing with Datadog does not automatically activate any additional instrumentation provided by Datadog. You will only receive spans and traces from OpenTracing instrumentation you have in your application.
However, additional instrumentation provided by Datadog can be activated alongside OpenTracing using Datadog.configure, which can be used to enhance your tracing further. To enable this, see Ruby integration instrumentation for more details.
| Type | Supported? | Additional information |
|---|
OpenTracing::FORMAT_TEXT_MAP | Yes | |
OpenTracing::FORMAT_RACK | Yes | Because of the loss of resolution in the Rack format, note that baggage items with names containing either upper case characters or - are be converted to lower case and _ in a round-trip, respectively. Datadog recommends avoiding these characters or accommodating accordingly on the receiving end. |
OpenTracing::FORMAT_BINARY | No | |
