The sinatra tracer does not record the request id

[jamiehodge]

The rack tracer currently adds a request id tag (X-Request-Id header) to each span. It would be nice if the sinatra tracer did the same.

Hey @jamiehodge , would it be reasonable to suggest activating the Rack tracer to get the benefit of this feature (given Sinatra uses Rack)? It would create a Rack span above your current Sinatra span with these tags.

Otherwise, it should be possible to add it to Sinatra without activating Rack, but will require some work on the integration.

@jamiehodge We're planning on releasing 0.13.0 on Wednesday June 20th, which should include support for this via #427. The request ID should appear as a tag on the Sinatra span by default, but you could further configure which headers you'd like to see via the following:

Datadog.configure do |c|
  # Add these request and response headers as tags
  c.use :sinatra, headers: { request: ['Accept-Encoding'], response: ['Content-Encoding'] }
end

Will that work for you?

This should be addressed with our 0.13.0 release. Closing this.
