Overview ¶
Package opentracer provides a wrapper on top of the Datadog tracer that can be used with Opentracing. It also provides a set of opentracing.StartSpanOption that are specific to Datadog's APM product. To use it, simply call "New".
Note that there are currently some small incompatibilities between the Opentracing spec and the Datadog APM product, which we are in the process of addressing on the long term. When using Datadog, the Opentracing operation name is what is called resource in Datadog's terms and the Opentracing "component" tag is Datadog's operation name. Meaning that in order to define (in Opentracing terms) a span that has the operation name "/user/profile" and the component "http.request", one would do:
opentracing.StartSpan("http.request", opentracer.ResourceName("/user/profile"))
Some libraries and frameworks are supported out-of-the-box by using our integrations. You can see a list of supported integrations here: https://godoc.org/github.com/signalfx/signalfx-go-tracing/contrib. They are fully compatible with the Opentracing implementation.
