OpenTracing

OpenTracing support is included in the ddtrace package. Use pip to install the required opentracing package:

pip install ddtrace[opentracing]

The OpenTracing convention for initializing a tracer is to define an initialization method that configures and instantiates a new tracer and overwrites the global opentracing.tracer reference:

import time
import opentracing
from ddtrace.opentracer import Tracer, set_global_tracer

def init_tracer(service_name):
    config = {
      "agent_hostname": "localhost",
      "agent_port": 8126,
    }
    tracer = Tracer(service_name, config=config)
    set_global_tracer(tracer)
    return tracer

def my_operation():
  span = opentracing.tracer.start_span("<OPERATION_NAME>")
  span.set_tag("<TAG_KEY>", "<TAG_VALUE>")
  time.sleep(0.05)
  span.finish()

init_tracer("<SERVICE_NAME>")
my_operation()

The tracer can now be used like in any other OpenTracing application. See opentracing.io for OpenTracing Python usage.
