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.
