Or if your python code is already instrumented for OpenTracing, you can simply switch to LightStep's implementation with:
import opentracing
import lightstep
if __name__ == "__main__":
opentracing.tracer = lightstep.Tracer(
component_name='your_microservice_name',
access_token='{your_access_token}')
with opentracing.tracer.start_active_span('TestSpan') as scope:
scope.span.log_event('test message', payload={'life': 42})
opentracing.tracer.flush()When using apache thrift rpc, make sure to both disable use_http by setting it to False as well as enabling use_thrift.
return lightstep.Tracer(
...
use_http=False,
use_thrift=True)This library is the LightStep binding for OpenTracing. See the OpenTracing Python API for additional detail.
