Datadog tracing

Is tracing with datadog agent supported?

I sniffed on port 8126 (tcp) on loopback interface but i never see any traffic destined to 127.0.0.1:8126 (tcp). Datadog agent's tracer sits on 127.0.0.1:8126 (tcp). Datadog specifies they are opentracing compatible.

Thanks.

could you post some logs and possibly give a little more detail on what you did to sniff traffic on 8126?

what are you aiming to achieve by me giving you the log?

So if you're expecting to see tcp traffic, statsd backend at present is udp only.
