trace agent not sending traces to datadog

[anujprashar]

Hi @ivantopo I am using kamon datadog reporter to send metrics and traces to datadog agent running on localhost.
Metrics are sent successfully but traces are not reaching to datadog agent, below is my application.conf.

Kamon Configuration

kamon {

	excludes = [ "**" ]
  }
