Traces not showing up in the app¶
The most common reason for traces not being received by Datadog is an agent communication issue:
Ensure the Datadog agent is running and reachable over the network if not on the same host.
ddtraceis configured with the hostname and port of the agent. See Configuration for the configuration variables.
To verify that a connection is being made to the agent, enable start-up logs
with the environment variable
DD_TRACE_STARTUP_LOGS=true. A diagnostic log
that looks like
DATADOG TRACER DIAGNOSTIC... will be displayed with the
connection error if there is a problem connecting to the agent.

Failed to send traces to Datadog Agent...: ConnectionRefusedError(111, 'Connection refused')
The Datadog Agent has a limit to the number of connections it can receive. This can be configured with the instructions here: https://docs.datadoghq.com/tracing/troubleshooting/agent_rate_limits/#max-connection-limit.
