What environment variable should you use if you need to send traces to a different socket, host, or port?

DDTRACEAGENTURL overrides the default Agent location and accepts schemes tcp://host:port or unix:///path/to/socket, allowing redirection to any socket, host, or port.

B. Not a recognized Datadog tracer variable.

C. No such environment variable in Datadog instrumentation.

D. Port alone is insufficient; variable is unsupported.
