Stability: 2 - Unstable

This is a description of the tracing points exported for use with tools like
DTrace, ETW, and
SystemTap. If your version of node was compiled
with these enabled you don't need to take any further action in your code to
use them.

Examples

This is not meant to be documentation on how to use a specific tracing
platform. For information on how to use these tools please refer to their
respective documentation.

DTrace

The following is a simple example that will work on Illumos, OS X, and FreeBSD.
It will print the remote IP address, http method, and url for a given request
as it comes in.
