   3 Packet logger
   4 =========================
   5
   6 This example shows how to log and print details about query and response.
   7 As soon as the ``iterator`` has finished (event is :data:`module_event_moddone`), ``qstate.return_msg`` contains response packet or ``None``.
   8 This packet will be send to a client that asked for it.

  16 Testing
  17 ------------------
  18 Run the unbound server:
  19
  20 ``root@localhost>unbound -dv -c ./test-log.conf``
  21
  22 In case you use own configuration file, don't forget to enable python module: ``module-config: "validator python iterator"`` and use valid script path: ``python-script: "./examples/log.py"``.
