Synopsis

:program:`dnstap-read` [**-m**] [**-p**] [**-x**] [**-y**] {file}

Description
~~~~~~~~~~~

:program:`dnstap-read` reads ``dnstap`` data from a specified file and prints
it in a human-readable format. By default, ``dnstap`` data is printed in
a short summary format, but if the :option:`-y` option is specified, a
longer and more detailed YAML format is used.

Options
~~~~~~~

.. option:: -m

   This option indicates trace memory allocations, and is used for debugging memory leaks.

.. option:: -p

   This option prints the text form of the DNS
   message that was encapsulated in the ``dnstap`` frame, after printing the ``dnstap`` data.

.. option:: -x

   This option prints a hex dump of the wire form
   of the DNS message that was encapsulated in the ``dnstap`` frame, after printing the ``dnstap`` data.

.. option:: -y

   This option prints ``dnstap`` data in a detailed YAML format.
