NAME
       dqtool --- Display the contents of a disk-buffer file created with {{
       site.product.short_name }}.

SYNOPSIS
       dqtool [command] [options]

DESCRIPTION
       NOTE: The dqtool application is distributed with the syslog-ng OSE
       system logging application, and is usually part of the syslog-ng OSE
       package. The latest version of the syslog-ng OSE application is
       available at the syslog-ng OSE page.

       This manual page is only an abstract.

       The dqtool application is a utility that can be used to display and
       format the messages stored in a disk-buffer file.

THE CAT COMMAND
              cat [options] [file]

       Use the cat command to display the log messages stored in the
       disk-buffer (also called disk-queue) file, and also information from
       the header of the disk queue file. The messages are printed to the
       standard output (stdout), so it is possible to use grep and other tools
       to find particular log messages, for example, dqtool cat
       /var/log/messages.lgs |grep 192.168.1.1.

       The cat command has the following options:

       --debug or -d
           Print diagnostic and debugging messages to stderr.

       --help or -h
           Display a brief help message.

       --template=<template> or -t
           Format the messages using the specified template.

       --verbose or -v
           Print verbose messages to stderr.

       --version or -V
           Display version information.

   EXAMPLE:
              dqtool cat ../var/syslog-ng-00000.qf

       The output looks like: ```config

              Disk-buffer state loaded; filename='../var/syslog-ng-00000.qf',
              qoutlength='65', qbackloglength='0', qoverflowlength='9205',

              ```

THE RELOCATE COMMAND
              relocate [options] [files]

       Use the relocate command to move or rename disk-buffer (also called
       disk-queue) files. Note that this option modifies the persist file.
       Stop syslog-ng OSE before using this command.

       The relocate command has the following options:

       --all or -a
           Relocate every disk-buffer file that is listed in the syslog-ng OSE
           persist file.

       --new_path or -n
           The directory where you want to move the disk-bufffer files. For
           example: /var/disk-buffers

       --persist or -p
           The path to the syslog-ng OSE persist file. The relocate command
           automatically updates the entries of the disk-buffer files in the
           persist file.

   EXAMPLES:
       Relocate a single queue file:

              dqtool relocate --new_path /tmp/dq --persist var/syslog-ng.persist /tmp/syslog-ng-00000.rqf

       Relocate multiple queue files:

              dqtool relocate --new_path /tmp/dq --persist var/syslog-ng.persist /tmp/syslog-ng-00000.rqf /tmp/syslog-ng-00001.rqf

       Relocate every queue file:

              dqtool relocate --new_path /tmp/dq --persist var/syslog-ng.persist --all
