NAME
       dqtool - Display the contents of a disk-buffer file created with

SYNOPSIS
       dqtool [command] [options]

DESCRIPTION
       NOTE: The dqtool application is distributed with the system logging
       application, and is usually part of the syslog-ng package. The latest
       version of the syslog-ng application is available at the official
       syslog-ng website[1].

       This manual page is only an abstract, for the complete documentation of
       syslog-ng, see The Administrator Guide[2].

       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, e.g., 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:

           Disk-buffer state loaded; filename='../var/syslog-ng-00000.qf', qout_length='65', qbacklog_length='0', qoverflow_length='9205', qdisk_length='0'
