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'
