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'
