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'
