💖 dqtool(1) — the dqtool tool manual page 💖

okay so bestie, welcome to dqtool(1), which is a whole manual page from The dqtool tool manual page 💅

---

✨ NAME ✨

dqtool — displays the contents of a disk-buffer file that was created with {{ site.product.short_name }}. 🎀

---

✨ SYNOPSIS ✨

dqtool [command] [options]

---

✨ DESCRIPTION ✨

NOTE: the dqtool application ships with the syslog-ng OSE system logging application, and it's usually part of the syslog-ng OSE package. The latest version of the syslog-ng OSE application lives over on the syslog-ng OSE page. 🦋

ngl this manual page is only an abstract, it's giving teaser-trailer energy. 😭

So like — the dqtool application is a utility you can use to display and format the messages stored inside a disk-buffer file. that's the whole vibe. ✨

🐱 THE CAT COMMAND 🐱

cat [options] [file]

Use the cat command to display the log messages stored in the disk-buffer (also called the disk-queue) file, plus info from the header of the disk queue file. The messages get printed to the standard output (stdout), so you can absolutely use grep and other tools to hunt down particular log messages, for example dqtool cat /var/log/messages.lgs |grep 192.168.1.1. obsessed with that, fr fr. 🔥

The cat command has the following options:

• --debug or -d — prints diagnostic and debugging messages to stderr.
• --help or -h — shows a brief help message.
• --template=<template> or -t — formats the messages using the specified template.
• --verbose or -v — prints verbose messages to stderr.
• --version or -V — displays version information.

🌸 EXAMPLE: 🌸

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

The output looks like:

Disk-buffer state loaded; filename='../var/syslog-ng-00000.qf',
qoutlength='65', qbackloglength='0', qoverflowlength='9205',
qdisklength='0' Mar  3 10:52:05 tristram localprg[1234]: seq:

🚚 THE RELOCATE COMMAND 🚚

relocate [options] [files]

Use the relocate command to move or rename disk-buffer (aka disk-queue) files. Heads up bestie: this option modifies the persist file. 👀

STOP syslog-ng OSE before using this command. like literally stop it first, no cap. 🙈

The relocate command has the following options:

• --all or -a — relocates 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
