SYSLOG-NG(8)		   The syslog-ng manual page		  SYSLOG-NG(8)

NAME
       syslog-ng - syslog-ng system logger application

SYNOPSIS
       syslog-ng [options]

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

       The syslog-ng application is a flexible and highly scalable system
       logging application. Typically, syslog-ng is used to manage log
       messages and implement centralized logging, where the aim is to collect
       the log messages of several devices on a single, central log server.
       The different devices - called syslog-ng clients - all run syslog-ng,
       and collect the log messages from the various applications, files, and
       other sources. The clients send all important log messages to the
       remote syslog-ng server, where the server sorts and stores them.

OPTIONS
       --cfgfile <file> or -f <file>
	   Use the specified configuration file.

       --chroot <dir> or -C <dir>
	   Change root to the specified directory after reading the
	   configuration file. The directory must be set up accordingly. Note
	   that it is not possible to reload the syslog-ng configuration after
	   chrooting.

       --debug or -d
	   Start syslog-ng in debug mode.

       --enable-core
	   Enable syslog-ng to write core files in case of a crash to help
	   support and debugging.

       --fd-limit
	   Set the minimal number of required file descriptors (fd-s); this
	   sets how many files syslog-ng can keep open simultaneously. Default
	   value: 4096. Note that this does not override the global ulimit
	   setting of the host.

       --foreground or -F
	   Do not daemonize, run in the foreground.

       --group <group> or -g <group>
	   Switch to the specified group after initializing the configuration
	   file.

       --help or -h
	   Display a brief help message.

       --no-caps
	   Run syslog-ng as root, without capability-support. This is the
	   default behavior. On Linux, it is possible to run syslog-ng as
	   non-root with capability-support if syslog-ng was compiled with the
	   --enable-linux-caps option enabled. (Execute syslog-ng --version to
	   display the list of enabled build parameters.)

       --persist-file <persist-file> or -R <persist-file>
	   Set the path and name of the syslog-ng.persist file where the
	   persistent options and data are stored.

       --pidfile <pidfile> or -p <pidfile>
	   Set path to the PID file where the pid of the main process is
	   stored.

       --process-mode <pidfile>
	   Sets how to run syslog-ng: in the foreground (mainly used for
	   debugging), in the background as a daemon, or in safe-background
	   mode. By default, syslog-ng runs in safe-background mode. This mode
	   creates a supervisor process called supervising syslog-ng , that
	   restarts syslog-ng if it crashes.

       --qdisk-dir <path> or -Q <path>
	   Specify the location of the file used for disk-based buffering. By
	   default, this file is located at /var/lib/syslog-ng/.

       --stderr or -e
	   Log internal messages of syslog-ng to stderr. Mainly used for
	   debugging purposes in conjunction with the --foreground option. If
	   not specified, syslog-ng will log such messages to its internal
	   source.

       --syntax-only or -s
	   Verify that the configuration file is syntactically correct and
	   exit.

       --user <user> or -u <user>
	   Switch to the specified user after initializing the configuration
	   file (and optionally chrooting). Note that it is not possible to
	   reload the syslog-ng configuration if the specified user has no
	   privilege to create the /dev/log file.

       --verbose or -v
	   Enable verbose logging used to troubleshoot syslog-ng.

       --version or -V
	   Display version number and compilation information.

FILES
       /etc/syslog-ng/syslog-ng.conf
