syslog-ng - syslog-ng system logger application
syslog−ng [options] |
NOTE: This manual page covers both editions of syslog−ng: syslog−ng Open Source Edition and the commercial syslog−ng Premium Edition. Features that are only included in the Premium Edition are marked with an asterisk (*). For details, see the official syslog−ng website: http://www.balabit.com/network−security/syslog−ng/.
This manual
page is only an abstract; for the complete documentation of
syslog−ng, see
The syslog−ng Administrator Guide [1].
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.
−−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, when syslog−ng restarts itself if it crashes. By default, syslog−ng runs in safe−background mode.
−−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.
−−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.
