syslog-ng[-dFsvV] [-f<config-filename>] [-p<pid-filename>] [-C <chroot-dir>] [-u <user>] [-g <group>]
DESCRIPTION
syslog-ng reads and logs messages to the system console, log files,other machines and/or users as specified by its configuration file.
The configuration file is read at startup and is reread after receiptof a hangup (HUP) signal. When reloading the configuration file, alldestination files are closed and reopened as appropriate. For more information about the configuration file, see syslog-ng.conf(5).
Typically messages are sent to syslog-ng via a Unix domain socket(/dev/log) or via UDP, to port 514 or to whatever syslog/udpis defined to be in /etc/services. To receieve messages from thekernel, /dev/klog is opened for reading.
Messages sent to syslog-ng should be an entire line, prefixed by apriority code in between '<' and '>'. Definititions of the recognisedvalues can be found in the include file <sys/syslog.h>.
syslog-ng can be configured to pass messages on to other syslog-ng'sand when doing so, it sends the message on with the priority as a prefix.
It is not necessary to terminate a message with a line feed or carriage return.
