Name

syslogd - log system messages

Synopsis

/usr/sbin/syslogd [ -d ] [ -f configfile ] [ -m markinterval ] [ -p path ]

Availability

SUNWcsu

Description

syslogd reads and forwards system messages to the appropriate log files and/or users, depending upon the priority of a message and the system facility from which it originates. The configuration file /etc/syslog.conf (see syslog.conf(4) ) controls where messages are forwarded. syslogd logs a mark (timestamp) message every markinterval minutes (default 20) at priority LOG_INFO to the facility whose name is given as mark in the syslog.conf file.

A system message consists of a single line of text, which may be prefixed with a priority code number enclosed in angle-brackets (<>); priorities are defined in <sys/syslog.h>.

syslogd reads from the STREAMS log driver, /dev/log, and from any transport provider specified in /etc/netconfig, /etc/net/transport/hosts, and /etc/net/transport/services.

syslogd reads the configuration file when it starts up, and again whenever it receives a HUP signal (see signal(5) , at which time it also closes all files it has open, re-reads its configuration file, and then opens only the log files that are listed in that file. syslogd exits when it receives a TERM signal.

As it starts up, syslogd creates the file /etc/syslog.pid, if possible, containing its process identifier (PID ).
