NAME

syslogd - log system messages

SYNOPSIS

/usr/ucb/syslogd [ -d ] [ -fconfigfile ] [ -m interval ]

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(5)] controls where messages are forwarded. syslogd logs a mark (timestamp) message every interval 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, from any transport provider specified in /etc/netconfig, /etc/net/transport/hosts, and /etc/net/transport/services, and from the special device /dev/klog (for kernel messages). syslogd reads the configuration file when it starts up, and again whenever it receives a HUP signal, 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 ID (PID).

The following options are available:

-d Turn on debugging.

-fconfigfile Specify an alternate configuration file.

-m interval Specify an interval, in minutes, between mark messages.
