Configuring the syslogd messaging facility

Through the syslogd messaging facility, you can send event messages to a finite list of facilities.

The syslogd daemon is a system logging utility that is a transport mechanism for sending event messages. It supports a finite list of facilities that is not extendable (at least not on all platforms). All SafeLinx Server components use the user facility when they generate messages for syslogd.
Note: syslogd is not supported on Windows.

To configure the syslogd to write all user-friendly facility messages to a specific log file, add this line to the /etc/syslogd.conf file:


The priority facility can also be refined to send high priority to a different file from all other messages. The syslogd priorities can be mapped to SafeLinx Server log levels.
SafeLinx Server log level Syslogd priorities Description
error err Messages about unexpected events on which you must take action
warn warning Messages about events on which you may or may not need to take action
log info General information messages
trcart info Hexadecimal dump of data packets
trcip info Hexadecimal dump of only IP-related data packets
status info Dump of status information, such as packet rates, byte rates, and system load
tcp-lite info Messages about data using the TCP-Lite transport
debug debug Data used for problem analysis

The following examples make use of priority to log messages to different files.

user.err;user.warn /tmp/cmlog.err /tmp/cmlog.log

When changes are made to the syslog.conf file, the syslogd must be refreshed or restarted.

Before you refresh or restart the syslogd daemon, make sure that the files that you are using to log messages exist on the file system.

There are several other options for configuring options such as the maximum log file sizes, time/date format, or sending logs to a remote server. Consult your operating system documentation for this specific information.
