Syslog

About

The Syslog module logs events by sending messages to the logging facility of your web server's operating system. Syslog is an operating system administrative logging tool that provides valuable information for use in system management and security auditing. Most suited to medium and large sites, Syslog provides filtering tools that allow messages to be routed by type and severity. For more information, see the online handbook entry for Syslog module and PHP's openlog and syslog functions.

Uses

Logging for UNIX, Linux, and Mac OS X

On UNIX, Linux, and Mac OS X, the file /etc/syslog.conf defines the routing configuration. Messages can be flagged with the codes LOG_LOCAL0 through LOG_LOCAL7. For information on Syslog facilities, severity levels, and how to set up syslog.conf, see the syslog.conf manual page on your command line.

Logging for Microsoft Windows

On Microsoft Windows, messages are always sent to the Event Log using the code LOG_USER.
