Logging to the System Log Daemon

ErrorLog syslog ErrorLog syslog:local7

On Unix systems, specify syslog as the argument to ErrorLog to instruct Apache to use the system log daemon to log Apache errors. This is shown in the example. You can optionally attach a facility (by default local7) as shown. A syslog facility is an information field that is associated with a syslog message to indicate the source of a log message. Facilities local0 to local10 are reserved for use by administrators and applications, such as Apache.
