ErrorLog

Synopsis

ErrorLog filename|syslog[:facility] 
Default: ErrorLog logs/error_log
Server config, virtual host

The ErrorLog directive sets the name of the file to which the server will log any errors it encounters. If the filename does not begin with a slash (/), it is assumed to be relative to the server root.

If the filename begins with a pipe (|), it is assumed to be a command to spawn a file to handle the error log.

Apache 1.3 and Above

Using syslog instead of a filename enables logging via syslogd(8) if the system supports it. The default is to use syslog facility local7, but you can override this by using the syslog: facility syntax, where facility can be one of the names usually documented in syslog(1). Using syslog allows you to keep logs for multiple servers in a centralized location, which can be very convenient in larger installations.

Your security could be compromised if the directory where log files are stored is writable by anyone other than the user who starts the server.
