Controlling the Amount of Information Logged

LogLevel notice

The error information provided by Apache can be categorized according to degrees of importance. Use the LogLevel directive, supplying one of the arguments shown in Table 2.1, to choose the messages that you want to receive. Only errors of that level of importance or higher will be logged.

Table 2.1. LogLevel Options As Described in the Apache Documentation

Setting	Description	Example
emerg	Emergenciessystem is unusable	Child cannot open lock file. Exiting.
alert	Action must be taken immediately	getpwuid: couldn't determine user name from uid.
crit	Critical conditions	socket: Failed to get a socket, exiting child.
error	Error conditions	Premature end of script headers.
warn	Warning conditions	Child process 1234 did not exit, sending another SIGHUP.
notice	Normal but significant condition	httpd: caught SIGBUS, attempting to dump core in...
info	Informational	Server seems busy, (You may need to increase StartServers, or Min/MaxSpareServers)...
debug	Debug-level messages	Opening config file...

The default error level of "warn" is appropriate for most Apache installations. If you are trying to troubleshoot a specific configuration, however, you can lower the level all the way to "debug" to get much more detailed logging information.
