Apparently there's not a damn thing I can do about it:
http://httpd.apache.org/docs/2.0/logs.html
"The first item in the log entry is the date and time of the
message. The second entry lists the severity of the error being
reported. The LogLevel directive is used to control the types of
errors that are sent to the error log by restricting the
severity level. The third entry gives the IP address of the
client that generated the error. ... It is not possible to
customize the error log by adding or removing information."
WHY WHY WHY?
This works well for me as an error log pipe, at least while I'm
developing.
#!/usr/bin/perl
use strict;
use warnings;
open LAME, '>>', '/var/log/apache2/lame.log';
select LAME;
$| = 1;
while (<STDIN>) {
s{ \A \[.*?\] \s* \[.*?\] \s* \[.*?\] }{}xms;
s{ , \s referer: \s http:// .*? \z }{}xms;
print LAME $_;
}
