process. In addition to this, third-party modules may provide logging capabilities, or inject entries into the existing log files, and applications such as CGI programs, or PHP scripts, or other handlers, may send messages to the server error log. In this document we discuss the logging modules that are a standard part of the http server. Security Warning Anyone who can write to the directory where Apache httpd is writing a log file can almost certainly gain access to the uid that the server is started as, which is normally root. Do NOT give people write access to the directory the logs are stored in without being aware of the consequences; see the security tips document for details. In addition, log files may contain information supplied directly by the client, without escaping. Therefore, it is possible for malicious clients to insert control-characters in the log files, so care must be taken in dealing with raw logs.

It's not the same as a http://serverfault.com/questions/267036/is-it-possible-to-create-custom-error-log-in-apache-2 unified parsable logfile, but it's something. –muffinista May 6 '11 at 16:31 add a comment| 4 Answers 4 active oldest votes up vote 7 down vote For piping see the ErrorLog directive and Piped Logs official manual entries which explain it pretty well. Getting a custom error log format is more difficult. You can customize the access log easily with LogFormat but there is nothing built in for modifying the error log format. I did come across CGI::Carp which is a Perl module for outputting to the error log. Finally, there is always modifying the Apache source code directly depending on how badly you want this feature. share|improve this answer answered May 6 '11 at 16:27 uesp 2,9441911 add a comment| up vote 6 down vote In Apache 2.2 you cannot change the format of error_log easily - see http://httpd.apache.org/docs/2.2/logs.html#errorlog. Apache 2.4 adds this support.

Syntax: ErrorLogFormat [connection|request] format Simple example ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M" Example (default format for threaded MPMs) ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i" Example (similar to the 2.2.x format) ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i" Advanced example with req

Start Because of CustomLog Syntax Error in httpd.conf Solution - Apache / HTTP Failed to Start Because of CustomLog Syntax Error in httpd.conf By: Ravi, Categories: Apache,Dedicated Server,Tutorials,VPS, 0 comments I was recently working on a server with http://www.lophost.com/tutorials/solution-apache-http-failed-to-start-because-of-customlog-syntax-error-in-httpd-conf/ CentOS 6 installed and trying to configure Apache virtual hosts to host several domains / websites without any control panel like cPanel.

to security We'll discuss both of these, below. Sending our web logs to syslog We can send our weblogs to syslog by putting a pipe-to-command entry in our log messages for the webserver. We'll also save the logs like usual, so that we can run our logs processing commands, etc. This means we take entries like: ErrorLog "/var/log/www/error.log" CustomLog "/var/log/www/access.log" extended_ncsa (assuming our logs go in /var/log/www) and replace them with: ErrorLog "|/bin/sh -c '/usr/bin/tee -a /var/log/www/error.log | /usr/bin/logger -thttpd -plocal6.err'" CustomLog "|/bin/sh -c '/usr/bin/tee -a /var/log/www/access.log | /usr/bin/logger -thttpd -plocal6.notice'" extended_ncsa for apache 2.0.x or ErrorLog "|/usr/bin/tee -a /var/log/www/error.log | /usr/bin/logger -thttpd -plocal6.err" CustomLog "|/usr/bin/tee -a /var/log/www/access.log | /usr/bin/logger -thttpd -plocal6.notice" extended_ncsa for apache 2.2.x. This has us using Unix "tee" to write the log where it was being written, but also sends the entries to "logger" (which is the command line utility to send things to syslog). Log Format Some installations of Apache will not define the extended_ncsa log format. The result is that nothing will be logged by Apache. If this is the case for your installation, you can alternately use the format combined which is typically defined in default Apache installations. In the above example for apache 2.2.x, this would change your configuration entry for your access log, to look like the following CustomLog "|/usr/bin/tee -a /var/log/www/access.log | /usr/bin/logger -thttpd -plocal6.notice" combined Sending syslog data to CST The syslog config file needs to be modified to handle these messages appropriately. There are two changes you probalby want to make here: Don't log web messages to /var/adm/messages Send all syslog stuff to CST via clogger.fnal.gov This generally means editing your /etc/syslog.conf and changing # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none /var/log/messages to # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none;local6.none /var/log/messages # send anything remotely interesting to clogger #
