In addition to this, third-party modules may ubuntu apache2 error log file location 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.

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.

The main avenue for providing feedback to the administrator is through the use of log files. Apache has a very configurable logging mechanism that can be used to output messages to different places based on instructions. In this guide, we will look at how to utilize Apache's logging functionality to set up structured, easy-to-parse logs. We will be using a default Apache2 installation on an Ubuntu 12.04 apache2 error log VPS. Other distributions should operate in a similar fashion. Apache Log Levels Apache separates all informational messages into categories depending on how important it considers the information. For instance, for the most important messages, considered emergencies, Apache designates the log level as "emerg". The "info" tag, on the other hand, just shows helpful information that can be useful to look at occasionally. Here are the log levels that Apache recognizes, from most important to least: emerg: Emergency situations where the system is in an unusable state. alert: Severe situation where action is needed promptly. crit: Important problems that need to be addressed. error: An Error has occurred. Something was unsuccessful. warn: Something out of the ordinary happened, but not a cause for concern. notice: Something normal, but worth noting has happened. info: An informational message that might be nice to know. debug: Debugging information that can be useful to pinpoint where a problem is occurring. trace[1-8]: Tracing information of various levels of verbosity that produces a large amount of information. When you specify a log level, you are not choosing to log the messages labeled in that category, you are choosing the least important level that you wish to log. This means that any levels above the selected level are also logged.

It would list .htaccess if it were possible. You may have a better chance at redirecting output through the server-side technology. But the best thing to do would be to contact your host. Access to your error log should be allowed. share|improve this answer answered Dec 21 '12 at 16:52 Jason McCreary 46.3k1280128 Thanks, I've contacted the support and the problem was solved. –fonini Dec 21 '12 at 18:39 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
