Aug 19, 2013 199k views Apache Logging Server Optimization Ubuntu Introduction The Apache web server can be configured to give the server administrator important information about how it is functioning and what issues, if any, need to be addressed. The main avenue for providing feedback to the administrator is through the use of log files. ubuntu apache2 error log file location 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 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.

Apache Custom Log Format
Configure Web Logs in Apache By Blane Warrene February 23, 2004 One of the many pieces of apache error log format the Website puzzle is Web logs. Traffic analysis is central to most Websites, and the key to getting the most out of your traffic analysis revolves around how you https://www.digitalocean.com/community/tutorials/how-to-configure-logging-and-log-rotation-in-apache-on-an-ubuntu-vps configure your Web logs. Apache is one of the most -- if not the most -- powerful open source solutions for Website operations. You will find that Apache's Web logging features are flexible for the single Website or for managing numerous domains requiring Web log analysis. Author's Note: While most of this piece discusses configuration options for any https://www.sitepoint.com/configuring-web-logs-apache/ operating system Apache supports, some of the content will be Unix/Linux (*nix) specific, which now includes Macintosh OS X and its underlying Unix kernel. For the single site, Apache is pretty much configured for logging in the default install. The initial httpd.conf file (found in /etc/httpd/conf/httpd.conf in most cases) should have a section on logs that looks similar to this (Apache 2.0.x), with descriptive comments for each item. Your default logs folder will be found in /etc/httpd/logs. This location can be changed when dealing with multiple Websites, as we'll see later. For now, let's review this section of log configuration. ErrorLog logs/error_log

See the docs for details. Set the value according to your needs, and run service httpd restart to apply. There is no way to make Apache httpd change its verbosity while it's running, unfortunately. Some modules (like mod_php, mod_log_forensics, mod_security) though have their own way of increasing their logs' detail level, please see the module's docs for those - some of those may allow increasing verbosity without restarting httpd (e.g. mod_php using php.ini for PHP errors). With Apache httpd some of those (like mod_rewrite) directives were incorporated into the Loglevel directive and thus need httpd to be restarted. Inspecting Apache's settings If you want to know which directive has which value in a running apache instance, have a look at mod_info. On RHEL, its output at http://host/server-info (you have to enab
