Apache Error Log Format

everything that happens on your server, from the initial request, through the URL mapping process, to the final resolution of the connection, including any errors that may have occurred in the 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 apache access log format response time 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. Error Log Related ModulesRelated DirectivescoreErrorLogErrorLogFormatLogLevel The server error log, whose name and location is set by the ErrorLog directive, is the most important log file. This is the place where Apache httpd will send diagnostic information and record any errors that it encounters in processing requests.

Apache stores two kinds of logs: Access Log Contains information about requests coming in to the web server. This information can include what https://httpd.apache.org/docs/2.4/logs.html pages people are viewing, the success status of requests, and how long the request took to respond. It looks something like this: Apache 10.185.248.71 - - [09/Jan/2015:19:12:06 +0000] 808840 "GET /inventoryService/inventory/purchaseItem?userId=20253471&itemId=23434300 HTTP/1.1" 500 17 "-" "Apache-HttpClient/4.2.6 (java 1.5)" 1 10.185.248.71 - - [09/Jan/2015:19:12:06 +0000] 808840 "GET /inventoryService/inventory/purchaseItem?userId=20253471&itemId=23434300 HTTP/1.1" https://www.loggly.com/ultimate-guide/apache-logging-basics/ 500 17 "-" "Apache-HttpClient/4.2.6 (java 1.5)" Error Log Contains information about errors that the web server encountered when processing requests, such as when files are missing. It looks something like this: [Thu Mar 13 19:04:13 2014] [error] [client 50.0.134.125] File does not exist: /var/www/favicon.ico 1 [Thu Mar 13 19:04:13 2014] [error] [client 50.0.134.125] File does not exist: /var/www/favicon.ico Location Access and error log files are stored on individual web servers. The exact location of your Apache logs depends on your operating system: Debian/Ubuntu/Linux Mint Redhat/Fedora/CentOS Configuration OpenSUSE The following general default logging configuration directives are specified in absence of specific virtual host container configuration.

Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace. I replaced loglevel on apache config file: LogLevel debug After restarting, I'm getting the same error message without what could be called "a backtrace". As I understand apache access log there should be those 10 lines of redirects generated by mod_rewrite regex. After searching all over the internet I've found plenty of explanations of loglevel and mod_rewrite, but not a word of how to make loglevel debug work. Any ideas? debugging apache2 error-logging share|improve this question edited Jan 21 '13 at 20:07 BryanH 3,39312141 asked Apr 12 '11 at 21:05 Tiger 133125 closed as off-topic by Andrew Cheong, Christopher Creutzig, Sebastian, Mureinik, CDub Nov 26 '13 at 0:51 This question appears to be off-topic.

that happen when some software runs. The software's developer adds logging calls to their code to indicate that certain events have occurred. An event is described by a descriptive message which can optionally contain variable data (i.e. data that is potentially different for each occurrence of the event). Events also have an importance which the developer ascribes to the event; the importance can also be called the level or severity. When to use logging¶ Logging provides a set of convenience functions for simple logging usage. These are debug(), info(), warning(), error() and critical(). To determine when to use logging, see the table below, which states, for each of a set of common tasks, the best tool to use for it. Task you want to perform The best tool for the task Display console output for ordinary usage of a command line script or program print() Report events that occur during normal operation of a program (e.g. for status monitoring or fault investigation) logging.info() (or logging.debug() for very detailed output for diagnostic purposes) Issue a warning regarding a particular runtime event warnings.warn() in library code if the issue is avoidable and the client application should be modified to eliminate the warning logging.warning() if there is nothing the client application can do about the situation, but the event should still be noted Report an error regarding a particular runtime event Raise an exception Report suppression of an error without raising an exception (e.g. error handler in a long-running server process) logging.error(), logging.exception() or logging.critical() as appropriate for the specific error and application domain The lo
