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
Apache Loglevel
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. 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 la
Apache Server kann so konfiguriert werden, dass der komplette "Arbeitsablauf" aufgezeichnet wird. Wo diese Log Dateien gespeichert sind und was sie enthalten können, wird hier apache error log format beschreiben. CustomLog Die Log-Datei die in der Direktive CustomLog angegeben apache log level debug wird, protokolliert den Zugriff auf den Apache Webserver. Welche Daten dabei in der CustomLog

#DieVoreinstellungsiehtsoaus:CustomLoglogs/access_logcommon#LinuxCustomLoglogs/access.logcommon#Windows Dabei wird mit logs/access.log angegeben wo die Datei liegt und common sagt aus welches LogFormat verwendet https://www.digitalocean.com/community/tutorials/how-to-configure-logging-and-log-rotation-in-apache-on-an-ubuntu-vps wird. Die Logdatei kann aber auch mit einer Pipe (Senkrechtstrich |) an ein Programm weitergereicht werden um eine automatische Auswertung der Logdatei zu generieren oder aber auch um Log Dateien die sehr groß sind auszutauschen, etwa mit dem mitgelieferten Programm Rotatelogs. CustomLog"|bin/rotatelogs.exeaccess.log86400"common#WindowsCustomLog"|bin/rotatelogsaccess_log86400"common#Linux Dies hat den Vorteil, dass der Apache http://www.a-coding-project.de/ratgeber/apache/server-logging-und-status nicht dauerhaft auf die Logdatei zugreift und diese zwischendurch auch geleert oder einfacher ausgewertet werden können. LogFormat Das LogFormat definiert wie die CustomLog Datei aussieht. Standardmäßig sind bereits 4 Formate definiert die benutzt werden können. LogFormat"%h%l%u%t"%r"%>s%b"%{Referer}i""%{User-Agent}i""combined#HINWEIS:AllesineinerZeile LogFormat"%h%l%u%t"%r"%>s%b"commonLogFormat"%{Referer}i->%U"refererLogFormat"%{User-agent}i"agent Natürlich können auch eigene Formate definiert werden. Dazu muss nur eine weitere LogFormat Direktive geschrieben und Ihr ein eindeutiger Name zugeordnet werden. Anschließend das Format noch der CustomLog-Direktive zugewiesen und schon gibt es die gewünschten Daten in der Log Datei. LogFormat"%h"%r""meinFormatCustomLoglogs/access.logmeinFormat Innerhalb des Formats können mehrere Platzhalter für die jeweiligen Daten eingesetzt werden. Hier die wichtigsten:." - "t - Tabulator n - neue Zeile%h - IP Adresse des Clients%i - Ident Lookup%u - Username bei HTTP-Authentifizierung z.B. über .htacces%t - Ende der Bearbeitungszeit des Servers%r - Clientbefehl GET etc. inkl.

Logs are written in a https://xvm.scripts.mit.edu/browser/trunk/packages/sipb-xen-www/files/etc/apache2/sites-available/ssl?rev=526 customizable format, and may be written directly to a file, or to an external program. Conditional logging is provided so that individual requests may be included or excluded from the logs based on characteristics of the request. Three directives are provided by apache log this module: TransferLog to create a log file, LogFormat to set a custom format, and CustomLog to define a log file and format in one step. The TransferLog and CustomLog directives can be used multiple times in each server to cause each request to be logged to multiple files. apache access log Directives BufferedLogs CustomLog LogFormat TransferLog Topics Custom Log Formats Security Considerations See also Apache Log Files Comments Custom Log Formats The format argument to the LogFormat and CustomLog directives is a string. This string is used to log each request to the log file. It can contain literal characters copied into the log files and the C-style control characters "\n" and "\t" to represent new-lines and tabs. Literal quotes and backslashes should be escaped with backslashes. The characteristics of the request itself are logged by placing "%" directives in the format string, which are replaced in the log file by the values as follows: FormatString Description %% The percent sign. %a Client IP address and port of the request. %{c}a Underlying peer IP address and port of the connection (see the mod_remoteip module). %A Local IP-address. %B Size of response in bytes, excluding HTTP headers. %b Size of response in bytes, e
