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 Directives ErrorLog LogLevel The server error log, whose name and apache error log ubuntu 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. It is the first place to look when a problem occurs with starting the server or with the operation of the server, since it will often contain details of what went wrong and how to fix it. The error log is usually written to a file (typically error_log on unix systems and error.log on Windows and OS/2). On unix systems it is also possible to have the server send errors to syslog or pipe them to a program. The format of the error log is relatively free-form and descriptive. But there is certain information that is contained in most error log entries. For example, here is a typical message. [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1] client denied by server configuration: /export/home/live/ap/htdocs/test The first item in the log entry is the date and time of the message. The second entry lists the severity of the error being reported. The LogLevel directive is used to control the types of errors that are sent to the error log by r

Jdk14Logger, Log4JLogger, LogKitLogger, NoOpLog, SimpleLog public interface Log apache2 error log A simple logging interface abstracting logging APIs. In order to be instantiated apache errorlog successfully by LogFactory, classes that implement this interface must have a constructor that takes a single String parameter representing https://httpd.apache.org/docs/1.3/logs.html the "name" of this Log. The six logging levels used by Log are (in order): trace (the least serious) debug info warn error fatal (the most serious) The mapping of these log levels to the concepts used by the underlying https://commons.apache.org/logging/apidocs/org/apache/commons/logging/Log.html logging system is implementation dependent. The implementation should ensure, though, that this ordering behaves as expected. Performance is often a logging concern. By examining the appropriate property, a component can avoid expensive operations (producing information to be logged). For example, if (log.isDebugEnabled()) { ... do something expensive ... log.debug(theResult); } Configuration of the underlying logging system will generally be done external to the Logging APIs, through whatever mechanism is supported by that system.

If you're experiencing web server difficulties, or you just want to see what Apache is doing, log files should be your first stop. Apache records information about all visitors to your site, as well as any problems the server encounters. To do this, Apache uses two types of log files: apache error log access logs and error logs. Shared hosting accounts cannot view the raw Apache log files for the entire server. However, you can still view log file information for your own account. For information about how to view the access log for your account, please see this article. For information about how to view the error log for your account, please see this article.Table of Contents

Where is the Apache error log file located on [insert your Linux distro]? Error log and access log files are a useful piece of information for system admins, for example to troubleshoot their web server, protect it from various malicious activities, or just to run various analytics for HTTP server monitoring. Depending on your web server setup, its error/access logs may be found in different places on your system. This post may help you find Apache error log location on Linux. Apache Error Log Location on Debian, Ubuntu or Linux Mint Default Error Log On Debian-based Linux, the system-wide default location of Apache error log is /var/log/apache2/error.log. The default location can be customized by editing Apache configuration file. Custom Error Log To find a custom error log location, open /etc/apache2/apache2.conf with a text editor, and look for a line that starts with ErrorLog. This line specifies a custom location of Apache error log file. For example, the unmodified Apache configuration file has the following line: ErrorLog ${APACHE_LOG_DIR}/error.log In this case, the location is configured using APACHE_LOG_DIR environment variable, which is defined in /etc/apache2/envvars. export APACHE_LOG_DIR=/var/log/apache2$SUFFIX In reality, ErrorLog may point to any arbitrary path on your Linux system. Custom Error Log with VirtualHost If VirtualHost is used in Apache web server, ErrorLog directive can be specified within VirtualHost container, in which case the system-wide error log location described above will be ignored. With VirtualHost enabled, each VirtualHost can define its own custom error log location. To find out the error log location of a particular VirtualHost, you can open /etc/apache2/sites-enabled/
