like to prepend the vhost name in my ErrorLog and then pipe it into a program I wrote. Is it possible to write Custom Error log format as it is with Access log? logging httpd apache-2.2 errors share|improve this question edited May 6 '11 at 16:37 Hangin on in quiet desperation 88k9113199 asked May 6 '11 at 15:35 JohnT 55113 Depending on your setup, you can have an ErrorLog for each of your virtual hosts. It's not ubuntu apache2 error log file location the same as a unified parsable logfile, but it's something. –muffinista May 6 '11 at 16:31 add a comment| 4 Answers 4 active oldest votes up vote 7 down vote For piping see the ErrorLog directive and Piped Logs official manual entries which explain it pretty well. 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. Apache 2.4 adds this support. See http://httpd.apache.org/docs/2.4/logs.html#errorlog. share|improve this answer edited Sep 17 '12 at 14:35 Community♦ 1 answered Sep 13 '12 at 13:59 Yishai 6111 add a comment| up vote 4 down vote With Apache 2.4 you can use the ErrorLogFormat directive. Syntax: ErrorLogFormat [connection|request] format Simple example ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M" Example (default format for threaded MPMs) ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i" Example (similar to the 2.2.x format) ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a] %M%

Apache Error Log Format
logs: Access Log Contains information about requests coming in to the web server. This information can include what pages people customlog 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 http://serverfault.com/questions/267036/is-it-possible-to-create-custom-error-log-in-apache-2 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" 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.

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. Log Level Directive This specifies log message severity. Default is “warn.” LogLevel warn Table of Level Severities Severity Description Example emerg Emergencies — system is unusable “Child cannot open lock file. Exiting” alert Immediate action required “getpwuid: couldn’t determine user name from uid” crit Critical conditions “socket: Failed to get a socket, exiting child” error Error conditions “Premature end of script headers” warn Warning conditions “child process 1234 did not exit, sending another SIGHUP” notice Normal but significant condition “httpd: caught SIGBUS, attempting to dump core in …” info Informational “Server seems busy…” debug Debug-level messages “opening config file …” trace1-8 Trace messages “proxy: FTP: … ” Note regarding a particular level: Levels are listed in order of descending severity. When triggered, a configured log level will log all events of that level or greater.

Logs are typically under /var/log, but some systems have them elsewhere. –Gilles May 19 '12 at 12:51 add a comment| 3 Answers 3 active oldest votes up vote 91 down vote accepted Ultimately, this depends on your Apache configuration. Look for CustomLog directives in your Apache configuration, see the manual for examples. A typical location for all log files is /var/log and subdirectories. Try /var/log/apache/access.log or /var/log/apache2/access.log. If the logs aren't there, try running locate access.log. share|improve this answer answered May 19 '12 at 12:54 Gilles 368k666671117 +1 for CustomLog –Radu 7 hours ago add a comment| up vote 20 down vote If you can't find the log with Gilles's answer, there are a couple more things you can try. Look in /var/log/httpd. Run sudo locate access.log as well as sudo locate access_log. The logs on my system were not visible except to root, and the file was called access_log instead of access.log. share|improve this answer answered Jan 27 '15 at 19:28 Don Kirkby 30124 3 +1 for /var/log/httpd - led me right to it on our CentOS installation –Chuck Wilbur Oct 2 '15 at 19:27 add a comment| up vote 5 down vote Apache server records all incoming requests and all requests processed to a
