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 of the request (see the mod_remoteip module). %{c}a Underlying peer IP address 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, excluding HTTP headers.

Apache stores two kinds of logs: Access Log Contains information about requests coming in to the web server. This http://httpd.apache.org/docs/current/mod/mod_log_config.html information can include what 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 - https://www.loggly.com/ultimate-guide/apache-logging-basics/ - [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.

Any idea? Note that what is on /etc/apache2/conf.d/other-vhosts-access-log is not a default option but a global option. 12.04 configuration apache2 logging share|improve this question edited Mar 4 '13 at 22:47 asked Mar 4 '13 at 22:39 gsi-frank 67151533 add a comment| 3 Answers 3 apache error log active oldest votes up vote 4 down vote accepted It is clearly stated in the documetation for the TransferLog statement: This directive has exactly the same arguments and effect as the CustomLog directive, with the exception that it does not allow the log format to be specified explicitly or for conditional logging of requests. Instead, the log format is determined by the most recently specified LogFormat directive which does not define a nickname. Common Log Format is used if no other format has been specified. Go on to the LogFormat statement: Default: LogFormat "%h %l %u %t \"%r\" %>s %b" So if a TransferLog statement is given without any LogFormat statement the output format is as described above. If also the TransferLog statment is missing no access log is written. share|improve this answer edited Mar 4 '13 at 23:20 answered Mar 4 '13 at 22:55 H.-Dirk Schmitt 3,1271420 Thanks, but still can't read anything about TransferLog default, I mean, are you saying that if no CustomLog is specified, the TransferLog directive is in charge even it is not specified? If that is the case, where do you read that? cos TransferLog hasn't a default section defined. Thanks again. –gsi-frank Mar 4 '13 at 23:13 If no TransferLog is defined, it is not written. –H.-Dirk Schmitt Mar 4 '13 at 23:21 add a comment
