Accesslog¶
Module: mod_accesslog
- Table of contents
- Accesslog
Description¶
CLF like by default, flexible like apache
Options¶
accesslog.use-syslog send the accesslog to syslog Default: disabled accesslog.filename name of the file where the accesslog should be written to if syslog is not used. if the name starts with a '|' the rest of the name is taken as the name of a process which will be spawned and will get the output e.g.: :: accesslog.filename = "/var/log/lighttpd.log" $HTTP["host"] == "mail.example.org" { accesslog.filename = "|/usr/bin/cronolog" } if you have multiple workers on 1.4.x (now, the current version) and want all access logs to be written (without that, only one worker will write logs), use the accesslog.filename = "\|/usr/sbin/cronolog.. (as a temporary solution) Default: disabled accesslog.format the format of the logfile ====== ================================ Option Description ====== ================================ %% a percent sign %h name or address of remote-host %l ident name (not supported) %u authenticated user %t timestamp for the request-start %r request-line %s status code %b bytes sent for the body %i HTTP-header field %a remote address %A local address %B same as %b %C cookie field (not supported) %D time used in ms (not supported) %e environment (not supported) %f physical filename %H request protocol (HTTP/1.0, ...) %m request method (GET, POST, ...) %n (not supported) %o `response header`_ %p server port %P (not supported) %q query string %T time used in seconds %U request URL %v server-name %V HTTP request host name %X connection status %I bytes incomming %O bytes outgoing ====== ================================ If %s is written %>s or %<s the < and the > are ignored. They are supported for compatibility with apache. %h will always return the IP address of the host, never the name. This makes it equivalent to %a, which is not implemented. %a, %A, %{name}C, %D and %e are all unimplemented as of 1.4.18 and 1.5.0-r1922 %i and %o expect the name of the field which should be written in curly brackets. %q is not prepended with '?', unlike Apache Unlike Apache, %{StrFTime format string}t is not supported. There is a patch here : http://redmine.lighttpd.net/issues/show/1479
In lighttpd version 1.3.16, the default format is:
accesslog.format = "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""Default: CLF compatible output.
In lighttpd versions 1.4.13-1.4.20, the default setting is:
accesslog.format = "%h %V %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""
The difference between Apache's CLF is the second field changes from ``%l`` to ``%V``.
Response Header¶
The accesslog module provides a special way to log content from the
application in a accesslog file. It can be used to log the session id into a
logfile.
If you want to log it into the accesslog just specify the field-name within
a %{...}o like ::
accesslog.format = "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" \"%{X-LIGHTTPD-SID}o\""
The prefix ``X-LIGHTTPD-`` is special as every response header starting with
this prefix is assumed to be special for lighttpd and won't be sent out
to the client.
An example the use this functionality is provided below: ::
<?php session_start(); header("X-LIGHTTPD-SID: ".session_id()); ?> TEST
----
Note: If you log to a pipe and have lighty chrooted the user running lighty will need access to “/bin/sh”.
