Citrix Systems CITRIX NETSCALER 9.3 Benutzerhandbuch

%r

The first line of the request.

%s

For requests that were redirected
internally, this is the status of the
original request.

%t

The time, in common log format
(standard English time format).

%{format}t

The time, in the form given by format,
must be in the strftime(3) format. For
format descriptions, see 

 on page 121.

%T

The time taken to serve the request, in
seconds.

%u

The remote user (from auth; may be
bogus if return status (%s) is 401).

%U

The URL path requested.

%v

The canonical name of the server serving
the request.

%V

This is the virtual server IPv4 address in
the system, if load balancing, content
switching, and/or cache redirection is
used.

%V6

This is the virtual server IPv6 address in
the system, if load balancing, content
switching, and/or cache redirection is
used.

For example, if you define the log format as %+{user-agent}i, and if the user agent
value is Citrix NetScaler system Web Client, then the information is logged as Citrix
NetScaler system +Web+Client. An alternative is to use double quotation marks. For
example, “%{user-agent}i” logs it as “Citrix NetScaler system Web Client.” Do not use
the <Esc> key on strings from %.. .r, %. . .i and, %. . .o. This complies with the
requirements of the Common Log Format. Note that clients can insert control
characters into the log. Therefore, you should take care when working with raw log files.
