Extended Log Format
The extended log file combines the functions of the access log and the error log files, recording
information concerning requests and errors. This format places errors in context with the relevant
request.
If –remotePort is used then the entries in the access log file as follows:
150.180.13.54 - - [24/Jan/1995:12:27:13 -0500] "GET /dirsite.gif HTTP/1.0" 200 7114 2168 quinton.jax.org - -
[24/Jan/1995:12:27:14 -0500] "GET / HTTP/1.0" 200 1280 6935 tucano.cv.com - - [24/Jan/1995:12:27:16 -0500] "POST
/dir/search.cgi HTTP/1.0" 200 15691 6985
If CombinedLogFormat is set to On and –cookie option is also used, the format for log entries is
as follows:
150.180.13.54 - - [24/Jan/1995:12:27:13 -0500] "GET /dirsite.gif HTTP/1.0" 200 7114 "http://www.abc.com/"
"Mozilla/4.05 [en] (WinNT; I)" "USERID=CustomerA; IMPID=01234"
Extended Log Entry Format
An entry in the extended log file consists of a single line of ASCII text. Each entry consists of the
tag log followed by one or more items composed of an item-name and an item-value:
log {item-name1 item-value1} {item-name2 item-value2} ...
Table C-2 lists the items that might appear in an extended log entry.
