6.2.2 HTTP Server Log Records


The record shown in Figure 6-3 is used by the CA MICS Web
Analyzer Option.  The figure shows when the record is 
written and what each record contains.

HTTP Server Log records are generated by the HTTP Web Server.
The server records activity in various log files each time a
web page is accessed.  This makes the data in log files event
driven.  The Web Server can be configured to log many
different types of activities.  A maximum of eight log files
can be activated and generated.  Each night at midnight the
server closes the current logs and creates new logs for the
new day.  Following is a list of the log files:

Server Access Log  Contains an activity of requests made to 
                   the server.

FRCA Access Log    Contains activity of requests served by 
                   the Fast Response Cache Accelerator 
                   (FRCA).

Proxy Access Log   Contains activity of requests processed 
                   by the proxy server.

FRCA Proxy Log     Contains activity of requests processed 
                   by the proxy server's cache.

Agent Log          Contains the browser name used to access 
                   the requested resource.

Referer Log        Identifies the web page that referred 
                   (linked to) the requested resource.

Error Log          Contains errors encountered by the 
                   server's client.

CGI Error Log      Contains standard error output (stderr) 
                   from CGI programs.

The CA MICS Web Analyzer Option provides a WEB Log Extractor 
(WLE) utility to preprocess and reformat the log files.  As 
many as seven log files from each server are accepted for 
processing in the DAY052 step.

The Web Log Extractor (WLE) utility uses its config file to
determine the specific log files for specified servers to
process and reformat.  You must specify each server and the
path name for its log files.  The log files and their
corresponding SMF-like records generated by the WLE utility
are shown in Figure 6-3.

NOTE:  The data will be logged to the Proxy logs (access and
       cache) or the FRCA and Server Access logs, never to
       both.
