Logging in the ICM
Use
The access log contains a log of accesses to the ICM from an intranet or the Internet, and thus gives you an overview of the activity on the ICM.
You can use external analysis programs to analyze the log file.
A HTTP subhandler implements logging in the ICM. This subhandler statistically analyzes HTTP requests and records requests.
The log handler uses the log file to serialize itself, which makes it a bottleneck. It is therefore not usually activated.
The logging implementation procedure corresponds to the Apache Web Server mod_log_config module.
Procedure
You configure logging using the parameter
icm/HTTP/logging_<xx>.
Sample Log Entries for Default Format (CLF):
10.18.103.34 - - [08/Jan/2001:16:53:20 +0100] "GET /sap/bc/bsp/sap/it00/default.htm HTTP/1.0" 200 336
10.18.103.34 - - [08/Jan/2001:17:01:15 +0100] "POST /bc/bsp/sap/it00/transition_parameter.htm HTTP/1.0" 302 0
The following string creates the CLF format:
%h %l %u %t "r" %s %bSample Log Entry for a Self-Defined Format
The following format
LOGFORMAT=%b %h %H %S %a %l %u %t %T Line=%r %f %U %s %{user-agent}i
gives these kind of entries:
