Background documentationLogging in the ICM and Web Dispatcher Locate this document in the navigation structure


To get an overview of the load on the ICM and Web Dispatcher, an access log can be created in which accesses from the Intranet and Internet are logged. You can also log accesses to the Internet for the ICM (if the SAP NetWeaver Application Server acts as the client).

You can use external analysis programs to analyze the log file.

An HTTP subhandler implements logging in the ICM / Web Dispatcher. This subhandler statistically analyzes HTTP requests and records requests.

For more information, see: Processing HTTP Requests

Caution Caution

The log handler uses the log file to serialize itself, which makes it a bottleneck. It is therefore not usually activated.

End of the caution.

The logging implementation procedure corresponds to the Apache Web Server mod_log_config module.

Note Note

For security reasons the following information is hidden (replaced with points) from the logging procedure.

End of the note.

Example Example

An entry could look like: - - [25/May/2004:18:06:57 +0200] "GET /sap(..................)/public/icman/test;jsessionid=...../umu.html?sap-user=saphttp&sap-password=....&test=111 HTTP/1.1" 404 2144

End of the example.

You can configure logging in parameters icm/HTTP/logging_<xx> (for incoming requests) and icm/HTTP/logging_client_<xx> (for outgoing requests).

Example Example

  • Sample Log Entries for Default Format (CLF) - - [08/Jan/2009:16:53:20 +0100] "GET /sap/bc/bsp/sap/it00/default.htm HTTP/1.0" 200 336 - - [08/Jan/2009:17:01:15 +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 %b

  • Sample 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:

    181 8080 - - [11/Apr/2009:14:01:08 +0200] 0 Line=GET /sap/bc/bsp/sap/it00 HTTP/1.1 /bc/bsp/sap/it00 /bc/bsp/sap/it00 500 Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

End of the example.

You can display the logging data in the ICM Monitor (transaction SMICM) by choosing   Goto   HTTP Plug-In   Server Logs   or Client Logs. A list of all logs then appears, and you can display logs and associated information.
