Logging in the ICM and Web DispatcherLocate 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.

More information: Processing HTTP 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.


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

Parts of the URL


URI parameters in round brackets if they contain the context ID



Header fields (case insensitive)



SAP-R3Auth (RFC logon via HTTP)

Proxy authorization

MYSAPSSO2 (inheritance of the identity via HTTP channel)

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


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

  • 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)
