Function documentation HTTP Logging Locate the document in its SAP Library structure



If you are using your SAP System as an HTTP client or server, you can record the HTTP requests.

You can then evaluate the resulting log file. 


The following components of the SAP System support HTTP logging:

        Internet Communication Manager (ICM). For details see Structure linkLogging in ICMs.

        SAP Message Server. The section below explains how to activate logging in the message server.

HTTP Logging in the Message Server

You activate logging in the parameter ms/http_logging(default = 0, no logging), by setting the value to 1. You can change the parameter value in transaction SMMS (Message Server Monitor) or RZ11. If you deactivate logging, the log file will not be closed - all the buffered data is written to the hard drive so that it is available in the file.

You can define the log format in parameter ms/HTTP/logging_0.

The syntax is the same as in Structure linkicm/HTTP/logging_<xx>, though only index 0 is supported.

The standard value is


whereby the format string for SAPMSG is:

%h %l %u %t "%r" %s %b %{location}o


Set the parameter as described above.


The content of a log file will look like: - - [01/Oct/2003:13:29:57+0200] "GET /msgserver/text/logon HTTP/1.1" 200 - ls3022 - - [01/Oct/2003:14:10:05+0200] "GET /sap/bc/ping HTTP/1.0" 301 - <http://binmain:8080/sap/bc/ping> - - [01/Oct/2003:14:11:15+0200] "GET /sap/bc/ping HTTP/1.0" 301 - <http://ls3022:8080/sap/bc/ping>
