HTTP Access Logging Specifics When Using Solution Manager Diagnostics

As part of the setup of the  Solution Manager Diagnostics (SMD), you have to configure certain HTTP Provider service logging properties. As a result, the default HTTP access logging behavior is overridden in a particular case, which is described below.

For more information about the default HTTP access logging behavior, see Logging in Common Log File Format and Logging Additional Information .

For more information about the SMD setup, see SAP Service Marketplace at service.sap.com/nw04operation → Supportability.

The system distinguished if the special tracing for SMD purposes is needed based on an SAP-proprietary HTTP header named X-CorrelationID . If the value of the LogHeaderValue property of the HTTP Provider service is set to X-CorrelationID , then requests that contain an X-CorrelationID header are logged in the additional trace file smdresponses.<n>.trc. By default, the J2EE Engine uses the file system directory <J2EE_home>/cluster/server<N>/log/system/httpaccess for the location of this trace file.

All other HTTP requests are logged according to the default HTTP access logging behavior.
