Configuring Messaging Server Log SettingsLocate this document in the navigation structure

Messaging Server logs create trace configurations for messaging modules, and retrieve trace data for all or specific messages. Configure trace configuration properties for modules to specify the amount of detail that is written to the log. You can configure trace settings for the primary server cluster in SAP Control Center for each module. The settings are available to cluster servers through the shared data folder.


Note The default settings may only need to change in case of technical support situations where, for diagnostic reasons, a request is made to configure the specific module(s) settings, and provide the request log. In all other cases, the administrator or developer should not need to change the settings.

Additionally, you should always use SAP Control Center to configure server logs. If you manually edit the configuration file, especially on secondary servers in a cluster, the servers may not restart correctly once shut down.


  1. In the SAP Control Center left navigation pane, click Configuration.
  2. In the right administration pane, click the Log Setting tab and select Messaging Server.
  3. Select Default, or one or more of the messaging service modules. Click Show All to show all modules.
