How to Use Categories 

Since most customers are operating many systems, the administrative personnel has no need to understand the inner structure of the software systems they are operating.

Log messages belonging to the same type of tasks are available in one and the same category. That is, messages are written from different software components into the same category if they belong to the same group of tasks, respectively the same main entity.

You can find the log categories in the following directory: <SAP_install_dir>/<system_name>/<instance_name>/j2ee/cluster/server<number>/log.

Category names are arranged hierarchically to reflect tasks and subtasks belonging together. Subcategories normally inherit properties of the parent category.

Bare in mind, that categories are created by default from the SAP Logging API. You cannot create your own categories.

Currently the following top-level categories are available:

●      Archive

This category contains the archived log files.

●      Services

This category contains messages related to services tasks.

●      System

This category contains messages related to system operation tasks. It has the subcategories Httpaccess, ConfigChanges, Database, Logging, Security, Security_Audit, Server andUserinterface to reflect the main entities.

●      Applications

This category contains messages related to application operation tasks.
