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.

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. Currently the following top-level categories are available:

●      Applications

This category contains messages related to application operation tasks.

●      Archive

This category contains the archived log files.

●      System

This category contains messages related to system operation tasks. It has the subcategories HTTPAccess, Database, Network, Server and Security to reflect the main entities, respectively important groups of tasks.

●      Services

This category contains messages related to services tasks.

In general, categories must be chosen with care to be kept as consistent as possible.
