SAP (xm_sap)

This module provides support for parsing the SAP Security Audit Log (SAL). It registers an InputType using the name of the module instance. This module can be used with the im_file input module.

To examine the supported platforms, see the list of installer packages in the Available Modules chapter.

Configuration

The xm_sap module accepts only the common module directives.

Examples

Example 1. Parsing SAP audit log

This example uses the im_file input module to read SAP Security Audit Log files and specifies the xm_sap instance name in the InputType directive. Log records are then converted to JSON using the to_json() procedure of the xm_json module.
