The SAP Host Agent is a tool used to perform several administration tasks in SAP systems. It is installed by default on all hosts.
The SAP HANA database lifecycle manager (HDBLCM) and the SAP HANA cockpit for offline administration rely on the SAP Host Agent to execute tasks as the system administrator user <sid>adm.
To audit operations performed in these SAP HANA tools, you must enable the audit logging feature of the SAP Host Agent. For more information about how to do this, see the SAP Host Agent documentation.
