Which schema provides performance data and system alert details in SAP HANA MiniChecks?

The schema that provides performance data and system alert details in SAP HANA MiniChecks is _SYS_STATISTICS. This schema is designed specifically to track performance metrics and system behavior, offering insights into the operational status of the HANA system.

The performance data captured in _SYS_STATISTICS can include various aspects such as memory usage, processing times, and resource consumption, which are critical for monitoring the efficiency and health of the system. This data helps administrators to quickly identify potential issues and optimize performance as necessary.

In contrast, while other schemas might contain relevant information, they do not specifically focus on the comprehensive monitoring and alerting capabilities associated with system performance and alerts in the same manner as _SYS_STATISTICS does. Thus, it holds a unique position when it comes to performance data and is essential for effective system management in SAP HANA.
