SAP HANA MDC Monitoring Tool
Overview
ManageEngine Applications Manager provides comprehensive monitoring support for SAP HANA MDC (Multitenant Database Containers) database servers, enabling users to gain deep visibility into the performance and availability of both the system database and tenant databases. With this monitor, you can track key performance metrics such as memory usage, CPU utilization, connection statistics, expensive statements, disk usage, and data backup details. You can also configure threshold-based alerts and generate insightful reports to support proactive database management. Monitoring SAP HANA MDC with Applications Manager ensures optimal performance and helps in making informed capacity planning decisions.
