Which system views would you use to monitor memory usage in HANA?

The choice of using M_MEMORY_USAGE and M_HOST_RESOURCE_UTILIZATION to monitor memory usage in HANA is particularly effective because these system views provide specific metrics essential for understanding memory consumption and overall resource utilization.

M_MEMORY_USAGE offers insightful details on the amount of memory being used by different components of the HANA database, helping DBAs to assess how memory is allocated and utilized by various operations. This information is crucial for identifying areas where memory usage may need to be optimized or monitored more closely.

Meanwhile, M_HOST_RESOURCE_UTILIZATION delivers a broader overview of the overall resource usage on the host system, including memory, CPU, and disk metrics. By using this view, you can gain valuable contextual information about how memory usage relates to other system resources, allowing for a comprehensive assessment of performance and potential bottlenecks.

Together, these views equip database administrators with the necessary tools to monitor, analyze, and optimize the memory usage of the HANA system effectively.
