You can use the tool hdbcons on operating system level for that purpose. Typical commands are:
|mm bl -rt <allocator>||mm bl -rt Pool/Statistics|| |
Show top components in <allocator> sorted by used size descending
|help mm||Overview of all memory management (mm) related command options|
mm bl -rt Pool/RowEngine/MonitorView
This output indicates that more than 100 GB of allocator Pool/RowEngine/MonitorView is consumed by the ExpensiveStatementsMonitor and so optimizations like adjustments to the expensive statements trace or implementing a bugfix to resolve a memory leak problem can be considered.
