Detailed Description

Monitor memory allocations done by the middleware on the native heap.

RTI Connext allows you to monitor the memory allocations done by the middleware on the native heap. This feature can be used to analyze and debug unexpected memory growth.

After NDDSUtilityHeapMonitoring::enable is called, you may invoke NDDSUtilityHeapMonitoring::take_heap_snapshot to save the current heap memory usage to a file. By comparing two snapshots, you can tell if new memory has been allocated and, in many cases, where.
