Hello,

Does anyone have any idea about how it would be possible to measure heap usage? For this
purpose, do we need to follow a statistical measurement approach?

Thanks

Hi,

A simple approach is to create a mutex object with all the necessary
statistics, modify its instant/cumulative value fields each time a local
allocation/free occurs and based on these, calculate extremas, averages
and other moments (whatever is needed) once per a time unit.

     STRUCTURE HEAP_USAGE_MUTEX
     begin
        Heap_Size                 ; increment on alloc/ decrement on free
        Min_Heap_Size             ; update on each free
        Max_Heap_Size             ; update on each alloc
        Cumulative_Alloc_Size     ; init to 0, increment on alloc
        Cumulative_Free_Size      ; init to 0, increment on free
        No_of_Allocs              ; init to 0, increment on alloc
        No_of_Frees               ; init to 0, increment on free
        ...                       ; etc.
     end

Rgds,
