Summary of tracked heap memory allocation data
Flamegraph visualization of number of heap memory allocations
Chart of heap memory allocations over time

Heaptrack traces all memory allocations and annotates these events with stack traces. Dedicated analysis tools then allow you to interpret the heap memory profile to:

  • find hotspots that need to be optimized to reduce the memory footprint of your application
  • find memory leaks, i.e. locations that allocate memory which is never deallocated
  • find allocation hotspots, i.e. code locations that trigger a lot of memory allocation calls
  • find temporary allocations, which are allocations that are directly followed by their deallocation
