Possible to see args/kwargs for individual function calls?

Does memray record the args/kwargs of individual function calls?

Basically I just need to be able to tell whether the memory leak was due to lots of small allocations, or one huge one -- and if so, find out what exactly caused that huge allocation.

No, Memray only records the stack at which each allocation was performed, it doesn't record anything about the local variables or function parameters. It does record the size of each allocation, so you can figure out whether the number of bytes allocated by a given function were spent all in one big allocation or in many small allocations. That's not surfaced well in the stats reporter (all you see is a total size and a count for each stack), but the stats reporter gives a histogram of allocation sizes, and the with memray transform csv you can write out a CSV file containing every allocation that was performed, the allocator used to perform it, the thread the allocation happened in, and the stack trace leading to the allocation.

Okay, thanks for the explanation. I'll have to check out the transform csv option, that sounds close to what I want.
