seastar::memory::allocation_site Struct Reference

Detailed Description

Describes an allocation location in the code.

The location is identified by its backtrace. One allocation_site can represent many allocations at the same location. count and size represent the cumulative sum of all allocations at the location. Note the size represents an extrapolated size and not the sampled one, i.e.: when looking at the total size of all allocation sites it will approximate the total memory usage

#include <seastar/core/memory.hh>
