To be more precise we need to multiply it by page size with system overhead (systemPageSize). If we want to print only used offheap memory, this will solve the problem. If we want to print, for example, currently allocated (commited) offheap memory (if persistence is disabled for data region then offheap is allocated by chunks) we need to do more complex calculations and there is no public API for this now.
