I know jconsole and other strument for calcolate the sum Heap.
I usally i run kill -3 on the PID
[rhusar@rhusar as-master]$ jmap -histo:live 18281 | head
num #instances #bytes class name
----------------------------------------------
1: 176916 24493688 <constMethodKlass>
2: 176916 24077408 <methodKlass>
3: 22170 23879160 <constantPoolKlass>
4: 22170 18736416 <instanceKlassKlass>

6: 198198 12992576 [B
