title: Amount used heap looking at gcmv in eclipse?
body: <p>It is not clear to me how much memory my app is actually needs when I use Garbage Collection and Memory Visualizer in Eclipse. Looking at this graph:
  <a href="https://i.stack.imgur.com/pB8pv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pB8pv.png" alt="gcmv view"></a></p>
  
  <p>At say 0:12 it has acquired a bit more than 0,4 GB. I know it acquires more heap (heap size in graph) than actually needs. But what I want to see is how much memory it really uses. The other two graphs just confuses the picture. Can I do that in gcmv?</p>
