Memory on WebInterface differs from /spark health Command

[StaticFX]

Description

Hello,
using spark 1.10.42-forge i see the following issue. On the webinterface i get the info, that my server has 6,3GB of ram (process). I set the server to use 12GB of ram using the -Xmx12G flag. Using the /spark health command i also get this behaviour.

Reproduction Steps

• Set server Ram to 12G
• Open spark profiler using the command
• Compare memory values to /spark health

Expected Behaviour

Both memory values should be the same

Both numbers are "correct" in their way. As you noticed, the /spark health command shows a diagram of how large the heap currently is and how large it is allowed to get. What it doesn't show as your console doesn't show colors: One of the bars is colored differently, marking the committed heap space. As an example, see the red bar here:

This bar is what's shown as the upper (process) memory value in the web viewer. If you switch to the memory tab, you can also see this in more detail:

I think showing the committed memory is more useful in the overview.
