In System Info, the value of Total memory is the value of <heap-used> in application.xml.

When looking at Total Memory, if the memory moves into gigabytes, there is not much granularity to see the actual value being using. We round-up to the nearest gigabyte.

For example, is 1.5GB is used, it will show 1G.

In the following screen shot we can see Total Memory shown as 9G:

However, application.xml from the same FishEye instance, created by the Support Tools Plugin almost at the same time, reports:

<heap-used>8,531,214,336</heap-used>

In this case the heap used is around 8.53G and, as we round-up to the nearest gigabyte, Total memory is showing up as 9G.

More granularity should be added (i.e. 1.5G or 1.50G) to make the metric more useful for administrators.

This should be applied to Free Memory as well.
