> AllocatedGB and AvailableGB metrics are now integer type. If there are four
> times 500MB memory allocation to container, AllocatedGB is incremented four
> times by {{(int)500/1024}}, which means 0. That is, the memory size allocated
> is actually 2000MB, but the metrics shows 0GB. Let's use float type for these
> metrics.
