> 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.
