 **[1]**: Pool names are generally obtained via [MemoryPoolMXBean#getName()](https://docs.oracle.com/en/java/javase/11/docs/api/java.management/java/lang/management/MemoryPoolMXBean.html#getName()).
 Examples include `G1 Old Gen`, `G1 Eden space`, `G1 Survivor Space`, `Metaspace`, etc.
 **[2]**: These utilizations are not defined as being for the specific interval since last measurement (unlike `system.cpu.utilization`).
