>
> See [https://bugs.openjdk.org/browse/JDK-8307059] , The Generational ZGC
> separate the Cycles and Pauses as Minor and Major,like this:
> * Old ZGC: "ZGC Cycles", "ZGC Pauses"
> * Generational ZGC: "ZGC Minor Cycles", "ZGC Minor Pauses", "ZGC Major
> Cycles", "ZGC Major Pauses"
> let us separate it same and give 2 new metric about these, may be better...
