• c039fff [ZGC] Add GC ID to the ZGCCycle (#229)

The GC id can be useful when analyzing data and may be valuable to users. It can help order data later or give an indication of how many GC cycles have happened since since the process start or between points in time. (Jeff Bahr)

• cbb52a8 [ZGC] Improve parsing for Java 17 style output (#228)

ZGC was marked production ready in Java 17. There were a number of changes made to the ZGC log output in the past 2-3 years that have made it into the 17 release. I've updated the tests with samples from a Java 17 run on a sample app to test changes made to the ZGCCycle class. Java sample app was invoked with the following flag -Xlog:gc=info,gc+start=info,gc+phases=info,gc+load=info,gc+mmu=info,gc+marking=info,gc+metaspace=info,gc+nmethod=info,gc+ref=info,gc+reloc=info,gc+heap=info:file=/logs/gclog:level,tags,uptime:filecount=10,filesize=250m (Jeff Bahr)

• cec86bf [ZGC][parser] Ensure that ZGCMemoryPoolSummary and OccupancySummary use kilobytes (#227)

• [zgc][parser] Ensure that ZGCMemoryPoolSummary and OccupancySummary receive values normalized to kilobytes. The code in its current form will return a double without taking into account the units associated with the memory. This can lead to multiple GC cycles that report odd results. This diff ensures that as they are parsed the are normalized to a long in terms of kilobytes (Jeffrey Bahr)
