早上好，
我正在编写一个解析 Java 垃圾收集的程序，我需要一些帮助来确定日志输出的确切含义。我的日志文件包含以下我理解的输出：
46834.386: [Full GC 46834.386: [CMS: 412190K->414324K(8388608K), 2.9557920 secs] 4319571K->414324K(16769088K), [CMS Perm : 96586K->96555K(2097152K)], 2.9561693 secs]
49394.883: [GC 49394.883: [ParNew: 8372352K->0K(8380480K), 0.0256383 secs] 8786676K->422169K(16769088K), 0.0258842 secs]
但它还包含以下我不太了解的输出：
CMS: abort preclean due to time 2087298.141: [CMS-concurrent-abortable-preclean:
0.680/1.055 secs]
2087298.146: [GC[YG occupancy: 7515768 K (8380480 K)]2087298.146: [Rescan (parallel) , 5.0710721 secs]2087303.217: [weak refs processing, 0.0718252 secs] [1 CMS-remark: 3769931K(8388608K)] 11285700K(16769088K), 5.1432270 secs]

目前我正在使用正则表达式来分隔具有顶部格式的日志输出。它根据 eden/tenured 垃圾收集分离输出。我现在的问题是，底部的这些日志输出语句是什么？他们是伊甸园还是终身垃圾收集？
谢谢你的时间。
