我正在使用以下设置运行java应用程序：

-XX：CMSParallelRemarkEnabled

-XX：UseConcMarkSweepGC

-XX：UseParNewGC

-XX：PrintGCApplicationStoppedTime

-XX：PrintGCApplicationConcurrentTime

-XX：PrintGCDetails

-XX：PrintGCTimeStamps

-XX：PrintGCDateStamps

-XX：PrintHeapAtGC

-XX：PrintTenuringDistribution

我不确定如何解释相关的gc日志(如下) . 特别是：

Heap after GC invocations=31 (full 3) ：这是否意味着有31个小型GC和3个完整的GC？

什么触发 Total time for which the application threads were stopped 和 Application Time 的几个连续行？是否有可能获得与这些线相关的时间戳？
