Found this site while researching solutions to our memory usage issues since moving to OpenJDK1.8. It has provided a wealth of information that has greatly enhanced our understanding of the JVM GC activity. Much easier than pouring though the log files by hand! If I could only convince management to pay for a subscription...

I see the log says "Total time for which application threads were stopped: 28.2856809 seconds", but this report says the max pause is less than 1 second.
