I'm a performance test engineer. I've been using jvmtop for a few months to monitor JVM statistics. As I've tallied the output with Jconsole, I've mostly observed similar stats in jvmtop as well.
However during a recent test execution I've observed few entries of CPU% to go above 100% (120% being the highest). Now as I believe jvmtop provides cumulative CPU usage (not like top which provides more of core-wise details), need guidance on how to interpret this entries of beyond 100% usage.
