Hi,

Since I first saw Netflix post ( http://techblog.netflix.com/2015/07/java-in-flames.html ) using FlameGraph with Java I thought which use cases would suite to use this kind of tool, specially as there are many more tools like http://www.brendangregg.com/linuxperf.html . Could you talk a bit more about those tools (such as FlameGraph and also the linux system performance tools) , like some useful scripts and hacks you already created to solve an problem, the border line which separates them with other tools (such as JVisualVM, JProfile, thread dump, etc) and other advices please? =)

Thank you,
Luan
