> Async profiler ([https://github.com/jvm-profiling-tools/async-profiler]) is a
> low overhead sampling profiler for Java that does not suffer from Safepoint
> bias problem. It features HotSpot-specific APIs to collect stack traces and
> to track memory allocations. The profiler works with OpenJDK, Oracle JDK and
> other Java runtimes based on the HotSpot JVM.
> Async profiler can also profile heap allocations, lock contention, and HW
> performance counters in addition to CPU.
> We have an httpserver based servlet stack hence we can use HIVE-20202 as an
> implementation template to provide async profiler as servlet for Hadoop
> daemons. Ideally we achieve these requirements:
> * Retrieve flamegraph SVG generated from latest profile trace.
> * Online enable and disable of profiling activity. (async-profiler does not
> do instrumentation based profiling so this should not cause the code gen
> related perf problems of that other approach and can be safely toggled on and
> off while under production load.)
> * CPU profiling.
> * ALLOCATION profiling.
