The record

Purpose: async-profiler is a low-overhead sampling profiler for Java that avoids the safepoint bias problem.
Runtime support: It works with OpenJDK and other Java runtimes based on the HotSpot JVM.
Native visibility: It monitors non-Java threads and shows native and kernel frames in stack traces.
Profiling targets: It can profile CPU time, Java-heap allocations, native-memory allocations and leaks, contended locks, and hardware or software performance counters.
Output: The profiler can save results as an interactive Flame Graph viewable in a browser.
Output formats: Supported output formats include collapsed stacks, flame graphs, HTML tree views, and text.
Official builds: Officially maintained builds are provided for Linux x64 and arm64 and macOS x64 and arm64.
Nightly retention: Nightly binaries for previous commits are kept for 30 days.
Build requirements: Building requires make, GCC 7.5.0+ or Clang 7.0.0+, static libstdc++, and JDK 11+.
Java integration: A Java API is published to Maven Central and can be used as a Maven dependency.
Span API: The Span API records latency-sensitive intervals into the same JFR recording as profiling samples and is allocation-free.
IDE integration: IntelliJ IDEA bundles async-profiler and exposes it through the Java Profiler settings.
Container profiling: It can profile Java processes in Docker or LXC containers from inside the container or from the host system.
Security reporting: Security issues should be reported to AWS/Amazon Security through its vulnerability reporting page instead of a public GitHub issue.
