## プロジェクトの歴史と使われ方

async-profiler is a low-overhead sampling profiler for HotSpot-based Java runtimes. Its package-manager identity is unusually strong because the everyday tool is a small native CLI, `asprof`, that produces artifacts Java engineers already trade around: flame graphs, collapsed stacks, JFR recordings, traces, trees, heatmaps, and converter outputs.

### プロジェクトの歴史

The project started in 2016 with an initial proof of concept for profiling Java without the safepoint bias that affected many traditional JVM profilers. The README describes the core design as combining HotSpot-specific stack collection with native facilities such as perf events, so it can show Java frames alongside native, kernel, GC, and JIT compiler activity.

Over time async-profiler grew from a CPU sampler into a broader observability utility. Official documentation now covers CPU, allocation, native memory, lock, wall-clock, hardware/software counter, container, Java Flight Recorder, FlameGraph, OTLP, pprof, and converter workflows.

### 採用の歴史

The project became a default recommendation in the JVM performance community because it is scriptable, produces portable output, and does not require a heavyweight GUI profiler. The package is distributed through Homebrew, MacPorts, and Nix in the supplied package metadata, while upstream publishes Linux and macOS binaries plus nightly builds from GitHub Actions.

Recent 4.x releases show continued production-oriented maintenance rather than archival status: v4.3 added native lock profiling, latency filtering, Prometheus-format metrics, and Java-agent/JMX control, while v4.4 added differential flame graphs and call-trace memory limits.

### 使われ方

The normal package-manager workflow is to install the CLI and run `asprof` against a live JVM PID, for example saving a 30-second profile to an HTML flame graph. More advanced workflows attach it as a Java agent, run continuous loops, emit JFR/OTLP/pprof-compatible data, or convert recordings with the bundled converter tooling.

### パッケージ好きにとっての重要性

async-profiler is one of those packages whose formula matters more than its size suggests: a native tool with JVM-specific privileges, OS-specific packaging, architecture-specific binaries, and output formats that plug into a large performance-debugging ecosystem. It is also a good example of a CLI package that package managers make discoverable to users who otherwise would only encounter it through conference talks or performance postmortems.

### タイムライン

- 2016: Initial Git commit and proof-of-concept async profiler work.
- v1.x: Early public release series established the standalone profiler package.
- 2026: v4.3 added native lock profiling, latency filtering, Prometheus metrics, and Java-agent/JMX control.
- 2026: v4.4 added differential flame graphs and further FlameGraph/JFR/OTLP improvements.

### Related projects

- The project sits near HotSpot, Linux perf events, Java Flight Recorder, Brendan Gregg-style FlameGraphs, OpenTelemetry, and pprof-style profiling workflows.
