## Historique du projet et usages

jHiccup is Gil Tene's Java latency-observation tool for measuring platform pauses, including JVM stalls and operating-system or hardware scheduling noise. It records the delays a Java application experiences when it is not continuously runnable.

### Historique du projet

The public repository was created in 2013 and the README identifies the author as Gil Tene of Azul Systems. The first tagged line visible in the repository is jHiccup 1.3.5 from November 2013, and the 2.0.x line reached 2.0.10 in 2018.

The tool reflects Azul's long-running focus on Java pause behavior. It can run as a Java agent, attach to an already running process, or wrap an existing Java command, making it practical for production-like measurements without rewriting the application under test.

### Historique d'adoption

jHiccup spread among JVM performance engineers because it measures latency symptoms from the application's point of view rather than only reporting garbage-collector events. Azul's product page and Prime documentation keep it available as an open-source component and describe its use in evaluating JVM runtime pauses.

Its package-manager footprint is narrower than general-purpose CLIs, but Homebrew and Nix packaging make sense: the audience is specialized, and the tool is most useful when an engineer can install it quickly on a machine under test.

### Modes d'utilisation

jHiccup starts a thread that sleeps at a small interval and records wake-up delays beyond the expected sleep time. It writes histogram logs that can be processed by jHiccupLogProcessor or viewed with HdrHistogram-based tools.

Common use cases include comparing JVM pause behavior, separating application-visible stalls from operating-system noise, attaching a control process for baseline idle hiccups, and producing charts for latency investigations.

### Pourquoi les passionnés de paquets s'y intéressent

For package nerds, jHiccup is a good example of a tiny diagnostic package with a highly specific audience. It packages an expert performance concept into command-line tools, a Java agent, and log-processing utilities rather than a full monitoring platform.

It is also historically tied to HdrHistogram and the Java low-latency community, where percentile distributions and pause visibility matter more than average throughput.

### Chronologie

- 2013: The public jHiccup repository was created and jHiccup 1.3.5 was tagged.
- 2018: jHiccup 2.0.10 was tagged.
- 2021: The README was updated with a Works with OpenJDK badge, reflecting continued compatibility signaling.

### Related projects

- HdrHistogram is the histogram format and library used by jHiccup logs.
- HistogramLogAnalyzer and HdrHistogramVisualizer are named by the README as tools for analyzing or plotting histogram logs.
- Azul Prime documentation uses jHiccup as part of JVM pause evaluation workflows.
