jHiccup is an Open Source tool developed by Azul CTO Gil Tene that provides a quick picture of your applications as they run in production.

jHiccup generates “hiccup charts” that quickly show the latency inherent in your system, to the 99.9999th percentile.

Hiccup charts also show the system latency across the entire test interval. At Azul we use jHiccup to quickly show the impact of Zing on live applications. jHiccup has minimal overhead, is written in Java, and it is free.
