What is jHiccup?
jHiccup is an open source tool designed to measure the pauses and stalls (or “hiccups”) associated with an application’s underlying Java runtime platform. The new tool captures the aggregate effects of the Java Virtual Machine (JVM), operating system, hypervisor (if used) and hardware on application stalls and response time.
jHiccup allows developers, systems operators and performance engineers to easily create and analyze response time profiles, and to clearly identify whether causes of application delays reside in the application code or in the underlying runtime platform. jHiccup is completely transparent and non-intrusive to the application, has zero performance overhead in operation, and is compatible with all Java applications using any JVM.
