NightStar is a suite of debugging and analysis tools for Linux software development. NightStar tools are minimally intrusive, allowing users to locate bugs, find timing bottlenecks, and analyze multi-threaded and multi-process interactions while preserving application execution behavior and determinism. NightStar includes a complete source-level debugger, a trace utility that offers a graphic view of kernel interactions, a data monitor, and a system and application performance tuner.
