Iprobe is a low-overhead toolsuite that uses the Alpha event counters to find performance bottlenecks in kernel and userspace. Internally, Iprobe has been used to optimize performance in benchmarks (SPEC CPU95), operating systems (VMS, Digital Unix, Windows NT) and databases (Oracle, and Informix). Iprobe has traditionally been a cross-platform alpha tool. It runs on Digital Unix, Open VMS, and Windows NT, and it is now being released under GPL for Alpha/Linux.
Release Notes: This is the first public release and it is also the first release to run on Alpha/Linux.
