CLIF

CLIF provides a flexible, extensible Java-based platform for scalable, distributed load injection and performance testing. With the Eclipse-based GUI, use provided or custom load injectors and probes, and run up to millions of vUsers per injector!

CLIF is an open load testing platform, including load injectors, for generating traffic (a variety of protocols are supported such as HTTP, FTP, SIP...) and probes, for measuring resource usage (processor, memory, network...).

CLIF comes with test supervision features (including monitoring of response times, throughput, error rate, computing resources consumption), and analysis tools. Both command-line and graphical user interfaces are provided, including Eclipse plug-ins.  CLIF is extensible through Java programming (new injectors, new probes...).

With CLIF you'll get a powerful framework that was designed especially for load injection and perfomance evaluation.
