FreeNote

FreeNote is a distributed system for Internet metrics monitoring currently under development by Petta Technology. The FreeNote system consists of an open source probe running on geographically and topologically distinct computers across the world, and a collection system to retrieve and process data from the probes. Unlike proprietary Internet metrics systems, FreeNote's data will be available publicly, and anyone will be able to get their site monitored as long as they also contribute to running probes. We hope that this service allows Open Source projects and small companies to take advantage of Internet metrics monitoring without expense --- and that larger companies will be able to save significant amounts of money by taking advantage of FreeNote.
