    A software to monitor quality of experience for live streaming video. It makes possible to track experience by observing several metrics like bitrate, dropped frames, location, bandwidth, number of rebuffers and session time.

    With these information it's more feasible to fix issues, improve the current solution and keep s engaged, for example, offer more specialized content.

    The final solution is a set of distributed system that was built using open source technologies like: logstash, graphite, redis, elastic search, nginx, angular, rails, ruby, lua, python and puppet for provisioning.
