How is collected counters stored internally ?

eye.lo architecture relies on proprietary TSDB, optimized for time series. Time Series data are stored every 5 minutes in read-only binary files. Map Reduce algorithms fetch and calculate values displayed on end-user graphs: this requires random, non linear access in those files, which explains why SSD drives is mandatory when eye.lo platform embeds more than a few hundreds of CPEs.

This optimized end-to-end architecture insures high responsiveness to end-users requests even for tens of thousands od CPEs.
