> - Abstract Sink checks if there is local known monitor port available to write (e.g.: 61888)
> - Handshake / Ping to make sure its the monitor and is accepting writes
> - Start sending metrics only to the monitor
> - Monitor sends metrics at the global send interval (1 minute) with all the granularity of the sink
> - Monitor aggregates first interval (5 min) data and sends it every interval seconds. (5 min)
> - The monitor interface look the same as that of collector (http server: maybe Flask)
> - Security concerns need to be addressed as well. (https/spnego?)
