Hi Prateek, the missing numbers are an artifact from how the stats are collected. ATM, Flink does only collect these metrics for data which is sent over connections *between* Flink operators. Since sources and sinks connect to external systems (and not Flink operators), the dash board does not show receiving byte for sources and sent bytes for sinks.
