Hi Matija, All nodes are UP & running and even GC patterns are all well. But I see lot of "Timed out replaying hints" in HintedHandOff Manger, I suspect this might be the reason why GBs of hints getting piled up instead of proper delivery. So this clearly indicates some network related issues , so just wanted to know the way to monitor hints delivery throughput and also tcp throughput(packets sent, received ,dropped etc., on an interface).
If anyone monitoring such stats, please let me know.
