Subject Heavy traffic between Kafka nodes
Date Fri, 23 Dec 2016 10:08:23 GMT
Hi,

I have a two node Kafka cluster, and I'm catching some unusual "TCP
retransmission" metrics from my monitoring. I did found out that the
network is a bit overloaded and most of it it's because the communication
between both nodes is too chatty.

It seems that there's more traffic between the nodes than coming/going
from/to all producers/consumers.

Is this normal? Any suggestions of what might be wrong?

best,

Herbert
