I think I get it better now. But it might be confusing because all the processes have the same name
😉So, from the last graph you sent (the process connections one), I believe that the values that are in the red squares are the sum of incoming/outgoing retransmissions.
Not sure yet what the first graph is, but if the second graph (the one with "Retransmissions received" in yellow) is what I think, it is related to the process highlighted in the middle of your last graph. So, if there are retransmissions received there, it means that the two processes to the right are retransmitting packets to the one in the middle. Now, that doesn't say much, as packets might be lost on either way of their transit.
Now, the percentage of retransmissions might seem high, but in fact the whole quantity is low. That is confirmed by the little amount of traffic. So, it wont be that bad. There is one problematic aspect though, as the retransmissions seem to be very steady.
If the servers that support these processes are in the same datacenter, than I would say that this is a problem. But, given the circunstances, I would almost bet they are connected by a WAN, in which case I would not consider these values problematic.
In any case, you will probably get a faster explanation if you could get a network capture. Given that it's so much little data, it should be pretty fast do determinate what's going on here.
