Sometimes, an incident will appear on senhasegura orbit panel, called “Replication Issues Prevention”:
The incident report states: “The node cannot apply write-sets as quickly as it receives them”.
This means that senhasegura is receiving the data from the others nodes, but writing on the database is so high.
This warning come followed by a number at the end, the smaller the better, and when this number gets 0 (zero) the alert will disappear, so you do not need to worry about it.
