I use 4 VMWare VM nodes and plan to implement 4 nodes cluster for graylog,elasticsearch and mongodb.
So far I have elasticsearch form a 4 nodes clusters and have 4 graylog server activate with only 1 master on 4 nodes.
Problem from graylog GUI of each nodes, I only see 2 nodes are listed like below.
Understand graylog can’t auto failover by automatically yet.
Is this display 2 out of 4 nodes expected ?
