Hi
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 ?
Are all Graylog nodes using the same MongoDB database?
Do all Graylog nodes have a unique node ID (see node_id_file).
@jochen, Thanks for the pointer on node_id. Indeed, node 2 was manually build but later clone to node 3 and 4. So they had same node_id. After the node_id adjustment. All four nodes are showing up. Thanks for your quick reply.
