Cluster nodes not showing in Graylog gui

Graylog Central (peer support)
1

Hi all,

Set up is: 1 Graylog server and 2 elasticsearch nodes

Host - Ubuntu 18.04
Graylog - 3.0.1
Java - 1.8.0_191
Elasticsearch - 6.7.1
MongoDB - 4.0.6

I have added both nodes to the cluster and are both pulling data, but there not showing in the graylog gui

ES node conf is as followed

node.name: node2.graylog
path.data: /mnt/es/data
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: [“173.25.229.162”, “173.25.229.60”,“173.25.229.227”]
action.auto_create_index: false
node.master: false
node.data: true
node.ingest: false

There aren’t any errors in the ES node logs and the graylog host. Any one got any ideas what it could be?

GL UI will shows only the GL nodes.
It doesn’t shows the ES nodes.
Under Elasticsearch cluster you see only the status of the ES cluster, not the nodes.

As I see you sent the ES config, so I think you talked about the ES cluster, not the Graylog.

Thanks, makes more sense.

Apart from fail over or load balancing, are there any other benefits to having a multi cluster graylog server. Reason for asking is I have a backup system and my environment is virtual which removes the need for fail over.

//At a simple way…
GL nodes working independently. You got only a common UI.
If a node got a message it will process the message, and write it to ES. So no connection with other nodes IN the processing.
So if you don’t need backup node, overbalancing, etc, you can run 1 node.
