Hi : ),
I am creating a new multi node installation which look as follows:
- 3 Graylog Nodes
- 3 Elasticsearch Master Nodes
- 1 Elasticsearch Data Node (I am planning to add more data nodes in the future)
Could you tell me please which elasticsearch hosts I should include in the Graylog configuration file?
Shall I add only elasticsearch master nodes or I should add all nodes (master + data nodes)?
Thank you in advance.
- OS Information: The Graylog/Elasticsearch nodes are running Ubuntu Server 22.04
- Package Version:

welcome to the Community!
I haven’t found any documentation about that while I was setting up our 3x nodes OpenSearch (OS) cluster. WIth that said, our Graylog cluster points to all OS members (master and data roles), and everything works fine.
Hello && Welocm @mobk
In the documentation here
Basically what I did with 6 node cluster 3 ES & 3 GL/Mongo.
This was configure on each graylog node.
elasticsearch_hosts = http://10.10.10.10:9200, http://10.10.10.20:9200, http://10.10.10.30:9200
Depending on how the cluster is set up you could use something like this
This was only done for ES master nodes since they ingest from Graylogs journal.
Probably a better way would be a load balancer, if you expanding larger then three nodes. It would make this task much easier down the road.
