Hi  
I’m trying to setup a 3 nodes cluster all of them as cluster\_manager , data . Somehow kibana shows only 1 node.  
ip heap.percent ram.percent cpu load\_1m load\_5m load\_15m node.role node.roles cluster\_manager name  
172.31.35.94 3 75 0 0.18 0.21 0.23 dm cluster\_manager,data \* node-1

this is my opensearch.yml for all 3 nodes  
#cluster.initial\_cluster\_manager\_nodes: [“node-1”, “node-2”]  
cluster.initial\_cluster\_manager\_nodes: [“node-1”,“node-2”,“node-3”]

discovery.seed\_hosts: [“node-1”, “node-2”, “node-3”]

# Bootstrap the cluster using an initial set of cluster-manager-eligible nodes:

Hi @nkalvaku,

Could you share your full opensearch.yml (all three would be great) and your opensearch\_dashboards.yml

when sharing please use the “Preformatted text (Ctrl + e)”:

These files are from a new 3 node cluster . Dashboard is not setup yet.

My intention is to configure 3 nodes cluster all being cluster\_manager , data with dashboard. Question regarding dashboard , do we need to install it on any of 3 nodes , all of them or on a separate server ? I’m testing this on Ubuntu 22 on AWS. So far tried multiple attempts failing at some point. Don’t find a perfect doc anywhere .
