What Node to I point to

I have a cluster with 3 x Master, 4 x Hot, 4 x Warm and 2 x Ingest.

With Kibana and when I want to send data to the cluster, what is the recommended set of nodes to point to? Is it just the Masters, Hot or Warm nodes or should I point at all of them?

Since you have master dedicated nodes, you should avoid sending any request to them.

With dedicated ingest nodes I would recommend to send data to these nodes and configure Kibana to query the hot nodes.

Excellent - Thanks!

Actually another related one: when i spin up a new node in the cluster, what should I put as the seeds?

The setting discovery.seed_hosts need to have only the master-eligible nodes on the cluster as explained in the documentation.
