My Elasticsearch cluster is split in fast and slow nodes. If I am manually querying by REST, I'll use the preference query parameter (https://www.elastic.co/guide/en/elasticsearch/reference/7.17/search-search.html#search-preference) to specify that I'd like the search to occur on a fast node.

I can't do the same in Kibana so how can I setup such that Elasticsearch/Kibana will search on the fast nodes if they are available, falling back to the replicas on the slow nodes as required?

You can change the way Kibana specifies the preference parameter by configuring this in Stack Management > Advanced Settings and then changing the following settings:

• courier:setRequestPreference = Custom (instead of SessionID)
• courier:customRequestPreference = _only_nodes:

Then it should work the way you expect.
