ELK License

Elastic Stack Elasticsearch

Currently, we're using licensed ELK-Stack
Does using an independent coordinator node consume a node-license?

Example: Let's assume, we've 4 node license. and we've already used 4 nodes for Master & Data. Now, we need a standalone coordinator node. So, adding a coordinator node count as a new license?

If you're using the cost-free Basic Elastic License then it covers as many nodes as you want.

If you have one of the paid licenses (Gold, Platinum etc.) then your account rep or the support team will be able to help you with this question.
