This looks like a good basic configuration.

You should add a note that this is for a read-heavy ES cluster.

If you have a write-heavy cluster (thinking ELK), you'll want a different config with more focus on bulk and index.

Well, thanks for your comment. Actually I don't know the difference between read-heavy and write-heavy cluster, could you be more explicit? By the way I have ELK so according to you it should be write-heavy cluster, can you suggest me any configuration or show me where to look?
