Greetings, I am new to ELK I am not getting it through the tutorials please help me in it. As I want to monitor different servers(5 Servers) So I want to know as to observe the servers live do i Need more than 1 Node? and also how to create replica Shards? For Using ELK Stack on live Server Is important to have replica Shard? Is it compulsory to have more than 1 Node to create replica Shards. If yes than How to create different Nodes?
Thanks & Regards Shrikan
