I need to deploy scalable ELK stack (with further adding nodes), and I didn't find any complete tutorial for this - thats why I'm kindly asking you for help here.
I saw some partial descriptions how to do that so I imagine that architecture of this environment could looks like on below picture. But maybe I'm wrong.. please take a look.
The goal is: build HA EL stack with possibility to scale (add nodes). Kibana on the end can be just one (without HA). I know already that there is possible for connect KIbana to many Elastics so lets leave it this thread.
- Is my idea sensible ? is it possible at all ? if no please tell how to do this in other way. Best would be with link to some tutorial.
- If it is possible then:
a) how to configure Logstashes to connect with every Elastics ?
b) is this full mesh (on the picture) necessary or not ?
c) the logs in Logstashes wouldn't be doubled while will be written from two sites (from 2 haproxys) ?
Thanks in advance
