Logstash-forwarder + SSL + HAProxy

Elastic Stack Logstash
1

Hello,

I am trying to setup an ELK stack but I have a question about Logstash-forwarder and SSL. My setup looks like this:

Logstash-forwarder -> HAProxy (VM) -> (2 VM's) Logstash/Redis -> (2 VM's) Logstash Indexer -> (1 physical server) ElasticSearch/Kibana

When generating the SSL cert and key pair for Logstash-forwarder what FQDN do I use since there will be two Logstash servers behind the HAProxy LB?

Thanks in advance for the help.

Depends, if you terminate SSL at HAProxy then that would be it, if not then you will need both of the LS VMs hostnames in there.
