Logstash Master Setup on AWS

AWS Configurations

• Port 80 should be open on the server so kibana can be accessed
• Port 5000 should be open for incoming traffic via logstash-forwarder aka lumberjack (this is where logstash data comes in). I set this to 0.0.0.0/0 although you could restrict it to just the internal machines you are monitoring.

MASTER: ElasticSearch Install
