Heartbeat to Logstash disappears in Elasticsearch (Indices)

How can I get Heartbeat to output to Logstash where I can manipulate it some? Right now the only way I can anything to appear in Elasticsearch/Kibana is to output directly to Elasticsearch and keep the default index name.

I guess what I really need is a gentle introduction to Elasticsearch indices. Will I have to write my own schema every time I change the index name?

What do you see happening if you send to Logstash?

Nothing.

I never see any indices in either Kibana or Curator.

heartbeat.yml:

#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
     hosts: ["localhost:5049"]
 

logstash pipeline:

input {
  beats {
    host => localhost
    port => 5049
#    host => 0.0.0.0
    id => aws_us_east
    }
    type => "http_monitor"
}

filter {}

output {
  
  elasticsearch {
    hosts => ["http://localhost:9200"]
    }
}

Is Logstash running on the same host as Heartbeat?
Is that your only Logstash config?
