Questions On Logstash Conf File

Elastic Stack Logstash
2

Your when using an architecture like

Beats > Logstash > Elasticsearch

Your Logstash conf file should look like the following

################################################
# beats->logstash->es default config.
################################################
input {
  beats {
    port => 5044
  }
}

output {
  if [@metadata][pipeline] {
    elasticsearch {
      hosts => "http://localhost:9200"
      manage_template => false
      index => "%{[@metadata][beat]}-%{[@metadata][version]}"
      pipeline => "%{[@metadata][pipeline]}" 
      user => "elastic"
      password => "secret"
    }
  } else {
    elasticsearch {
      hosts => "http://localhost:9200"
      manage_template => false
      index => "%{[@metadata][beat]}-%{[@metadata][version]}"
      user => "elastic"
      password => "secret"
    }
  }
}

I also answered some additional detail about this architecture in this post

It happens to be metricbeat but it's very similar for winlogbeat
