.....
  host: "https://dlp.srv.world:5601"
# line 87: specify output host

# the default is localhost's Elasticsearch

# if output to Logstash, comment out Elasticsearch and uncomment logstash lines

# line 1172: if use Kibana, uncomment and specify output host

# if SSL is enabled on Kibana, uncomment ssl related lines

# if your certs is self-siged one, ssl.verification_mode should be "none"

setup.kibana:

  # Kibana Host
  # Scheme and port can be left out and will be set to the default (http and 5601)
  # In case you specify and additional path, the scheme is required: http://localhost:5601/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
  host: "dlp.srv.world:5601"

  # Optional protocol and basic auth credentials.
  protocol: "https"
  #username: "elastic"
  #password: "changeme"

  # Optional HTTP Path
  #path: ""

  # Use SSL settings for HTTPS. Default is true.
  ssl.enabled: true

  # Configure SSL verification mode. If `none` is configured, all server hosts
  # and certificates will be accepted. In this mode, SSL based connections are
  # susceptible to man-in-the-middle attacks. Use only for testing. Default is
  # `full`.
  ssl.verification_mode: none
