[2] Configure basic settings and start Packetbeat.
[root@dlp ~]#
vi /etc/packetbeat/packetbeat.yml
# line 29: set items to collect data

# if disable ICMPv4/ICMPv6, turn to false

# line 34 and later : many items are targeted as monitoring by default,

# but if not need, comment out the line [ports: ***]

packetbeat.protocols:
- type: icmp
  # Enable ICMPv4 and ICMPv6 monitoring. Default: false
  enabled: true

  # the AMQP protocol by commenting out the list of ports.
  ports: [5672]

# line 146: if use Kibana, uncomment and specify output host

# if SSL is enabled on Kibana, hostname should be the same with the hostname in certs

setup.kibana:
.....
  host: "https://dlp.srv.world:5601"
# line 166: specify output host

# the default is localhost's Elasticsearch

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

output.elasticsearch:
  # Array of hosts to connect to.l
  hosts: ["localhost:9200"]

.....

#output.logstash:
  # The Logstash hosts
  #hosts: ["localhost:5044"]
[root@dlp ~]#
vi /etc/packetbeat/packetbeat.reference.yml
# 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
