Need server/system serial number output in kibana dashboard

Hi,

I have build my ELK stack on local machine (ELK version- 6.8.10) . In order to get more details like machine/server serial number, I have added few entries in filebeat.yml file.

After adding few lines under add_host_metadata section, I took restart of filebeat service and post that service is successfully up and running fine.

But I am not able to view serial_number field in my kibana dashboard (after discovering filebeat index). Also there is one field in filebeat output which is "host.id" , I have no idea that what information is this ?? I have already crossed checked my instance and serial number with host.id output , unfortunately it is not matching with any of the outputs.

Please have a look on below filebeat.yml file and share further suggestion to resolve this issue ASAP. :slight_smile:

###################### Filebeat Configuration Example #########################

This file is an example configuration file highlighting only the most common

options. The filebeat.reference.yml file from the same directory contains all the

supported options with more comments. You can use it as a reference.

You can find the full configuration reference here:

https://www.elastic.co/guide/en/beats/filebeat/index.html

For more available modules and options, please see the filebeat.reference.yml sample

configuration file.

#=========================== Filebeat inputs =============================

filebeat.inputs:

Each - is an input. Most options can be set at the input level, so

you can use different inputs for various configurations.

Below are the input specific configurations.

  • type: log

    Change to true to enable this input configuration.

    enabled: false

    Paths that should be crawled and fetched. Glob based paths.

    paths:

    • /var/log/*.log
      #- c:\programdata\elasticsearch\logs*

    Exclude lines. A list of regular expressions to match. It drops the lines that are

    matching any regular expression from the list.

    #exclude_lines: ['^DBG']

    Include lines. A list of regular expressions to match. It exports the lines that are

    matching any regular expression from the list.

    #include_lines: ['^ERR', '^WARN']

    Exclude files. A list of regular expressions to match. Filebeat drops the files that

    are matching any regular expression from the list. By default, no files are dropped.

    #exclude_files: ['.gz$']

    Optional additional fields. These fields can be freely picked

    to add additional information to the crawled log files for filtering

    #fields:

    level: debug

    review: 1

    Multiline options

    Multiline can be used for log messages spanning multiple lines. This is common

    for Java Stack Traces or C-Line Continuation

    The regexp Pattern that has to be matched. The example pattern matches all lines starting with [

    #multiline.pattern: ^[

    Defines if the pattern set under pattern should be negated or not. Default is false.

    #multiline.negate: false

    Match can be set to "after" or "before". It is used to define if lines should be append to a pattern

    that was (not) matched before or after or as long as a pattern is not matched based on negate.

    Note: After is the equivalent to previous and before is the equivalent to to next in Logstash

    #multiline.match: after

#============================= Filebeat modules ===============================

filebeat.config.modules:

Glob pattern for configuration loading

path: ${path.config}/modules.d/*.yml

Set to true to enable config reloading

reload.enabled: false

Period on which files under path should be checked for changes

#reload.period: 10s

#==================== Elasticsearch template setting ==========================

setup.template.settings:
index.number_of_shards: 3
#index.codec: best_compression
#_source.enabled: false

#================================ General =====================================

The name of the shipper that publishes the network data. It can be used to group

all the transactions sent by a single shipper in the web interface.

#name:

The tags of the shipper are included in their own field with each

transaction published.

#tags: ["service-X", "web-tier"]

Optional fields that you can specify to add additional information to the

output.

#fields:

env: staging

#============================== Dashboards =====================================

These settings control loading the sample dashboards to the Kibana index. Loading

the dashboards is disabled by default and can be enabled either by setting the

options here, or by using the -setup CLI flag or the setup command.

#setup.dashboards.enabled: false

The URL from where to download the dashboards archive. By default this URL

has a value which is computed based on the Beat name and version. For released

versions, this URL points to the dashboard archive on the artifacts.elastic.co

website.

#setup.dashboards.url:

#============================== Kibana =====================================

Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.

This requires a Kibana endpoint configuration.

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: "localhost:5601"

Kibana Space ID

ID of the Kibana Space into which the dashboards should be loaded. By default,

the Default Space will be used.

#space.id:

#============================= Elastic Cloud ==================================

These settings simplify using filebeat with the Elastic Cloud (https://cloud.elastic.co/).

The cloud.id setting overwrites the output.elasticsearch.hosts and

setup.kibana.host options.

You can find the cloud.id in the Elastic Cloud web UI.

#cloud.id:

The cloud.auth setting overwrites the output.elasticsearch.username and

output.elasticsearch.password settings. The format is <user>:<pass>.

#cloud.auth:

#================================ Outputs =====================================

Configure what output to use when sending the data collected by the beat.

#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:

Array of hosts to connect to.

hosts: ["localhost:9200"]

Enabled ilm (beta) to use index lifecycle management instead daily indices.

#ilm.enabled: false

Optional protocol and basic auth credentials.

#protocol: "https"
#username: "elastic"
#password: "changeme"

#----------------------------- Logstash output --------------------------------
output.logstash:

The Logstash hosts

hosts: ["localhost:5044"]

Optional SSL. By default is off.

List of root certificates for HTTPS server verifications

#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]

Certificate for SSL client authentication

#ssl.certificate: "/etc/pki/client/cert.pem"

Client Certificate Key

#ssl.key: "/etc/pki/client/cert.key"

#================================ Processors =====================================

Configure processors to enhance or manipulate events generated by the beat.

processors:

  • add_host_metadata:
    server_details:
    name: xxxxxx
    serial_number: 0000-0009-3938-xxx-3444-06
  • add_cloud_metadata: ~

#================================ Logging =====================================

Sets log level. The default log level is info.

Available log levels are: error, warning, info, debug

#logging.level: debug

At debug level, you can selectively enable logging only for some components.

To enable all selectors use ["*"]. Examples of other selectors are "beat",

"publish", "service".

#logging.selectors: ["*"]

#============================== Xpack Monitoring ===============================

filebeat can export internal metrics to a central Elasticsearch monitoring

cluster. This requires xpack monitoring to be enabled in Elasticsearch. The

reporting is disabled by default.

Set to true to enable the monitoring reporter.

#xpack.monitoring.enabled: false

Uncomment to send the metrics to Elasticsearch. Most settings from the

Elasticsearch output are accepted here as well. Any setting that is not set is

automatically inherited from the Elasticsearch output configuration, so if you

have the Elasticsearch output configured, you can simply uncomment the

following line.

#xpack.monitoring.elasticsearch:
