hi,  
I have an issue to start filebeat...Error message is: failed to start: Exiting: error loading config file: yaml: line 31: did not find expected key  
filebeat version 7.5.1 (amd64), libbeat 7.5.1

yml file below

Thanks for your help  
###################### 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](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
    - type: udp
      max_message_size: 10MiB
      host: "0.0.0.0:514"
      fields:
      logzio_codec: plain
      token: cCNykNugBZfvXWmznbTxQUAjZZOxHzFz
      type: checkpoint
      fields_under_root: true
      encoding: utf-8
      ignore_older: 3h

```

# Change to true to enable this input configuration.

enabled: true

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

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

filebeat.registry.path: /var/lib/filebeat  
processors:  
- rename:  
fields:  
- from: "agent"  
to: "beat\_agent"  
ignore\_missing: true  
- rename:  
fields:

ignore\_missing: true

# 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: 1  
#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` 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](http://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](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/](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"]

# Optional protocol and basic auth credentials.

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

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

# The Logstash hosts

hosts: ["[listener-eu.logz.io:5015](http://listener-eu.logz.io:5015)"]  
ssl:  
certificate\_authorities:['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']

# 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: ~
- add\_cloud\_metadata: ~
- add\_docker\_metadata: ~
- add\_kubernetes\_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: ["\*"]

#============================== X-Pack 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.

#monitoring.enabled: false

# Sets the UUID of the Elasticsearch cluster under which monitoring data for this

# Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch

# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.

#monitoring.cluster\_uuid:

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

# Elasticsearch output are accepted here as well.

# Note that the settings should point to your Elasticsearch _monitoring_ cluster.

# Any setting that is not set is automatically inherited from the Elasticsearch

# output configuration, so if you have the Elasticsearch output configured such

# that it is pointing to your Elasticsearch monitoring cluster, you can simply

# uncomment the following line.

#monitoring.elasticsearch:

#================================= Migration ==================================

# This allows to enable 6.7 migration aliases

#migration.6\_to\_7.enabled: true
