+###################### 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: true
+
+  # Paths that should be crawled and fetched. Glob based paths.
+  paths:
+    - /var/log/connector-app/*.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.

+  # 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:
+     tags: ['json']
+  #  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

+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

+
+# Optional fields that you can specify to add additional information to the
+# output.
+fields:
+  build.profile: ${BUILD_PROFILE}
+#  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
+# 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"]
+
+  # 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: ~
+  - add_cloud_metadata: ~
+  - drop_fields:
+      fields: ["beat.name", "beat.hostname", "beat.version", "host.os.family", "host.os.version", "host.architecture", "host.containerized"]
+
+#================================ 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.
+#monitoring.enabled: false
+
+# 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
