Possible Mistakes

Make sure that the following options are configured as described in your configuration file for each Beat.
Otherwise it is possible that the Beat Agents wont’t be able to connect to your Backend or report a wave of errors.

setup.ilm.enabled: false
  xpack.enabled: false
setup.template.settings:
  index.number_of_shards: 1
processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~
  - add_docker_metadata: ~
  - add_kubernetes_metadata: ~
  1. Disable the Index lifecycle Management by setting the value to false
  2. Remove the setup.template.settings part (As both of these Configurations are being handled in the Backend)
  3. xpack is not supported
