Data flowing via Raw/Plaintext TCP but everything appears encoded

New user to Graylog/filebeat.

Data flowing in via Raw/Plaintext TCP appears garbled/encrypted/encoded. Most settings are still default. Using this input defn:

  • bind_address: 0.0.0.0
  • charset_name:
  • max_message_size: 2097152
  • number_worker_threads: 2
  • override_source:
  • port: 5044
  • recv_buffer_size: 1048576
  • tcp_keepalive: false
  • tls_cert_file:
  • tls_client_auth: disabled
  • tls_client_auth_cert_file:
  • tls_enable: false
  • tls_key_file:
  • tls_key_password: ********
  • use_null_delimiter: true

What am I missing?

Host#1 (Ubuntu 22), running filebeat to send syslogs/mysql/etc logs to Host#2 (graylog).

Are you using a raw input or the beats input? filebeat should be going to the beats input.
