Packetbeat Configuration Example

  1. To successfully ship logs to Graylog, ensure you add the IP address of your Graylog instance within your packetbeat.yml file. For example:

    Copy
    # ------------------------------ Logstash Output
                        -------------------------------
                        output.logstash:
                        # The Logstash hosts
                        hosts: ["192.168.x.x:5044"]
