Additionally, an active Input must be present on the Graylog server that is capable of receiving form data (e.g. a HTTP input, TCP raw or syslog etc).\n\n### Patches\n\n### Workarounds\nNone, as long as the relatively rare prerequisites are met.\n\nAnalysis provided by Fabian Yamaguchi - Whirly Labs (Pty) Ltd",
