output_module_kafka_security_protocol = SASL_PLAINTEXT

To make sure I understand fully, are you looking to send logs FROM kafka TO graylog (kafka → graylog), OR
FROM graylog TO kafka (graylog → kafka).

Thanks.

I’m looking to forward logs from graylog to Kafka topic with SASL authentication.

Could you please assist me to transfer logs from Graylog to Kafka topic with SASL credentials.

As far as I know there is no official or supported way to output messages from graylog to kafka. I did find an unofficial output plugin, but i have not tested it and its several years old so may no longer work. GitHub - asnowfox/graylog-kafka-output . I’m also not clear on if it supports SASL.

I also found this document graylog-guide-syslog-kafka/README.md at master · Graylog2/graylog-guide-syslog-kafka · GitHub but it more so talks about ingesting messages in kafak and then sending to graylog.
