For other versions, see the All of its options are exposed to the plugin. Only one output is needed on the Beats side, and the separation of the event streams happens inside Logstash. Add a unique ID to the plugin configuration. Each instance of the plugin assigns itself to a specific consumer group (logstash by default). -1 is the safest option, where it waits for an acknowledgement from all replicas that the data has been written. This sounds like a good use case for RabbitMQ. Kafka is a distributed, partitioned, replicated commit log service. Separate input logstash kafka plugins per topic.
