The Confluent Syslog Connector is used to move messages from Network devices into Kafka.
It can be used for free for 30 days, but after that does require a Confluent Enterprise license. Contact Confluent for more details.
Use the Confluent Hub client to install this connector with:
confluent-hub install confluentinc/kafka-connect-syslog:1.0.0-preview
Or download the ZIP file and extract it into one of the directories that is listed on the Connect worker's plugin.path configuration properties. This must be done on each of the installations where Connect will be run. See here for more detailed instructions.
Once installed, you can then create a connector configuration file with the connector's settings, and deploy that to a Connect worker. See here for more detailed instructions.
