Rule Entry Node

Every routing rule must start with the Rule Entry node.

Kafka Pub Node

The Kafka Pub node establishes a Kafka client that publish messages to a third-party Kafka server. Since the alert source only supports Kafka messages within the cluster, the Kafka component host needs to use the Kafka host in the cluster.

  1. Enter the host and topic.
  2. Select Anonymous from the Authentication Method drop-down.
