SYSLOG SOURCE CONNECTOR
It is often useful to re-key Apache Kafka® Source Records host field’s value as an IP address into a resolved hostname for that IP address. The Hostname Resolver Transformation makes this easy. This transformation will perform a reverse DNS lookup to replace IP addresses with hostnames. For example, 127.0.0.1 will be replaced with localhost on most machines.
