Lenses requires these Kafka topics to be available, otherwise it will try to create them. The topics can be created manually before Lenses is run, or allow Lenses the correct Kafka ACLs to create the topics:
1
3
__topology
__topology__metrics
_kafka_lenses_metrics
To allow for fine-grained control over the replication factor of the three topics, the following settings are available:
lenses.topics.external.topology
lenses.topics.external.metrics
lenses.topics.metrics
