Currently the available Kafka topics are discovered by extracting them from the kafka.log.Log.*
metrics in the AMS Datasource to show them on the Kafka-Topics dashboard. This means that if whitelisting is used the kafka.log.Log.* metrics must be enabled and must not be excluded by 'external.kafka.metrics.exclude.prefix' Kafka property either.
However, in some cases the large amount of kafka.log.Log.* metrics can be a burden to AMS, so excluding them would be welcomed.
The possibility to discover the Kafka topics should be assessed!
