Tamas Payer updated AMBARI-25383:
---------------------------------
Description:
On Ambari 2.6.x and 2.7.x if the Ambari Metrics Collector whitelisting is
enabled, the Kafka Topics are not discovered on the Kafka topics dashboard.
(The Topics dropdown is empty.)
It can be remediated by adding '._p_kafka.log.Log.*' to the whitelist file and
restarting the Metrics Collector.
Adding the '._p_kafka.log.Log.*' to the whitelist file by default should be
considered. Also it should be investigated why we need the "._p_" prefix.
Furthermore, it seems that the metrics enabled in the whitelist file as:
{code:java}
kafka.server.BrokerTopicMetrics.BytesInPerSec.topic.*.count
kafka.server.BrokerTopicMetrics.BytesOutPerSec.topic.*.count
kafka.server.BrokerTopicMetrics.MessagesInPerSec.topic.*.count
kafka.server.BrokerTopicMetrics.TotalProduceRequestsPerSec.topic.*.count
{code}
are filtered out and not shown on Grafana dashboard.

On Ambari 2.6.2 if the Ambari Metrics Collector whitelisting is enabled, the
Kafka Topics are not discovered on the Kafka topics dashboard. (The Topics
dropdown is empty.)
