Hi, We have Ambari 2.5.0.3. I have been working on Kafka monitoring and I am trying to compare Ambari metric + Grafana with Kafka Manager from Yahoo. One the important metrics in Kafka is consumer goup lag. In Grafana dashboard "Kafka - topics", there is consumer lag graph. This graph is always empty when a topic is selected (no data). Does someone have this dashboard working as expected ? How to get consumer lag per consumer group for each topic in Ambari metric. Thank you

I found the root cause, ambari user which is created for oracle DB not have enough privileges to drop the Constraint. When I run ambari-server update the constraint is not dropping and not replacing new constraint.
