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.
