Hi Jayesh,
Are you using Ambari 2.0 with Ambari Metrics service?

After the install, I was able to get metrics for both Storm and Kafka via REST API. This worked fine for a week, but since the past 2 days, I have not been getting Kafka metrics. I need the metrics to push to an OpenTSDB cluster. I do get host metrics and Nimbus metrics but not KAFKA_BROKER metrics. I did have maintenance turned on for some time, but maintenance is turned off now.
