Subject Re: Kafka broker metrics not appearing in REST API
Date Thu, 07 May 2015 03:07:11 GMT
Hi Siddharth,
Yes, I am using Ambari 2.0 with Ambari Metrics service.The interesting thing is that I got
them for some time and not anymore.And I also know that the metrics are being collected since
i can see them on the dashboard.Any pointer for troubleshooting?
And btw, it would be nice to have a count of messages received and not a computed metric count
/ min.TSDB does a good job of giving me cumulative and rate-per-sec graphs and numbers.
Thanks in advance,Jayesh

Subject: Kafka broker metrics not appearing in REST API Hi,
I have installed 2 clusters with Ambari and Storm and Kafka.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.
