Kafka Metrics for Messages Sent Per Second to Topic

Hi All, Which metric should be used when trying to get the number of messages which are being produced to a topic ? I tried this in Prometheus :sum(irate(kafka_server_brokertopicmetrics_messagesin_total{topic="my-topic"}[1m])) This works when I use a non-transactional producer. However, when I

Re: Kafka metrics to calculate number of messages in a topic

That will get you a good approximation, but it's not guaranteed to be completely accurate. Offsets in Kafka are not guaranteed to be continuous. For topics with log compaction enabled, the removed records will leave (potentially very large) holes in the offsets. Even for topics without log compac

I am not 100% sure what Burrow does, but I would assume that it compares committed offsets to end offsets (similar to `bin/kafka-consumer-group.sh`). This is a "global" view over all consumer in the group. Compare to the consumer metric, the might report a higher lag as it relies on consumer commit

Let's say a consumer wants to fetch 1000 bytes and there are two messages in the broker each of 600 bytes. The broker will give 1000 bytes to the consumer. The consumer will only be able to use the first 600 bytes since the remaining 400 bytes doesn't form a full message. 0.7 jmx are documented in

Is the data consumed more than once from different consumers? If that's not the case, byteout could be a bit larger than bytein since we could return a partial message to the consumer. The partial message will be ignored in the consumer though. Thanks, Jun On Tue, Apr 29, 2014 at 2:13 PM, Arnau
