Ricardo Bartolome created KAFKA-6358:
----------------------------------------
Summary: Per topic producer/fetch_consumer/fetch_follower metrics
Key: KAFKA-6358
URL: https://issues.apache.org/jira/browse/KAFKA-6358
Project: Kafka
Issue Type: Wish
Components: metrics
Affects Versions: 1.0.0
Reporter: Ricardo Bartolome
Priority: Minor
We are using the following JMX beans to monitor Kafka 1.0.0:
{code}
kafka.network:type=RequestMetrics,name=TotalTimeMs,request=Produce
Mean
50thPercentile
...
99thPercentile
kafka.network:type=RequestMetrics,name=RequestsPerSec,request=FetchConsumer
Count
kafka.network:type=RequestMetrics,name=RequestsPerSec,request=FetchFollower
Count
{code}
There are more, but this provide an idea of what we are using in order to get
produce/fetch operations on a per-broker basis. Nevertheless, in order to
identify abusing consumers/clients in our kafka cluster, we would appreciate to
have these metrics in a per-topic basis.
As example of per-topic metrics we have:
{code}
kafka.server:type=BrokerTopicMetrics,name=BytesOutPerSec,topic=.*
{code}
Where we have a per-topic bean with a "Count" attribute that we can query. That
way we can know which topics are ingesting more data and which ones less data.
We can't do that with the metric explained above.
Would you consider a change in an upcoming Kafka version as a feature request?
