----------------------------------
Summary: Monitoring number of messages expired due to retention
policy
Key: KAFKA-6660
URL: https://issues.apache.org/jira/browse/KAFKA-6660
Project: Kafka
Issue Type: Improvement
Reporter: Matt Garbis
I have not been able to find this out, but is there a way to monitor how many
messages were expired based on the retention policy? If not, JMX metrics like
this would be very useful for my team. I would like to be able to filter this
by topic and broker. Something like:
{code:java}
kafka.server:type=BrokerTopicMetrics,name=MessagesExpiredPerSec{code}
Additionally taking this one step further, it would be cool to be able to
monitor how many messages a consumer group did not consume before they were
expired.
