For 2), do you have a topic with at least 2 replicas? Yes, all of our topics are configured with a replication factor of 3. Here's the output of --describe on one of them:
Topic:QProcTopic4 PartitionCount:16 ReplicationFactor:3 Configs: Topic: QProcTopic4 Partition: 0 Leader: 0 Replicas: 0,1,2 Isr: 0,1,2 Topic: QProcTopic4 Partition: 1 Leader: 1 Replicas: 1,2,0 Isr: 1,2,0 Topic: QProcTopic4 Partition: 2 Leader: 2 Replicas: 2,0,1 Isr: 2,0,1 Topic: QProcTopic4 Partition: 3 Leader: 0 Replicas: 0,2,1 Isr: 0,2,1 Topic: QProcTopic4 Partition: 4 Leader: 1 Replicas: 1,0,2 Isr: 1,0,2 Topic: QProcTopic4 Partition: 5 Leader: 2 Replicas: 2,1,0 Isr: 2,1,0 Topic: QProcTopic4 Partition: 6 Leader: 0 Replicas: 0,1,2 Isr: 0,1,2 Topic: QProcTopic4 Partition: 7 Leader: 1 Replicas: 1,2,0 Isr: 1,2,0 Topic: QProcTopic4 Partition: 8 Leader: 2 Replicas: 2,0,1 Isr: 2,0,1 Topic: QProcTopic4 Partition: 9 Leader: 0 Replicas: 0,2,1 Isr: 0,2,1 Topic: QProcTopic4 Partition: 10 Leader: 1 Replicas: 1,0,2 Isr: 1,0,2 Topic: QProcTopic4 Partition: 11 Leader: 2 Replicas: 2,1,0 Isr: 2,1,0 Topic: QProcTopic4 Partition: 12 Leader: 0 Replicas: 0,1,2 Isr: 0,1,2 Topic: QProcTopic4 Partition: 13 Leader: 1 Replicas: 1,2,0 Isr: 1,2,0 Topic: QProcTopic4 Partition: 14 Leader: 2 Replicas: 2,0,1 Isr: 2,0,1 Topic: QProcTopic4 Partition: 15 Leader: 0 Replicas: 0,2,1 Isr: 0,2,1 For 1), was the flush interval reached? Yes, I believe so. log.flush.interval is set to the default 10000. After passing 25K messages through the broker, I still do not see those mbeans. Thank you for your help with this. Let me know if there's any more information I can provide. We will be upgrading our clusters to 0.8.1.1 at some point this week. thanks, Robin On Mon, Apr 28, 2014 at 8:56 PM, Jun Rao <jun...@gmail.com> wrote: > For 2), do you have a topic with at least 2 replicas?
