Monitoring questions.

[Vadim Keylis <vk...@gmail.com>]

Good afternoon. I have a few questions about kafka monitoring.

1. In the kafka monitoring section (
http://kafka.apache.org/documentation.html#monitoring)
<http://kafka.apache.org/documentation.html#monitoring>"kafka.server":name="UnderReplicatedPartitions",
type="ReplicaManager" sets normal value to be as 0. I check jmx and my
value is set to 1. I am pretty sure I set replication factor to be as 1.
       /usr/local/kafka/bin/kafka-list-topic.sh --zookeeper
zoo01.tagged.com:2181/kafka
topic: meetme   partition: 0    leader: 1       replicas: 2,1,3 isr: 1,3

       Would you please advise?

2. How programmatically know that partition has come up online and caught
up on replication after kafka service has been started.

Thanks,
Vadim

1. It seems that you have 3 replicas and only 2 of them are caught up. Is
broker 2 still alive?

2. We have jmx beans that measure the lag per follower replica. Updated
http://kafka.apache.org/documentation.html#monitoring with this info.

Thanks,

Jun
