Kafka AWS deployment + UI console

We are going to deploy Kafka in Production and also monitor it via console. (e.g. State of partitions in Broker- leader and slaves, state of consumers ) Is there out-of-the-box solution? What is the best and efficient way of deployment and monitoring Has someone tried this- looks promising http:

Using MirrorMaker to move some data between clusters

Hi all, I have just a quick question. I was wondering if MirrorMaker is the right solution for this task, basically I need to move a subset of the data from a production cluster to a test cluster. My original idea was to set the log.retention.minutes to a low value like 12 hours so I could keep o

rate of producers writing to a topic?

Hi, Is there a way to monitor the rate of rates to a particular topic? I wish to monitor the frequency of incoming tuples in order to consume from the topic in particular ways depending on the incoming write throughput. Thanks, Josh

Re: migrating log data to new locations

I think the more automated/lazy way right now would be to shutdown one broker, rm -rf all its data, add the data directories in config, and restart to let the broker restore off the replicas. This may actually be okay though it is a little slower. -Jay On Tue, Oct 7, 2014 at 3:25 PM, Jun Rao wro

Re: migrating log data to new locations

You can stop the broker and copy some of the log directories to the new volumes. You have to be a bit careful when you do that. There are two metadata files recovery-point-offset-checkpoint and replication-offset-checkpoint that you have to manually split and copy over. Ideally, we should be able

Otis, Yes, if you guys can help provide a patch in a few days, we can probably get it to the 0.8.2 release. Thanks, Jun On Tue, Oct 7, 2014 at 12:10 PM, Otis Gospodnetic < otis.gospodne...@gmail.com> wrote: > Hi Jun, > > I think your MBean renaming approach will work. I see > https://issues.a

Re: MBeans, dashes, underscores, and KAFKA-1481

Hi Jun, I think your MBean renaming approach will work. I see https://issues.apache.org/jira/browse/KAFKA-1481 has Fix Version 0.8.2, but is not marked as a Blocker. We'd love to get the MBeans fixed so this makes it in 0.8.2 release. Do you know if this is on anyone's plate (the issue is curre

Re: migrating log data to new locations

Is it possible to perform this migration without losing the data currently stored in the kafka cluster? Though I haven't tested this, the way this is designed should allow you to shut down a broker, move some partition directories over to the new log volume and restart the broker. You will have to

migrating log data to new locations

Hi, I have a Kafka 0.8.1.1 cluster consisting in 4 servers with several topics on it. The cluster was initially configured to store kafka log data in a single directory on each server (log.dirs = /tmp/kafka-logs) Now, I have assigned 3 new disks to each server and I would like to use them to
