Hi,
brokerPath is just optional.
Used if you want to have multile kafka clusters.
Each kafka cluster would connect to the same brokerPath.
Since I have multiple clusters I use the brokerPath.
From the looks of it you dont. So never mind it doesn't matter.
You only have one zookeeper correct ?
And kafka and flink connects to that only zookeeper ?

Hi Daniel,
Yes I have specified the zookeeper host in server.properties file , so
the broker is connected to zookeeper.
https://kafka.apache.org/documentation#brokerconfigs
<https://kafka.apache.org/documentation#brokerconfigs> -> according to
this link, I guess all these configs are done in server.prop , so from
where did you get kafka09 as brokerPath ?
this is my entry in server.prop file -> zookeeper.connect=localhost:2181
Have you set this as zkhost:2181/kafka09 ?

Hi,
Your kafka broker is connected to zookeeper I believe.
I am using kafka 0.9.0.1 my self too.
On kafka broker 0.9.0.1 I have configured the zookeeper connect to
a path, for instances :
zk1:2181,zk2:2181,zk3:2181/kafka09
https://kafka.apache.org/documentation#brokerconfigs
<https://kafka.apache.org/documentation#brokerconfigs>
Now on the flink side I would configure
"props.setProperty("zookeeper.connect", zkHosts)" the same
resulting in :
props.setProperty("zookeeperconnect",
"zk1:2181,zk2:2181,zk3:2181/kafka09")
That is what I mean by broker's path.

Hi Daniel,
I have the same properties set for the consumer and the same code
/brokerspath only needed if you have set it on kafka config/ -> I
did not get this, do you mean to check the brokerspath in
conf/server.properties file ? I have even tried by setting
offset.storage property to zookeeeper, but still not getting the
consumers listed
I am using Kafka 0.9.0.1

Hello,
This is my config.
On kafka props :
val props = new Properties()
props.setProperty("zookeeper.connect", zkHosts)
props.setProperty("bootstrap.servers", kafHosts)
props.setProperty("group.id <http://group.id>", "prod")
props.setProperty("auto.offset.reset", "earliest")
Now for zkHosts beware that all your hosts quorum has to be
included.
For instances you have zk1 and zk2 and zk3 to form a quorum.
Then it will result in zkHosts being ->
zk1:2181,zk2:2181,zk3:2181/[brokerspath] .
brokerspath only needed if you have set it on kafka config.
Ignore it otherwise, resulting in "zk1:2181,zk2:2181,zk3:2181" .
After that -> val source = env.addSource(new
FlinkKafkaConsumer09[String](KAFKA_TOPIC, new
SimpleStringSchema(), props))
Then on kafkamanager -> consumers I have the groupID prod.
Hope it helps.

Hi Limbo,
I am using 0.9, I am not able to see updated results even
after refreshing.
There is some property that we have to set in order to make
this work

I am using kafka 0.8, just refresh the page and you will
see the updated results, it’s not auto update.
There is our logstash consumer:
and this is our flink consumer:
I find the flink consumer just write the offset of the
kafka partition to zookeeper without owner and ids,
so we can’t find the consumer in the manager page, we
can only find the offset info.

Hi Limbo,
I can see the lag by using that URL, but the Lag there
is not showing updated results, it does not change,
also if you try to to change the consumer group value
it will still show you the same value instead of saying
consumer group does not exist or similar kind of error :)
According to documentation of 0.9.x the offsets are
stored in Kafka, but we can set offset.storage property
to zookeeper.
Even by setting this I am not getting the consumer listed.
Kafka cli command also does not show this consumer

Hi,
I have the same problem, I think the reason is that
the consumer of flink use the low level API,
and when I type the group name in manager url I can
get the lag of the flink consumer, like this:
http://your_manager_url/clusters/<kafka_name>/consumers/<consumer_name>/topic/<topic_name>/type/ZK
<http://your_manager_url/clusters/%3Ckafka_name%3E/consumers/%3Cconsumer_name%3E/topic/%3Ctopic_name%3E/type/ZK>

Hello,
I have been using that setup.
From my understanding, if one desires to see the
offset being consumed by Flink on KafkaManger, one
has to set it up with zookeeper. On 0.9 it will
only serve as a view of progress.
Basically what's mandatory on 0.8 is optional on
0.9, and for viewing purposes only.

Hi,
I am monitoring Kafka using KafkaManager for
checking offset lag and other Kafka metrics,
however I am not able to see the consumers
when I use FlinkKafkaConsumer , for
console-consumer it shows them in the
Consumers list.
I have set the required parameters for the
kafka consumer while running the application.
Has anyone faced this issue ?
I am using Kafka 0.9.0.1
