log4j configuration for zookeeper with kafka process

Hi All,

How to enable zookeeper logs for kafka process?

kafka provides "log4j.properties" property file which doesn't have
zookeeper entry.

Can someone please help me with log4j configuration to enable zookeeper
logs ?


Thank you.

Regards,
Mazhar Shaikh

Hi Patrick,

Thank you for you reply.

I'm actually trying to debug a issue with kafka broker, where kafka broker
losses the zookeeper session due to expiry.

[2016-09-06 05:00:42,595] INFO Client session timed out, have not heard
from server in 20903ms for sessionid 0x256fabec47c0003, closing socket
connection and attempting reconnect (org.apache.zookeeper.ClientCnxn)
[2016-09-06 05:00:42,696] INFO zookeeper state changed (Disconnected)
(org.I0Itec.zkclient.ZkClient)

To debug this, I feel both zookeeper server & zookeeper client logs may be
helpful.

Regards,
Mazhar Shaikh

Hi Mazhar, if you're interested in ZK client logs when running Kafka that's
a question better answered by the Kafka community, there are many ways to
set things up, it's likely controlled by the Kafka configuration.

Patrick
