Kafka cluster configuration check

Question

Kafka comes with various .sh script to perform management activities on Kafka cluster such as topic creation, partition etc. But I am after .sh script which would allow me to inspect (discover) the active (in-force) configuration of building blocks such as broker, topic, partitions etc.

Is there any .sh script that is available which does this configuration inspection at runtime?

Note: I would like to view all configuration key/value entries (including default and overridden if any) for broker/topic/partition together or ideally separate.

Thanks in advance.

Answer 1

You can use topics.sh and describe the topic to get config detail related to the topic , the number of partition , replication factor , in sync replicas . Try

$ bin/kafka-topics.sh --describe --bootstrap-server localhost:9092 --topic my-topic

You will get something like:

Topic:my-topic   PartitionCount:1    ReplicationFactor:3 Configs:
    Topic: my-topic  Partition: 0    Leader: 1   Replicas: 1,2,0 Isr: 1,2,0

Answer 2

If I understand your question correctly then you are probably after something like the following

kafka-configs.sh $ZK --describe --entity-type topics This will provide the config for all topics. If no values exist for a topic then it means they are using the defaults (usually in server.properties ).

Instead of topics you can also use brokers , clients and users .
