What command shows all of the topics and offsets of partitions in Kafka?

Question

I'm looking for a Kafka command that shows all of the topics and offsets of partitions. If it's dynamically would be perfect. Right now I'm using java code to see these information, but it's very inconvenient.

Kafka ships with some tools you can use to accomplish this.

List topics:

# ./bin/kafka-topics.sh --list --zookeeper localhost:2181 test_topic_1 test_topic_2 ... 

List partitions and offsets:

# ./bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --broker-info --group test_group --topic test_topic --zookeeper localhost:2181 Group           Topic                  Pid Offset          logSize         Lag             Owner test_group      test_topic             0   698020          698021          1              test_group-0 test_group      test_topic             1   235699          235699          0               test_group-1 test_group      test_topic             2   117189          117189          0               test_group-2 

Update for 0.9 (and higher) consumer APIs

If you're using the new apis, there's a new tool you can use: kafka-consumer-groups.sh.

./bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group count_errors --describe GROUP                          TOPIC                          PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             OWNER count_errors                   logs                           2          2908278         2908278         0               consumer-1_/10.8.0.55 count_errors                   logs                           3          2907501         2907501         0               consumer-1_/10.8.0.43 count_errors                   logs                           4          2907541         2907541         0               consumer-1_/10.8.0.177 count_errors                   logs                           1          2907499         2907499         0               consumer-1_/10.8.0.115 count_errors                   logs                           0          2907469         2907469         0               consumer-1_/10.8.0.126
