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 infor

Answer 1

We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups.

$ rpm -qf /bin/kafka-consumer-groups
confluent-kafka-2.11-1.1.1-1.noarch

For example:

$ kafka-consumer-groups --describe --group logstash | grep -E "TOPIC|filebeat"
Note: This will not show information about old Zookeeper-based consumers.

Random Tip

NOTE: We use an alias that overloads kafka-consumer-groups like so in our /etc/profile.d/kafka.sh:

alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\"  kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"
