AKHQ is a GUI for Apache Kafka that lets you manage topics, topics data, consumer groups and more. Some of our teams have found AKHQ to be an effective tool to watch the real-time status of a Kafka cluster. You can, for example, browse the topics on a cluster. For each topic, you can visualize the name, the number of messages stored, the disk size used, the time of the last record, the number of partitions, the replication factor with the in-sync quantity and the consumer group. With options for Avro and Protobuf deserialization, AKHQ can help you understand the flow of data in your Kafka environment.
