kafka查看消费了多少条数据

Posted 2023-03-04

参考技术A 如何查看目前的消费者是否已经读到最新的数据：

kafka-run-class.sh kafka.tools.ConsumerOffsetChecker
#kafka查看topic各个分区的消息的信息
kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --group ** --topic *** --zookeeper *:2181,*:2181,*:2181/kafka
--zookeeper 那里是指kafka在zk中的path,即使zk有多个机器，如果在其中一台上执行此命令，显示连接不上，只写那台机器的地址端口+kafka的path即可
指定自己的分组 自己消费的topic会显示kafka总共有多少数据，以及已经被消费了多少条
结果：
GROUP TOPIC PID OFFSET LOGSIZE LAG
消费者组 话题id 分区id 当前已消费的条数 总条数 未消费的条数

注意：以kafkaspout类作为消费者去读kafka数据，相当于直接从kafka server上取文件，没有消费者组的概念
每次读的数据存在自己zk的offet中
所以不能通过上述命令查看本回答被提问者采纳
