1. Find the installation directory where kafka is located
find / -name kafka2. List which user groups are consuming:
./kafka-consumer-groups.sh --bootstrap-server 192.168.100.77:29092 --list#bootstrap-server Install the server address of kafka
3. Check the kafka message consumption of a certain user group and see if there is any data backlog
./kafka-consumer-groups.sh --bootstrap-server 192.168.100.77:9092 --describe --group groupname
#可用第二条命令查询用户组的ID
#执行后的效果
TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID
这是你的topic消息队列id 0 138 189 51 - - -
# CURRENT-OFFSET 这是当前已经消费了的偏移量
# LAG 这是消息积压数量groupname is one of the results of the first step of query
4. Check the maximum value of the data offset (offset) of a certain partition of the topic, which is to see how many messages are currently in Kafka.
./kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list 192.168.100.77:9092 --topic globalLog-test --partitions 0
###结果
globalLog-test:0:338828
