kafka運維常用命令
列出所有的topic./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --list
檢視 topic資訊
./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --describe --topic topicname
./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --describe --topic __consumer_offsets
./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --describe --topic kafka_demo_test_topic
檢視所有的group
./bin/kafka-consumer-groups.sh --bootstrap-server 127.0.0.1:9092 localhost:2181 --list
檢視消費情況
./bin/kafka-consumer-groups.sh --bootstrap-server 127.0.0.1:9092 --describe --group kafkademo_test_group
kafka-consumer-groups.sh
老版本 消費元資料存在zk上 使用 --zookeeper localhost:2181
新版本 使用 --bootstrap-server 127.0.0.1:9092
./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --describe --topic kafka_demo_test_topic

current_offset 當前消費offset
log_eng_offset 最新的offset
lag 落後多少
增加分割槽數 只能加不能減
./bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --alter --partitions 8 --topic kafka_demo_test_topic
