日常运维 、问题排查 怎么能够少了滴滴开源的滴滴开源LogiKM一站式Kafka监控与管控平台

1.删除指定分区的消息kafka-delete-records.sh

删除指定topic的某个分区的消息删除至offset为1024

先配置json文件offset-json-file.json

{"partitions":
[{"topic": "test1", "partition": 0,
  "offset": 1024}],
  "version":1
}

在执行命令

sh bin/kafka-delete-records.sh --bootstrap-server 172.23.250.249:9090 --offset-json-file config/offset-json-file.json

验证通过 LogIKM 查看发送的消息

从这里可以看出来,配置"offset": 1024 的意思是从最开始的地方删除消息到 1024的offset; 是从最前面开始删除的

2. 查看Broker磁盘信息kafka-log-dirs.sh

查询指定topic磁盘信息--topic-list topic1,topic2

sh bin/kafka-log-dirs.sh --bootstrap-server xxxx:9090 --describe --topic-list test2

查询指定Broker磁盘信息--broker-list 0 broker1,broker2

sh bin/kafka-log-dirs.sh --bootstrap-server xxxxx:9090 --describe --topic-list test2 --broker-list 0

例如我一个3分区3副本的Topic的查出来的信息 logDir Broker中配置的log.dir

{
	"version": 1,
	"brokers": [{
		"broker": 0,
		"logDirs": [{
			"logDir": "/Users/xxxx/work/IdeaPj/ss/kafka/kafka-logs-0",
			"error": null,
			"partitions": [{
				"partition": "test2-1",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-0",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-2",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}]
		}]
	}, {
		"broker": 1,
		"logDirs": [{
			"logDir": "/Users/xxxx/work/IdeaPj/ss/kafka/kafka-logs-1",
			"error": null,
			"partitions": [{
				"partition": "test2-1",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-0",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-2",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}]
		}]
	}, {
		"broker": 2,
		"logDirs": [{
			"logDir": "/Users/xxxx/work/IdeaPj/ss/kafka/kafka-logs-2",
			"error": null,
			"partitions": [{
				"partition": "test2-1",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-0",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}, {
				"partition": "test2-2",
				"size": 0,
				"offsetLag": 0,
				"isFuture": false
			}]
		}]
	}, {
		"broker": 3,
		"logDirs": [{
			"logDir": "/Users/xxxx/work/IdeaPj/ss/kafka/kafka-logs-3",
			"error": null,
			"partitions": []
		}]
	}]
}

如果你觉得通过命令查询磁盘信息比较麻烦，你也可以通过 LogIKM 查看
