Prometheus之监控kafka集群

	1.启动kafka集群
[root@elk91 ~]# kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties 

[root@elk92 ~]# kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties 

[root@elk93 ~]# kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties 

	2.验证kafka服务是否正常
[root@elk91 ~]# zkCli.sh ls /zqylinux-kafka371/brokers/ids  | grep "^\["
[91, 92, 93]
[root@elk91 ~]# 

	3.下载kafka的exporter
wget https://github.com/danielqsj/kafka_exporter/releases/download/v1.7.0/kafka_exporter-1.7.0.linux-amd64.tar.gz


	4.启动kafka的exporter
[root@elk91 ~]# tar xf  kafka_exporter-1.7.0.linux-amd64.tar.gz -C /usr/local/bin/ kafka_exporter-1.7.0.linux-amd64/kafka_exporter  --strip-components=1
[root@elk91 ~]# 
[root@elk91 ~]# ll /usr/local/bin/
total 18876
drwxr-xr-x  2 root root     4096 Aug 16 11:03 ./
drwxr-xr-x 10 root root     4096 Aug 10  2023 ../
-rwxr-xr-x  1 1001  123 19317972 May 24  2023 kafka_exporter*
[root@elk91 ~]# 
[root@elk91 ~]# kafka_exporter --web.listen-address=":9308" --web.telemetry-path="/metrics"  --kafka.version="3.7.1" --kafka.server=10.0.0.93:9092


	5.访问测试kafka的exporter页面
http://10.0.0.91:9308/metrics


	6.Prometheus配置监控kafka的exporter
[root@prometheus-server31 ~]# vim /zqylinux/softwares/prometheus-2.53.2.linux-amd64/prometheus.yml 
...
  - job_name: zqylinux-kafka
    static_configs:
    - targets:
      - 10.0.0.91:9308

[root@prometheus-server31 ~]# 
[root@prometheus-server31 ~]# check 
Checking /zqylinux/softwares/prometheus-2.53.2.linux-amd64/prometheus.yml
SUCCESS: /zqylinux/softwares/prometheus-2.53.2.linux-amd64/prometheus.yml is valid prometheus config file syntax

[root@prometheus-server31 ~]# 
[root@prometheus-server31 ~]# rr

	7.查看Prometheus的WebUI是否监控到目标
http://10.0.0.31:9090/targets

	8.grafana出图展示，id为12460

	9.测试验证准确
		9.1 创建topic
[root@elk93 ~]# kafka-topics.sh --bootstrap-server 10.0.0.91:9092 --create --topic xixi --partitions 3 
Created topic xixi.
[root@elk93 ~]# 

		
		9.2 启动消费者
[root@elk92 ~]# kafka-console-consumer.sh --bootstrap-server 10.0.0.91:9092  --topic xixi 

		9.3 启动生产者
[root@elk93 ~]# kafka-console-producer.sh --bootstrap-server 10.0.0.91:9092  --topic xixi
