下载Prometheus:
https://github.com/prometheus/prometheus/releases/download/v2.8.1/prometheus-2.8.1.linux-amd64.tar.gz

下载Kafka_exporter:
https://github.com/danielqsj/kafka_exporter/releases/download/v1.2.0/kafka_exporter-1.2.0.linux-amd64.tar.gz

下载Grafana:
https://grafana.com/grafana/download

  1. 要在你想监控kafka的机器上装上kafka_exporter,每个都要装,我的机器是157、158、187:

解压kafka_exporter,进到目录,执行命令:
nohup ./kafka_exporter --kafka.server=10.131.178.157:9092 &
没有报错就成功了!

  1. 在要显示页面的机器上安装Prometheus,我的机器是186:

解压Prometheus,进入目录,
vim prometheus.yml(具体修改见下图)
nohup ./prometheus &
启动成功后在浏览器输入10.131.178.186:9090,成功效果图见下:

  1. 在186机器上安装Grafana,下载解压后进去bin目录下:

nohup ./grafana-server &

  1. 打开浏览器,输入10.131.178.186:3000,就会显示页面:

  2. 配置Grafana数据源,见下图:

  3. 导入Kafka数据模板Kafka Dashboard:

  4. 成功截图,不截了,测试机器就一个图表有数据!

更多问题详见我博客的其他文章!!!

图废了!!!
