In order to maintain high availability, a healthy Kafka cluster requires a minimum number of ISRs for failover. A replica could be removed from the ISR pool for a couple of reasons: it is too far behind the leader’s offset (user-configurable by setting the replica.lag.max.messages configuration parameter), or it has not contacted the leader for some time (configurable with the replica.socket.timeout.ms parameter). No matter the reason, an increase in IsrShrinksPerSec without a corresponding increase in IsrExpandsPerSec shortly thereafter is cause for concern and requires user intervention.The Kafka documentation provides a wealth of information on the user-configurable parameters for brokers.",

下载Prometheus：

下载Kafka\_exporter:  
[https://github.com/danielqsj/kafka\_exporter/releases/download/v1.2.0/kafka\_exporter-1.2.0.linux-amd64.tar.gz][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][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！！！
