1.jmx github地址

GitHub - prometheus/jmx_exporter: A process for exposing JMX Beans via HTTP for Prometheus consumption

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.16.1/jmx_prometheus_javaagent-0.16.1.jar

2.jmx config 

• 可以通过java.lang 采集机器cpu 内存等基础信息

• https://github.com/prometheus/jmx_exporter/tree/master/example_configs

cat <<"EOF" > common.yaml
---

3.自行下载安装好kafka和zk，这里不赘述 

4.修改zookeeper 启动脚本 

• 修改zookeeper 添加jmx_exporter.jar启动

• 在bin/zookeeper-server-start.sh 脚本EXTRA_ARGS 下面添加 EXTRA_ARGS

# 
# EXTRA_ARGS=${EXTRA_ARGS-'-name zookeeper -loggc'}

export EXTRA_ARGS="$EXTRA_ARGS -javaagent:/opt/app/jmx_exporter/jmx_prometheus_javaagent-0.16.0.jar=9142:/opt/app/jmx_exporter/common.yaml"
 

 

5.启动zk 

• 使用安装包中的脚本启动单节点 Zookeeper 实例：

bin/kafka-run-class.sh +289 CONSOLE_OUTPUT_FILE可能报找不到，赋个别的值就可以了
bin/zookeeper-server-start.sh -daemon config/zookeeper.properties

6.检查zk 

• zookeeper启动应该listen 2181和9142端口

• ss -ntlp |grep java 

 

7.修改kafka启动脚本， 添加jmx_exporter.jar启动 

• 在bin/kafka-server-start.sh 脚本最上面添加下面这行

• export KAFKA_OPTS="-javaagent:/opt/app/jmx_exporter/jmx_prometheus_javaagent-0.16.1.jar=9309:/opt/app/jmx_exporter/kafka-agent.yaml"

8.启动kafka 

• 使用 kafka-server-start.sh 启动 kafka 服务：

• bin/kafka-server-start.sh -daemon config/server.properties
