二进制Kafka集群接入JMX_Exporter以及Kafka_exporter监控

释放双眼,带上耳机,听听看~!

前面介绍过了Docker-compose以及Kubernetes做Kafka的监控,接下来我们使用传统的方式接入Kafka的监控。

首先需要下载jmx_exporter的包,引用到Kafka 启动文件中

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.19.0/jmx_prometheus_javaagent-0.19.0.jar

#永久下载地址
wget https://d.frps.cn/file/tools/kafka/jmx_prometheus_javaagent-0.19.0.jar

Jmx exporter中包含了kafka各个组件的指标,如server metrics、producer metrics、consumer metrics等,但这些指标并不是prometheus格式的,因此需要通过重命名方式转变为prometheus格式,重命名规则配置在kafka-2_0_0.yml中

wget https://github.com/prometheus/jmx_exporter/blob/main/example_configs/kafka-2_0_0.yml

#永久下载地址
wget  https://d.frps.cn/file/tools/kafka/kafka-2_0_0.yml

编辑Kafka-server-start.sh启动脚本

export KAFKA_OPTS="-javaagent:/opt/kafka/bin/jmx_prometheus_javaagent-0.19.0.jar=9700:/opt/kafka/bin/kafka-2_0_0.yml"

#jmx_exporter端口为9700
#agent jar包路径都放在了/opt/kafka/bin/下

启动服务

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

接下来访问9700端口就可以看到规则
