使用jmx_exporter对kafka进行监控
Use jmx_exporter to collect Kafka metrics
导入jmx_prometheus_javaagent-0.18.0.jar和config.yml
Use jmx_prometheus_javaagent-0.18.0.jar and edit config.yml
windows启动kafka-javaagent startwithagent.bat的启动脚本
Edit kafka-javaagent startwithagent.bat for Windows system to start kafka, Such as:
SET KAFKA_HOME=E:\kafka_2.12-2.8.1
SET KAFKA_OPTS=-javaagent:%KAFKA_HOME%\jmx_prometheus_javaagent-0.18.0.jar=6660:%KAFKA_HOME%\config.yml
cd %KAFKA_HOME%\bin\windows
kafka-server-start.bat %KAFKA_HOME%\config\server.properties
PowerShell
