Question

我无法使用bin / kafka-run-class.sh kafka.tools.JmxTool脚本获取JMX指标。但是，我可以使用Jconsole连接到进程。

我设置了以下属性：

com.sun.management.jmxremote = true
com.sun.management.jmxremote.authenticate = false
com.sun.management.jmxremote.local.only = false
com.sun.management.jmxremote.port = 9145
com.sun.management.jmxremote.ssl = false

例外：

? kafka_2.11-2.1.0/bin/kafka-run-class.sh kafka.tools.JmxTool --jmx-url service:jmx:rmi:///jndi/rmi://kafkatest-01:9154/jmxrmi

Trying to connect to JMX url: service:jmx:rmi:///jndi/rmi://kafkatest-01:9154/jmxrmi.

但是您的端口是9145

com.sun.management.jmxremote.port = 9145

想知道正在运行的JVM上实际上设置了哪些属性（用于检查类似这样的东西）

prompt> jcmd $pid VM.system_properties
