[英]How to find the JMX port in a server?
I am sure I can figure it out if I can see the JAVA OPTS parameters. 如果我能看到JAVA OPTS参数,我相信我能搞清楚。 I want to monitor a hornetq server using Jconsole, so I need the port number.
我想使用Jconsole监视一个hornetq服务器,所以我需要端口号。
I remember using some command like java grep etc when I connected to it a while back. 我记得在我连接它的时候使用了一些像java grep等命令。
I know it's an old post. 我知道这是一个老帖子。 You can also get the details from System:
您还可以从系统中获取详细信息:
String jmx1 = System.getProperty("com.sun.management.jmxremote");
String jmx2 = System.getProperty("com.sun.management.jmxremote.port");
String jmx3 = System.getProperty("com.sun.management.jmxremote.authenticate");
String jmx4 = System.getProperty("com.sun.management.jmxremote.ssl");
String jmx5 = System.getProperty("java.rmi.server.hostname");
You can also manually set the port from the JVM commandline settings, eg: 您还可以从JVM命令行设置手动设置端口,例如:
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.port=1616
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
You can programmatically access the JVM arguments like so : 您可以以编程方式访问JVM参数,如下所示 :
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
...
RuntimeMXBean RuntimemxBean = ManagementFactory.getRuntimeMXBean();
List<String> arguments = RuntimemxBean.getInputArguments();
