java - 怎么在本机监控远程服务器上的JVM堆栈使用空间，GC详情，CPU，内存等参数？

Question

我本机安装了VisualVM，可以监控本机的Java应用。但是不清楚怎么配置参数去监考服务器的Java应用。

Answer 1

Modify the remote machine JRE configuration file:

1. Enter the $JAVA_HOMEjrelibmanagement directory
2. Rename jmxremote.password.template to jmxremote.password
3. Open jmxremote.password and remove the comments of monitorRole QED and controlRole R&D
4. Modify the configuration file of the monitored program, such as tomcat : Open $TOMCAT_HOMEbincatalina.sh and add

at the bottom of the comment

JAVA_OPTS="$JAVA_OPTS -Djava.rmi.server.hostname=这里是服务器IP
                      -Dcom.sun.management.jmxremote.port=1099自定义一个端口
                      -Dcom.sun.management.jmxremote.ssl=false 
                       Dcom.sun.management.jmxremote.authenticate=false"

5. Open VisualMV, click Remote, enter the server IP as the host name, click advanced settings to set the port, right-click the IP you just configured, select the JMX connection method, enter the port again after the IP, and click OK. .

Answer 2

Are you unable to connect to the remote server locally?
