Monitor remote host JVM memory usage using a VISUALVM with Java __java

The following is a simple procedure for configuring using the JXM protocol, and the details can be read in the reference material after the article.
1. Remote host

(1) Modify the configuration file for the JMX service:
In the JDK root directory/jre/lib/management, save Jmxremote.password.template as Jmxremote.password.
Use file editing software to remove Jmxremote.password by editing
# Monitorrole QED
# Controlrole R&d
Before the # Note, save.
If the current system belongs to AIX, Linux, or Solaris systems, you need to change jmxremote.access and Jmxremote.password permissions
To read only, commands are as follows
chmod jmxremote.access Jmxremote.password

(2) Modify the startup configuration information for the JVM:

Windows system
Set Java_opts=-dcom.sun.management.jmxremote.port=<port>-dcom.sun.management.jmxremote.ssl=false
-dcom.sun.management.jmxremote.authenticate=false-djava.rmi.server.hostname=-dcom.sun.management.jmxremote.ssl=false

AIX, Linux, or Solaris
Export java_opts= "-dcom.sun.management.jmxremote.port=<port>-dcom.sun.management.jmxremote.ssl=false
-dcom.sun.management.jmxremote.authenticate=false-djava.rmi.server.hostname=-dcom.sun.management.jmxremote.ssl=false "

For example:
Set Java_opts=-dcom.sun.management.jmxremote.port=1099-dcom.sun.management.jmxremote.ssl=false
-dcom.sun.management.jmxremote.authenticate=false-djava.rmi.server.hostname=192.168.1.24
-dcom.sun.management.jmxremote.ssl=false

The configuration is described as follows:
-dcom.sun.management.jmxremote.port the remote host port number.
-dcom.sun.management.jmxremote.ssl=false whether to use an SSL connection
-dcom.sun.management.jmxremote.authenticate=false whether to turn on remote service permissions
-djava.rmi.server.hostname remote host name, using IP address

(3) Restart the service.

2. Local Host Configuration

The

method starts the Jconsole command line tool by entering the <jdk_home>\bin directory one ,
. Add the transport computer information to the new connection in Jconsole.
For example: 192.168.1.24:1099 or service: JMX:RMI:///JNDI/RMI://192.168.1.24:1099&NBSP
<port>      Transport host Port  
Method Two ,
the version above JDK 1.6 contains a simple version of Jvisualvm.exe. Select Add remote host in the right mouse menu on remote, and enter the host name of the transport computer, which is actually the IP address of the remote computer to be detected. Right-click on the configured remote host to select Add JMX Connection ..., enter the remote host information according to the format required in method one.
