Note: There are two ways for VisualVM to connect to the remote server: JMX and jstatd. Neither method can perfectly support all functions.
For example, JMX does not support VisualGC,
jstatd does not support CPU monitoring,
can be configured at the same time and selected as needed for actual use.
jvisualvm program adds a remote connection, please turn off the local firewall.
JMX
1. Modify SpringBoot startup parameters
The normal springboot startup command is
nohup java -jar demo.jar &
After using monitoring:
nohup java -Djava.rmi.server.hostname=192.168.81.149 \ -Dcom.sun.management.jmxremote \ -Dcom.sun.management.jmxremote.port=1099 \ -Dcom.sun.management.jmxremote.authenticate=false \ -Dcom.sun.management.jmxremote.ssl=false \ -jar jvm-1.0-SNAPSHOT.jar &
java -Djava.rmi.server.hostname=192.168.81.149 \ -Dcom.sun.management.jmxremote \ -Dcom.sun.management.jmxremote.port=1099 \ -Dcom.sun.management.jmxremote.authenticate=false \ -Dcom.sun.management.jmxremote.ssl=false \ -jar jvm-1.0-SNAPSHOT.jar
jvm -1.0-SNAPSHOT.jar is the jar package of the project
192.168.81.149 is the machine ip where the project is deployed
1099 is the remote port number that jvisualvm needs to connect to
authenticate=false Not enabled, user authentication
2. Use local jvisualvm to monitor remote
vi jstatd.all.policyI specified the absolute path here to facilitate the elimination of path effects
grant codebase "file:${java.home}/../lib/tools.jar" { permission java.security.AllPermission; };Start the jstatd background application port (default is 1099) Use the parameter -p to specify other ports
jstatd -J-Djava.security.policy=jstatd.all.policy \ -J-Djava.rmi.server.hostname=192.168.81.149 \ -J-Djava.rmi.server.logCalls=true -p 1098(I ran the following command in the /usr/local/jdk1.8.0_161/bin path. There is a jstatd.all.policy file in this path. If you execute it elsewhere, remember Specify absolute or relative path) Among them,
-J-Djava.security.policy=jstatd.all.policy 指定路径 -J-Djava.rmi.server.logCalls=true 打印日志 -J-Djava.rmi.server.hostname=192.168.81.149 指定主机名,主机名应该和你用hostname -i命令执行出来的结果一致。Start the project
java -jar jvm-1.0-SNAPSHOT.jar2. Use local jvisualvm to monitor remote

Java is platform-independent because of its "write once, run everywhere" design philosophy, which relies on Java virtual machines (JVMs) and bytecode. 1) Java code is compiled into bytecode, interpreted by the JVM or compiled on the fly locally. 2) Pay attention to library dependencies, performance differences and environment configuration. 3) Using standard libraries, cross-platform testing and version management is the best practice to ensure platform independence.

To set up the JVM, you need to follow the following steps: 1) Download and install the JDK, 2) Set environment variables, 3) Verify the installation, 4) Set the IDE, 5) Test the runner program. Setting up a JVM is not just about making it work, it also involves optimizing memory allocation, garbage collection, performance tuning, and error handling to ensure optimal operation.
