GUI monitoring tools for JVMs __java-packaged, deployed

1.jconsole Tool JDK's bin/directory with the tools. The effect is shown in Figure 1-1.

The JDK's bin/directory has its own tools.

Heap dump can be used to parse programs, with a file suffix of. hprof.

The way to heap dump is shown in Figure 2-1

Open the visual VM to see directly. 2.2 Connecting remote JVM processes

The JVM's startup parameters need to be added on the remote machine.

For example, on a machine (Windows) to view the B machine (Linux) on the J process C (Java process) situation. You need to add parameters at C Startup:

-djava.rmi.server.hostname=${b Machine IP} 
-dcom.sun.management.jmxremote=true 
- Dcom.sun.management.jmxremote.port=${port} 
-dcom.sun.management.jmxremote.authenticate=false 
- Dcom.sun.management.jmxremote.ssl=false

Then put-jar (or-CP) These subsequent parameters on the back. JDK does not have to do any setup. See figure 2-2 after success.
