How to perform memory analysis on remote Java Web Applications

I know we can use tools like jpprofiler

Any ideas?

Solution

You have visualgc, which is not very advanced, but you can see the memory usage of your application (garbage, old, perm... Etc.)

http://java.sun.com/performance/jvmstat/visualgc.html

Recovery: you started daemon monitoring on the remote computer（ http://java.sun.com/j2se/1.5.0/docs/tooldocs/share/jstatd.html , see security parameters)

JAVA_HOME/bin/jstatd -J-Djava.security.policy=jstatd.all.policy

Here is a file called jstatd all. Policy file, which contains:

grant codebase "file:${java.home}/../lib/tools.jar" {   
permission java.security.AllPermission;
};

On a remote computer, you can use the JPS tool to debug the PID of the application:

http://java.sun.com/j2se/1.5.0/docs/tooldocs/share/jps.html#jps

Finally, on your local machine, you started visualgc:

visualgc the_pid@remote_machine_address
