Issue
I've read Visual VM remotely over ssh but I think I've not fully understood because it was not working for me :-( Please can someone give some example?
ssh -D 9696 [email protected]
and visualvm.exe -J-Dnetbeans.system_socks_proxy=localhost:9696 -J-Djava.net.useSystemProxies=true
starts visualvm, but no processes of external machine are shown (only the local ones like visualvm itself). Moreover sometimes (but not always) I got the message "channel 3: open failed: connect failed: Connection refused" in my ssh window.
Any help?
Solution
You either need to run jstatd on the remote side, or specify a JMX connection using host:port.
Jstatd:
jstatd -J-Djava.security.policy=permissions.txt [-p port]
After that: add a remote connection to the target machine, and on the properties of that remote connection configure the jstatd connection.
(permissions.txt contains for example this:
grant {
permission java.security.AllPermission;
};
Edit: (Answer to comment)
ssh -D 9696 me@remote
, and run jstatd as above on the remote command line. If you want jstatd to be on a different port than the default 1099, use the -p argument to jstatd.run
visualvm.exe -J-Dnetbeans.system_socks_proxy=localhost:9696 -J-Djava.net.useSystemProxies=true
on the local machinein visual vm: add new remote connection, and specify remote as host and the port for jstatd (1099 for default, or what you specified with -p when running jstatd)
You should now see the processes on the remote side in visualvm
