JMX remote with jconsole via ssh tunneling with socks proxy:
1. Add this to JAVA_OPTS in remote process:
-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port={remoteJMXport} -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false 
2. ssh -D {proxyport} user@remotehost
3. jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort={proxyport} service:jmx:rmi:///jndi/rmi://{remotehost}:{remoteJMXport}/jmxrmi
