In this video:
1) Set up and SSH Tunnel with SOCKS proxy on Port 10,000
☐Open Putty. In Session, set Host Name as ec2-user@(public DNS).
Example: [email protected]
☐Go to Connection - SSH - Auth and under “Private key file for authentication” enter the path to the correct ppk file for the instance.
☐Under Connection - SSH - Tunnels, type 10000 into Source Port, select Dynamic, then Add. “D10000” should appear in Forwarded Ports. Select Open to open the tunnel.
☐To run code with JMX monitoring, Start the application with the following arguments added:
java -Dcom.sun.management.jmxremote.port=3333 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
YourJavaApp
(see https://docs.oracle.com/javase/7/docs/technotes/guides/visualvm/jmx_connections.html)
☐If necessary, include classpath and package, or
any other necessary arguments, as well. Example:
java -cp IntroToCompSci/homework/interfaces/QuizGenerator/src/main/java \
-Dcom.sun.management.jmxremote.port=3333 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false \
edu.yu.intro.interfaces.quizgenerator.QuizGenerator
(Slashes at the end of each line are added to allow a single command to be typed in the Bash across multiple lines, using the Enter key.)

2) Set Up VisualVM To Use SOCKS Proxy

☐In the VisualVM menu, select Tools - Options - Network.
Select Manual Proxy Settings and set
SOCKS PROXY as localhost, and the port as 10,000.

☐Make sure to uncheck Use the same proxy settings for all protocols.

3) Add Remote Host To VisualVM

☐Get the Private IP Address of the EC2 instance, viewable in the console.

☐In VisualVM, select File - Add Remote Host, enter the Private IP Address as the Host Name, and select OK.

☐Right click on the host and select Add JMX Connection.

☐Enter [Private IP Address]:[JMX Port]. In our case the port is 3333. Example: 172.31.16.181:3333

☐Select okay and wait for VisualVM to connect and begin profiling the currently running application
