How to Use Meteor for Real-Time Java App Diagnosis and Performance Tuning

Software Architecture

Main Framework: SpringBoot (version 2.1.5.RELEASE)

Frontend: Freemarker template engine

UI: ace (web template framework located in resources/static/ace)

Agent: Arthas (used for data collection)

Proxy: tunnelserver (proxy for user Agent data collection)

SSH: ganymed-ssh2 (SSH protocol for connecting to Linux servers)

Database: H2 (used by the Meteor console)

Quick Start

1. Execute meteor-console to package the application.

2. Run meteor-console-0.0.1-SNAPSHOT, which starts by default on port 8884.

3. Start the Arthas tunnel server with java -jar arthas-tunnel-server-xxx.jar &, which opens ports 7777 and 8080. You can change the default port, e.g.,

java -jar -Dserver.port=9999 arthas-tunnel-server-xxx.jar &

.

java -jar meteor-console-0.0.1-SNAPSHOT &

java -jar arthas-tunnel-server-xxx.jar &

Feature List

1. Query classes loaded in the JVM

2. Online code editing and deployment

3. Method monitoring

4. Thread management

5. Dashboard

Conclusion

Meteor provides powerful dynamic diagnostics; whether handling sudden online incidents or performing deep performance tuning, it offers precise, “surgical‑knife” support for locating issues in live Java applications.
