Eclipse Jifa is open-source software for better troubleshooting common problems that occurred in Java applications.

Many of the useful tools are client-based. When faced with problems in the production environment or the cloud environment, such tools cannot be used directly due to network or resource problems. Jifa provides a web solution, allowing developers to use the browser to troubleshoot.

The following features are supported:

• Heap Dump Analysis

• GC Log Analysis

• Thread Dump Analysis

The backend of Jifa uses Vert.x as the main framework and consists of two modules:

• Master
  • manage workers and route the requests from browser to the workers
• Worker
  • do the real analysis work

The frontend of Jifa uses Vue as the main framework.

• Prerequisites

  • JDK 11+, and make sure $JAVA_HOME is set properly

  • npm

• Build All

  $ ./gradlew buildJifa

• Build Worker Only

  $ ./gradlew buildWorker

• Master & Worker

  • Default pattern

    $ ./deploy_jifa.sh

  • K8S pattern, workers are scheduled by K8S

• Worker Only

  $ cd deploy
  $ ./depoy_worker.sh
