BSc Dissertation Project - University of Manchester - JNI Exception Capturing Agent for Production Debugging

CMake on a single platform LaTeX Build

Overview

This repository contains the implementation of a C JNI Agent designed to recursively capture the values of objects within methods on a stack trace.

Prerequisites

To utilize this agent, you need to install the following libraries:

  • libxml2
  • crypto
  • openssl

Installation and Usage

  1. Building the JNI Agent: Compile the JNI agent and generate the library files.

  2. Running with Java: Incorporate the resulting library files using the -agentpath flag in the Java command.

Scala Spray Server Integration

This agent interfaces with a basic Scala Spray server to record captured values in MongoDB.

Configuration

  • Modify the src/main/resources/application.conf file to configure the server settings.
  • Build and run the server using sbt run.

FuelPHP Dashboard

A FuelPHP dashboard is used to display the analysis results by communicating with the Scala Spray server.

Setup

  • Perform composer install to set up the FuelPHP dashboard.

Note

This implementation serves as a Minimum Viable Product (MVP). It is not stable, secure, or optimized. However, relevant code snippets, especially those demonstrating communication with the JNI, can be extracted and used.
