LoadGenerator (based on 'Train-Ticket' Microservice Systems): A New Version LoadGenerator for Microservice Systems

The Train-Ticket LoadGenerator is a dedicated tool designed to simulate traffic for the Train Ticket Booking System, which is based on a microservice architecture containing 41 microservices. This tool is primarily developed in Go, leveraging its performance and simplicity to effectively test and benchmark the system.

Behavior Logic Graph

The following graphs illustrate the behavior logic of the Train-Ticket Microservice System.

• The yellow nodes represent higher-level classes or components in the system.
• The arrows indicate the invocation relationships between these components.

These graphs provide a clear visualization of how different parts of the system interact and communicate with each other, offering insights into the overall architecture and dependencies.

Environment Setup and Deployment Guide

This guide provides the necessary steps to set up the environment and deploy the application.

Prerequisites

To get started, ensure you have the following installed and configured:

1. Goland IDE: Recommended for development with Go.
2. Go Modules: Run the following command to tidy up dependencies:

   go mod tidy

Deployment and Running the Application

To deploy and run the application, follow these steps:

1. Set the BASE_URL environment variable(Replace 'http://10.10.10.220:30080' with the corresponding address):

   $env:BASE_URL = "http://10.10.10.220:30080"

2. Start the application:

go run main.go


helm repo add loadgenerator https://lgu-se-internal.github.io/loadgenerator
helm repo update

helm upgrade loadgen loadgenerator -n experiment --set baseURL=http://10.10.10.220:30081 --set config.threads=1

That's it! The application should now be running and accessible at the specified BASE_URL.
