Quick Start

Fastest Path to Running Collector

# Install Task (build automation tool)
brew install go-task/tap/go-task  # macOS
# or: sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b ~/.local/bin  # Linux

# Clone and setup
git clone https://github.com/database-intelligence-mvp
cd database-intelligence-mvp

# Configure environment
cp .env.example .env
# Edit .env with your database credentials and New Relic license key

# Start everything
task quickstart

This single command will:

• Install dependencies
• Fix common setup issues
• Build the collector
• Start PostgreSQL and MySQL containers
• Begin collecting and sending metrics to New Relic

For Different Audiences

For Operators: Start with DEPLOYMENT.md for production deployment options using Docker, Kubernetes/Helm, or binaries.

For Developers: Start with DEVELOPER_GUIDE.md for comprehensive development workflow, then see TECHNICAL_IMPLEMENTATION_DEEPDIVE.md for code architecture details.

For Architects: Review ARCHITECTURE.md for system design and UNIFIED_IMPLEMENTATION_OVERVIEW.md for comprehensive analysis.

For Configuration: See CONFIGURATION.md for detailed configuration options and environment overlays.

Testing the Collector

This project includes a comprehensive testing suite to ensure quality and reliability.

• Unit Tests: For individual components.
• Integration Tests: For interaction with live databases.
• End-to-End (E2E) Tests: For validating the entire pipeline against New Relic.

For detailed instructions on how to run these tests, please see the Testing Guide.
