# Audit Log API

A comprehensive audit logging API system with multi-tenant support, designed to handle high-volume logging with advanced search and filtering capabilities.

## Features

- **Multi-tenant Architecture**: Complete data isolation between tenants
- **High Performance**: Handles 1000+ log entries per second
- **Advanced Search**: Full-text search using OpenSearch
- **Real-time Streaming**: WebSocket support for live log monitoring
- **Scalable Storage**: PostgreSQL with TimescaleDB for time-series optimization
- **Background Processing**: AWS SQS for asynchronous tasks
- **Security**: JWT authentication, role-based access control, data encryption
- **Export Functionality**: Export logs in JSON or CSV format
- **Data Retention**: Configurable retention policies with automatic cleanup

## Technology Stack

- **Framework**: Django 4.2 with Django REST Framework
- **Database**: PostgreSQL with TimescaleDB extension
- **Search**: OpenSearch
- **Message Queue**: AWS SQS
- **Cache**: Redis
- **Real-time**: Django Channels with WebSocket
- **API Gateway**: AWS API Gateway (configurable)

## Quick Start

### Prerequisites

- Python 3.9+
- Docker and Docker Compose
- AWS Account (for SQS)
- PostgreSQL 15+
- Redis 7+
- OpenSearch 2.11+

### Installation

1. Clone the repository:
```bash
git clone https://github.com/your-org/audit-log-api.git
cd audit-log-api
```

2. Copy environment variables:
```bash
cp .env.example .env
# Edit .env with your configuration
```

3. Start services with Docker Compose:
```bash
docker-compose up -d
```

4. Run migrations:
```bash
docker-compose exec web python manage.py migrate
```

5. Create superuser:
```bash
docker-compose exec web python manage.py createsuperuser
```

6. Start SQS worker:
```bash
docker-compose exec web python manage.py process_sqs_messages
```

## API Usage

### Authentication

```bash
# Login
curl -X POST http://localhost:8000/api/v1/auth/login/ \
  -H "Content-Type: application/json" \
  -d '{
    "username": "user",
    "password": "password",
    "tenant_slug": "test-company"
  }'

# Use the returned token in subsequent requests
export TOKEN="your-jwt-token"
```

### Create Audit Log

```bash
curl -X POST http://localhost:8000/api/v1/logs/ \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "action": "CREATE",
    "resource_type": "order",
    "resource_id": "12345",
    "severity": "INFO",
    "message": "Created new order",
    "metadata": {"amount": 100.00}
  }'
```

### Search Logs

```bash
# Search with filters
curl -X GET "http://localhost:8000/api/v1/logs/?action=CREATE&severity=INFO" \
  -H "Authorization: Bearer $TOKEN"

# Full-text search
curl -X GET "http://localhost:8000/api/v1/logs/?search=order" \
  -H "Authorization: Bearer $TOKEN"
```

### Real-time Streaming

```javascript
const ws = new WebSocket(`ws://localhost:8001/ws/logs/stream?token=${token}`);

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log('New audit log:', data);
};
```

### Export Logs

```bash
# Export as JSON
curl -X GET "http://localhost:8000/api/v1/logs/export/?format=json" \
  -H "Authorization: Bearer $TOKEN" \
  -o audit_logs.json

# Export as CSV
curl -X GET "http://localhost:8000/api/v1/logs/export/?format=csv" \
  -H "Authorization: Bearer $TOKEN" \
  -o audit_logs.csv
```

## Testing

Run the test suite:

```bash
# Run all tests
docker-compose exec web python manage.py test

# Run with coverage
docker-compose exec web coverage run --source='.' manage.py test
docker-compose exec web coverage report
```

## Performance Optimization

1. **Database Optimization**:
   - TimescaleDB automatically creates hypertables for time-series data
   - Indexes on frequently queried fields (tenant_id, timestamp, action)
   - Connection pooling configured for high concurrency

2. **Caching**:
   - Redis caching for statistics and frequently accessed data
   - 5-minute TTL for aggregate queries

3. **Asynchronous Processing**:
   - SQS for background indexing and archival
   - Bulk operations for improved throughput

4. **API Gateway**:
   - Rate limiting configured per user/tenant
   - Request/response compression
   - CDN integration for static content

## Security

- **Authentication**: JWT tokens with configurable expiration
- **Authorization**: Role-based access control (Admin, Auditor, User)
- **Data Encryption**: At rest and in transit
- **Input Validation**: Comprehensive request validation
- **Rate Limiting**: Prevents API abuse
- **Audit Trail**: Logs access to audit logs

## Deployment

### AWS Deployment

1. Set up RDS PostgreSQL with TimescaleDB
2. Create SQS queue
3. Deploy OpenSearch domain
4. Configure API Gateway
5. Deploy application using ECS/EKS or EC2
