Audita

Audita is a modular auditing system that ensures data integrity and provides immutable audit trails for blockchain and cloud-native infrastructures.
Built in Rust with integrations to Prometheus, ElasticSearch, and Ethereum, it creates cryptographically secure records to guarantee system integrity and compliance.

🚀 Features

• ⚙️ High-performance Rust backend
• 📦 Containerized via Docker
• 📈 Prometheus & Grafana integration
• 🔍 Elasticsearch support for searchable logs
• ⛓️ Ethereum Besu-compatible pipeline
• 🧩 Modular architecture for easy extension

📦 Installation

Option 1: Docker (Recommended)

docker run ghcr.io/luizfelmach/audita:latest

Option 2: Build from Source

Prerequisites: Rust and Cargo installed.

git clone https://github.com/luizfelmach/audita.git
cd audita
cargo build --release
./target/release/audita

Option 3: Run via Precompiled Binary

1. Download the latest binary for your platform from the Releases page
2. Make it executable:

chmod +x audita
./audita

⚙️ Configuration

Audita can be configured through configuration files or environment variables. Configuration sources are loaded in the following order of precedence:

1. /etc/audita/config.toml (system-wide)
2. ~/.config/audita/config.toml (user-specific)
3. config.toml (current directory)
4. config/dev.toml (development config)
5. Environment variables (highest priority)

Configuration File Format

Create a config.toml file with the following structure:

host = "0.0.0.0"
name = "worker"
port = 8080
queue_size = 8192
batch_size = 5

[ethereum]
url = "http://localhost:8545"
contract = "0x42699A7612A82f1d9C36148af9C77354759b210b"
private_key = "0x8f2a55949038a9610f50fb23b5883af3b4ecb3c3bb792cbcefbd1542c692be63"
max_tx_pending = 50

[elastic]
url = "http://localhost:9200"
username = "elastic"
password = "changeme"
indices_pattern = "%Y.%m.%d"

Environment Variables

All configuration options can be overridden using environment variables with the AUDITA_ prefix. For nested configuration sections, use double underscores (__).

Examples:

export AUDITA_PORT=8080
export AUDITA_HOST="127.0.0.1"
export AUDITA_ETHEREUM__URL="http://localhost:8545"
export AUDITA_ETHEREUM__CONTRACT="0x42699A7612A82f1d9C36148af9C77354759b210b"
export AUDITA_ELASTIC__URL="http://localhost:9200"
export AUDITA_ELASTIC__USERNAME="elastic"
