rustfs-audit

Audit Target Management System for RustFS

rustfs-audit is a comprehensive audit logging system designed for RustFS. It provides multi-target fan-out, hot reload capabilities, and rich observability features for distributed storage and event-driven systems.

Features

• Multi-Target Fan-Out: Dispatch audit logs to multiple targets (e.g., Webhook, MQTT) concurrently.
• Hot Reload: Dynamically reload configuration and update targets without downtime.
• Observability: Collect metrics such as EPS (Events Per Second), average latency, error rate, and target success rate.
• Performance Validation: Validate system performance against requirements and receive optimization recommendations.
• Extensible Registry: Manage audit targets with add, remove, enable, disable, and upsert operations.
• Global Singleton: Easy-to-use global audit system and logger.
• Async & Thread-Safe: Built on Tokio and Rust async primitives for high concurrency.

Getting Started

Add Dependency

Add to your Cargo.toml:

[dependencies]
rustfs-audit = "0.1"

Basic Usage

Initialize and Start Audit System

use rustfs_audit::{start_audit_system, AuditLogger};
use rustfs_ecstore::config::Config;

#[tokio::main]
async fn main() {
    let config = Config::load("path/to/config.toml").await.unwrap();
    start_audit_system(config).await.unwrap();
}

Log an Audit Entry

use rustfs_audit::{AuditEntry, AuditLogger, ApiDetails};
use chrono::Utc;
use rustfs_targets::EventName;

let entry = AuditEntry::new(
"v1".to_string(),
Some("deployment-123".to_string()),
Some("siteA".to_string()),
Utc::now(),
EventName::ObjectCreatedPut,
Some("type".to_string()),
"trigger".to_string(),
ApiDetails::default (),
);

AuditLogger::log(entry).await;

Observability & Metrics

use rustfs_audit::{get_metrics_report, validate_performance};

let report = get_metrics_report().await;
println!("{}", report.format());

let validation = validate_performance().await;
println!("{}", validation.format());

Configuration

Targets are configured via TOML files and environment variables. Supported target types:

• Webhook
• MQTT

Environment variables override file configuration. See docs.rs/rustfs-audit for details.

API Overview

• AuditSystem: Main system for managing targets and dispatching logs.
• AuditRegistry: Registry for audit targets.
• AuditEntry: Audit log entry structure.
• ApiDetails: API call details for audit logs.
• AuditLogger: Global logger singleton.
• AuditMetrics, AuditMetricsReport: Metrics and reporting.
• PerformanceValidation: Performance validation and recommendations.

Observability

• Metrics: EPS, average latency, error rate, target success rate, processed/failed events, config reloads, system starts.
• Validation: Checks if EPS ≥ 3000, latency ≤ 30ms, error rate ≤ 1%. Provides actionable recommendations.
