houseme e44bece00d fix(audit): harden reload ordering, start race, paused drops, and batch observability (#4497)
Follow-up hardening for the audit control plane. The ABBA deadlock
(backlog#961), dispatch failure propagation (backlog#962), and credential
header redaction (backlog#963) already landed on main; this change addresses
the remaining audit-side findings.

- backlog#970: reload/commit now shuts down existing replay workers and closes
  old targets *before* activating the replacement set, so old and new workers
  never drain the same store concurrently and re-deliver entries. Extracted a
  state-neutral `shutdown_runtime_targets` helper (registry-then-cancellers
  lock order preserved).
- backlog#978: `start()` claims the `Starting` transition atomically under the
  state lock, closing the check-then-act race that could double-activate;
  `dispatch()` no longer returns Ok while paused, it surfaces an explicit
  `AuditError::Paused` so the audit trail is not silently corrupted.
- backlog#984 (audit part): `dispatch_audit_log` performs a single state read
  and interprets not-running/paused as a deliberate skip while surfacing real
  delivery failures; `dispatch_batch` records the same observability signals as
  single dispatch; documented the unordered cross-target fan-out.

Adds unit tests: paused dispatch returns Err, concurrent start does not hang or
double-activate, commit closes old targets before installing new, and
dispatch/dispatch_batch delivery-outcome coverage (all-fail -> Err, partial ->
Ok, all-success -> Ok).

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_config::server_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.
