//! # RustFS Observability
//!
//! provides tools for system and service monitoring
//!
//! ## Features
//!
//! This crate provides observability tools for RustFS:
//! - Logging with tracing
//! - Metrics collection
//! - Distributed tracing
//!
//! ## Usage
//!
//! ```no_run
//! use rustfs_obs::init_obs;
//!
//! # #[tokio::main]
//! # async fn main() {
//! #   let _guard = match init_obs(None).await {
//! #         Ok(g) => g,
//! #         Err(e) => {
//! #             panic!("Failed to initialize observability: {:?}", e);
//! #         }
//! #     };
//! #   // Application logic here
//! #   {
//! #       // Simulate some work
//! #       tokio::time::sleep(std::time::Duration::from_secs(2)).await;
//! #       println!("Application is running...");
//! #   }
//! #   // Guard will be dropped here, flushing telemetry data
//! # }
//! ```
//!
//! ## System Monitoring Migration
//!
//! The system monitoring functionality has been migrated to `rustfs-metrics`.
//! Use `rustfs_metrics::init_metrics_collectors()` for system metrics collection.
//!
//! ```ignore
//! use tokio_util::sync::CancellationToken;
//! use rustfs_metrics::init_metrics_collectors;
//!
//! let token = CancellationToken::new();
//! init_metrics_collectors(token.clone());
//! ```
