Tracing Logger Config

tracing_logger_config is a Rust crate designed to simplify logging configuration and tracing setup using OpenTelemetry and the tracing crate. It provides an easy-to-use interface for managing log files, controlling log rotation, and setting up distributed tracing with optional Jaeger backend support.

Features

• Flexible Logging Configuration: Easily configure log paths, error log paths, log rotation strategies, and logging levels.
• Tracing Initialization: Set up tracing with OpenTelemetry, including optional support for a Jaeger backend.
• Log Rotation: Supports various log rotation strategies: never, minutely, hourly, and daily.
• Serde Integration: Configuration structs are serializable and deserializable using Serde, making integration with configuration files straightforward.

Installation

To use tracing_logger_config in your project, add it to your Cargo.toml:

[dependencies]
tracing_logger_config = "0.1.2"

Usage

Basic Configuration

Here's how to configure logging and tracing in your application:

use tracing_logger_config::{Config, init_tracing, RotationKind, LevelInner, ExporterEndpoint};

fn main() -> anyhow::Result<()> {
    let config = Config {
        log_path: Some("logs/app.log".into()),
        log_error_path: Some("logs/error.log".into()),
        rotation: RotationKind::Daily,
        level: Some(LevelInner::Info),
        exporter_endpoint: Some(ExporterEndpoint {
            host: "localhost".to_string(),
            port: 6831,
        }),
    };

    let _guard = init_tracing(config.exporter_endpoint.as_ref(), Some(&config))?;

    // Your application code here

    Ok(())
}

Configuration Details

The Config struct is used to specify logging and tracing settings. It allows you to set:

• Paths for log files and error logs
• Log rotation strategies (e.g., never, minutely, hourly, daily)
• Logging levels (e.g., trace, debug, info, warn, error)
• Optional endpoint for exporting tracing data

Tracing Initialization

The init_tracing function sets up tracing with OpenTelemetry, including optional Jaeger backend support:

use tracing_logger_config::{init_tracing, Config, ExporterEndpoint};

fn setup_tracing() -> anyhow::Result<()> {
    let exporter_endpoint = ExporterEndpoint {
        host: "localhost".to_string(),
        port: 6831,
    };

    let config = Config {
        log_path: Some("logs/app.log".into()),
        level: Some(LevelInner::Debug),
        ..Default::default()
    };

    let _guard = init_tracing(Some(&exporter_endpoint), Some(&config))?;

    // Tracing is now initialized

    Ok(())
}
