Ferrox Logger (ferrox-logger)

ferrox-logger sets up production-ready, structured JSON logging and Sentry telemetry for Ferrox applications. Built on top of tracing-subscriber and sentry, it provides unified log formatting, environmental level filtering, and automated crash reports.

Architectural Context

Containerized environments (Kubernetes, AWS ECS, Docker) require logs to be emitted in structured JSON format via stdout for centralized aggregation (Elasticsearch, Datadog, Loki). ferrox-logger ensures all log events retain trace IDs, timestamps, and module metadata.

Key Features

• 📝 Structured JSON Output: Standardized log format with timestamp, severity level, target module, and dynamic fields.
• 🚨 Sentry Integration: Automatic reporting of critical error events to Sentry APM.
• 🎛️ Environment-Driven Filtering: Configurable log level thresholds via RUST_LOG environment variables.

Example Usage

use ferrox_logger::{setup_logger, LoggerConfig};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let _sentry_guard = setup_logger(LoggerConfig::default())?;
    tracing::info!("Application booted successfully");
    Ok(())
}
