Timber 🪓

Timber: Fell Your Logs Fast - A lightning-fast CLI log analysis tool built in Rust.

📋 Overview

Timber is a log-agnostic CLI tool that chops through noise to deliver patterns, trends, and stats from your logs. It's designed to be portable, requiring no servers or complex setup, and works with logs from any source—Java, Rust, Python, or any text-based logs.

✨ Features

• Fast Pattern Search: Find matches with regex support
• Log Level Filtering: Focus on specific severity levels (ERROR, WARN, INFO, etc.)
• Time-based Trend Analysis: See how log patterns change over time
• Statistical Summaries: Get insights on log levels, error types, and message uniqueness
• Efficient Processing: Handles large log files with minimal resource usage
