smart-log-reader 1.0.0

Intelligent, extensible log reader and analyzer with color-coded output and smart error grouping.

🐍 smart-log-reader

Stop grep-ing blindly.
smart-log-reader is an intelligent, terminal-first log analyzer that instantly parses massive log files, groups similar errors using fuzzy matching, and outputs beautifully formatted, color-coded summaries directly in your terminal.

When the terminal isn't enough, export a fully interactive HTML dashboard and serve it securely from your remote server to your local machine via an SSH tunnel.

🚀 Installation

Because this is a standalone CLI tool, do not install it globally with pip.
Use pipx to install it in an isolated environment so it never conflicts with your system dependencies.

pipx install smart-log-reader

🔥 Quick Start: Real-World Scenarios

1. The "Server is on fire" check (Auto-detects format, groups errors)

smart-log-reader -f /var/log/syslog -l ERROR

2. The "Odoo is crashing" audit (Filter by time and keyword)

smart-log-reader -f odoo-server.log -t odoo -k "psycopg2" -s "2024-03-05 10:00:00"

3. Generate an interactive HTML report and serve it securely

smart-log-reader -f production.log -t python -x html --serve

✨ Core Features

• Format Auto-Detection
  Automatically recognizes Python, Django, Flask, Odoo, Nginx, Apache, PostgreSQL, MySQL, and JSON-line logs.

• Intelligent Error Grouping
  Uses rapidfuzz (85% threshold) to group thousands of repetitive tracebacks into unique "Core Issues", showing you exactly what broke and how often.

• Zero-Memory Streaming
  Processes multi-gigabyte log files line-by-line without eating up your server's RAM.

• Multi-line Unification
  Automatically stitches stack traces and JSON payloads back together into single, readable entries.

🛡️ The Killer Feature: Secure HTML Export & Tunneling

When debugging remote production servers, downloading gigabytes of logs is tedious and risky.
smart-log-reader solves this natively.

With --serve, it:

• generates a self-contained HTML dashboard
• starts a minimal, localhost-only HTTP server on the production machine
• lets you view it securely via SSH tunnel

Your log data never leaves the server.

How to use it

On the remote server:

smart-log-reader -f /var/log/nginx/error.log -x html --serve --port 8080

On your local machine:

ssh -L 8080:127.0.0.1:8080 [e-mail]

Then open in your browser:
http://localhost:8080/report_name.html

Alternative (LAN / VPN only): use --serve-public → gets a token-protected URL, no SSH tunnel needed.
