Log Watcher (Similar to tail -f)

Overview

This Log Watcher project implements a real-time log monitoring solution, similar to the UNIX tail -f command. It consists of a server-side program that monitors a log file on a remote machine and a web-based client that displays updates in real-time.

Features

• Real-time Monitoring: Server-side program to stream updates from the log file.
• Web-based Client: A client interface that shows live updates without page refresh, displaying the last 10 lines of the log.
• Performance Optimized: Efficient handling of large log files.
• Multi-client Support: The server can handle multiple clients simultaneously.
• No Page Reload: The web page updates in real-time without reloading.

Prerequisites

• Node.js environment.
• protobuf-compiler for protobuf support.
