Log Analyzer and Alerting System

This project implements a log analysis and alerting system written in Go. It reads log files, parses them according to a configurable format, and triggers alerts based on predefined rules.

Features

• Customizable log parsing using regular expressions.
• Flexible rule-based alerting.
• Supports multiple alerting methods (e.g., email, Slack).
• Concurrent processing for efficient log analysis.

Getting Started

1. Configuration: Modify config.json to specify the log file path, parsing rules, and alerting settings.
2. Build: go build
3. Run: ./loganalyzer
