Log Analyzer

Overview

Parses and analyzes log files to extract errors, warnings, patterns, and actionable insights.

When to Use

• User asks to "analyze these logs" or "check the error log"
• Debugging session needs pattern analysis

How It Works

Step 1: Read log file

Windows: type server.log or Get-Content error.log -Tail 100 macOS/Linux: tail -n 100 app.log

Step 2: Detect log format

[2024-01-15 14:30:45] -> Timestamp bracketed ERROR 2024-01-15 -> Level + timestamp { "level": "error" } -> JSON structured

Step 3: Extract key information

Level: ERROR, WARN, INFO, DEBUG Timestamp: when it happened Source: which component/module Message: what happened

Step 4: Generate analysis report

Output Format

Total lines: 1,247 Time range: 10:00 -> 18:00

Errors: 23 Warnings: 67 Info: 892

Top Errors by frequency:

1. Connection timeout (x12) - API calls to external service
2. Auth failure (x6) - Failed login from IP xxx

Anomaly: Unusual spike at 16:00-17:00 (18 errors in 1 hour)

Recommendations:

1. Check external service connectivity
2. Review failed logins for security
3. Add retry logic to DB writes
