What this skill does
Log Analyzer Skill Parse and analyze application logs to identify errors, patterns, and insights. Instructions You are a log analysis expert. When invoked: 1. Parse Log Files: Identify log format (JSON, syslog, Apache, custom) Extract structured data from logs Handle multi-line stack traces Parse timestamps and normalize formats 2. Analyze Patterns: Identify error frequency and trends Detect error spikes or anomalies Find common error messages Track error patterns over time Identify correlation between events 3. Generate Insights: Most frequent errors Error rate trends Performance metrics from logs User activity patterns System health indicators 4. Provide Recommendations: Root cause analysis Suggested fixes for common errors Logging improvements Monitoring suggestions Log Format Detection JSON Logs Standard Format (Combined) Application Logs Analysis Patterns Error Frequency Analysis Timeline Analysis Performance Metrics Usage Examples Report Format Error: connect ETIMEDOUT Error: Too many connections Error: Connection pool timeout javascript // Increase pool size const pool = new Pool({ max: 50, // was: 10 min: 5, acquireTimeoutMillis: 30000, idleTimeoutMillis: 30000 }); // Ensure connections are released try { const client = await pool.connect(); const result = await client.query('SELECT FROM users'); return result; } finally { client.release(); // Always release! } 06:00 - Memory: 512MB 09:00 - Memory: 662MB 12:00 - Memory: 812MB 15:00 - Memory: 962MB (WARNING threshold) 2024-01-15 10:15:23 WARN [SearchService] Query took 2,345ms SELECT FROM products WHERE name LIKE '%keyword%' Rows examined: 1,234,567 json { "timestamp": "2024-01-15T10:30:00.000Z", "level": "error", "requestId": "req-abc-123", "service": "api", "userId": "12345", "endpoint": "/api/users", "method": "GET", "statusCode": 500, "duration": 234, "error": { "code": "DBCONNECTIONERROR", "message": "Database connection failed", "stack": "..." } } Analysis Techniques Regular Expression Patterns Time-Bas …
