AI Log Analysis and Failure Root Cause Analysis Tool

Overview #Personal Development

A troubleshooting analysis support web application that parses, sanitizes, normalizes, and groups application logs, error logs, JSON logs, and stack traces within the browser, presenting root cause candidates traceable back to supporting logs.

Rather than simply passing entire log text to an LLM, the application uses standard code to confirm count, frequency, chronological order, and grouping first, then assigns AI only the interpretation task. Even when AI is unavailable, users can still utilize the Log Viewer, Timeline, Error Groups, and local root cause candidates.

Main Features

• Multiple Format Support: Automatically recognizes Plain Text, Timestamp Log, line-by-line JSON, and multi-line Stack Traces
• Log Preprocessing: Recognizes ERROR / WARN / INFO / DEBUG levels, automatically collapses Health Checks, Polling, and redundant DEBUG logs
• Sensitive Information Protection: Automatically detects and masks Bearer Tokens, JWTs, API Keys, Passwords, Emails, IPv4 addresses, Credit Cards, DB connection strings, etc.
• Smart Normalization: Converts UUIDs, Request IDs, User IDs, Ports, Memory Addresses, and long numbers into unified formats
• Error Grouping: Deterministically groups errors after normalizing dynamic values, displays frequency, first occurrence, and last occurrence
• Integrated Timeline: Displays logs from multiple sources in chronological order
• AI Analysis: Structured analysis via OpenAI-compatible APIs with Citation Validation support
• Human Review: Attaches confirmation status and notes to root cause candidates and remediation suggestions, generates Incident Reports
• Privacy-First: Raw logs are not stored locally; only sanitized copies are sent

Ideal For

• Developers and SREs who want to quickly investigate production incident root causes
• Operations teams who need to efficiently extract important information from massive logs
• Enterprises that want to prevent sensitive information leaks while having AI analyze logs
