⁠OLLDA — Oracle Listener Log Discovery & Analyzer

Lightweight web application for analyzing Oracle listener logs locally. Upload your listener.log files and instantly explore connections, IPs, errors and trends — no data leaves your machine.

⁠Quick Start

docker run -p 5000:5000 jvaldeziodba/ollda

Then open http://localhost:5000⁠ in your browser.

⁠Features

• Parse one or multiple listener.log files (RAC-ready)
• IP Tree view with subnet-level aggregation
• Charts and table views — group by IP, program, OS user, service, instance
• Failures-only filter — identify problematic IPs and ORA- error codes instantly
• Export results to Excel
• Built-in Oracle error code dictionary (ORA-XXXXX descriptions)
• Dark / light theme

⁠Privacy & Security

All processing happens entirely in memory on your local machine. Files are never sent to any external server.
