Log Analyzer

A lightweight web app for parsing log files and surfacing "interesting" events.

Current support:

• Python logs
• C/C++ logs
• AddressSanitizer crash reports
• Warning detection
• Crash detection with basic crash subtype classification
• Multi-line crash grouping for tracebacks and related failure blocks

Run locally

uv run python app.py

or

python app.py

Then open http://127.0.0.1:8000.

Setup

This project uses uv for any dependecies. Although not strictly required it helps with thing like type checking. To use uv with the project run uv sync

What it detects currently

• Warnings such as warning, deprecated, and Python warning classes
• Python crashes such as tracebacks, syntax errors, import errors, assertion errors, and memory errors
• C/C++ crashes such as segmentation faults, assertion failures, aborts, floating point exceptions, stack smashing, and undefined references
• AddressSanitizer reports such as SEGV, heap-use-after-free, heap-buffer-overflow, and related memory safety failures
