🚀 FastAPI Log Parser API

This project provides a simple RESTful API using FastAPI to parse and analyze server/application log files from a local logs/ directory. It exposes endpoints to filter, query, and retrieve statistics on log entries.

📁 Project Structure

FastAPi_for_log_data/ ├── d.py # Contains parse_log_line() to split log lines into components ├── main.py # FastAPI application with endpoints for log access and analysis ├── logs/ # Folder containing .log files to be parsed (can include sample logs) ├── .gitignore └── README.md

📜 Sample Log Format

The log files are expected to have entries in the following format:

Each line must contain:

• Timestamp
• Log level (INFO, WARNING, ERROR, etc.)
• Component name
• Message

---

⚙️ How It Works

• On app startup, all .log files inside the logs/ directory are read and parsed.
• Each line is split into: timestamp, level, component, and message.
• All parsed entries are stored in memory as a list of LogEntry objects.

🧪 API Endpoints

GET /logs

Retrieve logs, with optional filters:

GET /logs/{log_id}

Retrieve a single log entry by its UUID.

GET /logs/stats

Returns:

Total number of log entries Count by log level Count by component
