Skyee009/iot-log-analyser ? reverse-engineered prompt

Build me a simple Java app called IoT Log Analyser that can take in log files from IoT devices, read them, and help me understand what is happening in the data.

I want it to be able to load a sample log file, parse the entries, and show useful summaries like counts, errors, timestamps, and any obvious patterns or anomalies. If it makes sense, add a small way to run it locally with Docker too so it is easy to test. Keep the interface straightforward, either a basic command line flow or a very simple app screen is fine.

Please make the project clean and runnable from the existing Maven setup, and include a few example logs or test data so I can see it working right away. If you need current library details or best practices, look them up online.
