The assistant supports background monitoring tasks, listing active jobs, and on-demand log analysis. It’s designed for quick, repeatable troubleshooting of latency spikes and packet loss without leaving the terminal.</p> <p>Key features:</p> <ul> <li> <code>/run &lt;host&gt; &lt;minutes&gt; &lt;threshold_ms&gt;</code> starts a background monitoring task.</li> <li> <code>/list</code> shows active or completed background tasks.</li> <li> <code>/analysis</code> summarizes logs and uses GitHub Copilot to produce AI observations.</li> <li>JSONL logging for both raw events and alerts.</li> </ul> <h2> Demo </h2> <p>Run the assistant:</p> <ul> <li><code>python .\tnc_interactiveAssistant.py</code></li> </ul> <p>Example session:</p> <ul> <li>Start a monitor: <code>/run 8.8.8.8 1 120</code> </li> <li>List tasks: <code>/list</code> </li> <li>Analyze logs with AI observations: <code>/analysis</code> </li> </ul> <p>Demo video/screenshot:<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fn61s56ff6uchyjyhq9tr.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fn61s56ff6uchyjyhq9tr.png" alt=" " width="800" height="310"></a></p> <h2> My Experience with GitHub Copilot CLI </h2> <p>I used GitHub Copilot CLI to quickly iterate on command handling, background task orchestration, and the AI analysis flow. It helped me:</p> <ul> <li>Draft the command parsing and task management scaffolding.</li> <li>Refactor analysis logic into reusable prompt context builders.</li> <li>Embed GitHub Copilot's agentic workflows to perform analysis (especially useful when you have large dataset)</li> </ul> <p>It accelerated development while keeping the solution focused on a clean CLI experience.</p> <h2> Technologies </h2> <ul> <li>Python 3.10+</li> <li>GitHub Copilot SDK</li> <li>Asyncio for Concurrency</li> </ul> <h2> Repository </h2> <p><a href="https://github.com/turbotmy/NetChatAI" rel="noopener noreferrer">https://github.com/turbotmy/NetChatAI</a></p> <h2> Author </h2> <p>GitHub: <a class="mentioned-user" href="https://dev.to/turbotmy">@turbotmy</a></p> devchallenge githubchallenge cli githubcopilot
