VAgent Code Assist Performance Monitor

This Visual Studio Code extension is designed to help you monitor the performance of your AI coding assistant, VAgent Code Assist. It provides real-time latency measurements, tracks memory usage of the extension host, and generates detailed reports with charts.

Features

Real-Time Performance Monitoring

The extension adds a status bar item to the bottom right of your VS Code window that displays the real-time latency of VAgent Code Assist's suggestions.

Performance Report

Run the Code Assist Performance: Show Performance Report command from the Command Palette (Ctrl+Shift+P or Cmd+Shift+P) to open a detailed report. The report includes:

• Average, minimum, and maximum suggestion latency.
• A time-series graph of latency measurements.
• A time-series graph of memory usage (RSS and Heap).
• A table of recorded memory usage over time, including a basic analysis for potential memory leaks.

Record and Playback

Use the record and playback feature to gather a consistent set of performance data for analysis. This is ideal for creating a performance baseline.

• Start Recording: Use the Code Assist Performance: Start Recording command to clear all previous data and begin a new session.
• Playback Session: Use the Code Assist Performance: Playback Session command to automatically generate 5 code snippets, with a delay between each, and record the performance metrics for each event.

HTML Export

The Code Assist Performance: Export Report to HTML command allows you to save the generated report as a shareable HTML file.

Manual Code Generation

For manual testing and quick data collection, the Code Assist Performance: Generate Code command (Ctrl+I or Cmd+I) opens a new file and automatically triggers a code suggestion from VAgent Code Assist.

How to Use

1. Start a Recording: Open the Command Palette and run Code Assist Performance: Start Recording.
2. Generate Data: Use one of the following methods to create performance data:
   • Playback Session: Run the Code Assist Performance: Playback Session command to automatically run a series of tests.
   • Manual Typing: Simply type in a text editor and observe the status bar for real-time latency metrics.
   • Generate Code: Run the Code Assist Performance: Generate Code command to quickly trigger a single code suggestion.
3. View and Export the Report: Once you have some data, run either Code Assist Performance: Show Performance Report to view it in a webview or Code Assist Performance: Export Report to HTML to save it as a file.
