iPerf3 Web Interface: Real-time Monitoring and Control

This code provides a web interface for running and monitoring iPerf3 commands using Flask and jQuery.

The 'index.html' file contains the HTML code for the web interface. It includes a title, two buttons for starting and stopping the iPerf3 command, and a '

' element for displaying the command output. The script section includes jQuery code that sends AJAX requests to the Flask server to start, stop, and stream the command output.

The 'app.py' file is a Flask application that handles the requests from the web interface. It defines three routes: '/' for the homepage, '/start' for starting the iPerf3 command, '/stream' for streaming the command output, and '/stop' for stopping the command.
When the 'Start Command' button is clicked, a POST request is sent to '/start' route. The Flask server starts the iPerf3 command as a subprocess and captures its stdout. It then creates a generator function 'stream()' that continuously yields the output of the command. The output is sent to the web interface using Server-Sent Events (SSE) and displayed in the '
' element.

When the 'Stop Command' button is clicked, a POST request is sent to '/stop' route. The Flask server terminates the iPerf3 command subprocess and clears the output on the web interface.
The server also provides a route '/stream' to check if a command is running and stream its output. If a command is running, the server sends the command output in real-time using SSE. If no command is running, it returns a JSON response indicating that no command is running.
To run the application, you can execute the 'app.py' file using a Python interpreter. The Flask server will start running and you can access the web interface by visiting http://localhost:5000 in your web browser.
