Do not get the Network Websocket message on the remote webdriver. Are there any configurations that we need to set to get the messages on remote webdriver?

Use this code!

**System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + File.separator + "drivers" + File.separator + "chromedriver.exe");

LoggingPreferences loggingprefs = new LoggingPreferences();
loggingprefs.enable(LogType.PERFORMANCE, Level.ALL);

ChromeOptions options = new ChromeOptions();
options.setCapability("goog:loggingPrefs", loggingprefs);
options.addArguments("--enable-devtools-experiments", "--force-devtools-available", "--debug-devtools");

ChromeDriver chromeDriver = new ChromeDriver(options);
DevTools devTools = chromeDriver.getDevTools();
devTools.createSession();
devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty()));`

devTools.addListener(Network.webSocketFrameSent(), webSocketFrameSent -> printData(webSocketFrameSent));
devTools.addListener(Network.webSocketFrameReceived(), webSocketFrameReceived -> printData(webSocketFrameReceived));**

Hi gerardnorton, Im new to coding and have not learned javascript yet. How to do I translate the same thing to python for selenium without using any external web proxy library

@sahajamit
How to translate this to using in Python?

@sahajamit
