title: open chrome devtool inspector-inspector in selenium
body: <p>I wish to save (secure) WebSocket traffic from some web pages. I tried saving HAR using <code>chrome-devtool</code>. But apparently, <a href="https://groups.google.com/forum/#!topic/google-chrome-developer-tools/jUOLFqpu-2Y" rel="nofollow noreferrer">it doesn't save the WebSocket traffic</a>. However, I found <a href="https://stackoverflow.com/questions/29953531/how-to-save-websocket-frames-in-chrome/44957049">this answer</a> which suggests I can log all requests if I can change the <code>SDK</code> and log all <code>SDK.networkLog.requests()</code>. Still, to run <code>SDK</code> code, I would need to open the <code>chrome inspector-inspector</code> from Selenium. I know I can open the dev-tool using selenium from <a href="https://stackoverflow.com/questions/36311191/how-to-open-chrome-developer-console-in-selenium-webdriver-using-java">this answer</a>. Any suggestion on how to open the <code>inspector-inspector</code>? Or alternate way to log <code>WebSocket</code>? 
  Thanks in Advance! </p>
