Collecting Network Events using Selenium WebDriver

Collecting Network Events using Selenium WebDriver is simple, you just need to enable performance logging in Chrome Desired capabilities.

Once you enable Performance Log, Timeline, Network,
and Page events can be collected.

Enabling Logging in Desired Capabilities

DesiredCapabilities caps = DesiredCapabilities.chrome();
LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.PERFORMANCE, Level.INFO);
caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);  

Collecting Network Events

WebDriver driver=new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), caps);

driver.get("https://codoid.com/about-codoid/");

List<LogEntry> entries = driver.manage().logs().get(LogType.PERFORMANCE).getAll();
System.out.println(entries.size() + " " + LogType.PERFORMANCE + " log entries found");
for (LogEntry entry : entries) {
          System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel() + " " + entry.getMessage());
}  

Note

If tracing is enabled, `ChromeDriver` will start a browser-wide trace when Chrome is launched, and will continue tracing until Chrome closes.
