Disable logging in Selenium ChromeDriver

Just a code snippet with a ChromeDriver configuration to run Chrome browser in a headless mode with the least possible amount of logging:

ChromeDriverService service = ChromeDriverService.CreateDefaultService();
service.EnableVerboseLogging = false;
service.SuppressInitialDiagnosticInformation = true;
service.HideCommandPromptWindow = true;

ChromeOptions options = new ChromeOptions();

options.PageLoadStrategy = PageLoadStrategy.Normal;

options.AddArgument("--window-size=1920,1080");
options.AddArgument("--no-sandbox");
options.AddArgument("--headless");
options.AddArgument("--disable-gpu");
options.AddArgument("--disable-crash-reporter");
options.AddArgument("--disable-extensions");
options.AddArgument("--disable-in-process-stack-traces");
options.AddArgument("--disable-logging");
options.AddArgument("--disable-dev-shm-usage");
options.AddArgument("--log-level=3");
options.AddArgument("--output=/dev/null");

Browser = new ChromeDriver(service, options);

Explanation

EnableVerboseLogging - false to disable verbose logging for the ChromeDriver executable.

SuppressInitialDiagnosticInformation - when set to true the initial diagnostic information is suppressed when starting the driver server executable.

HideCommandPromptWindow - the command prompt window of the service should be hidden.

PageLoadStrategy - When set to PageLoadStrategy.Normar driver waits for pages to load and ready state to be 'complete'.

Chrome browser arguments

This is the list of command-line arguments I use to get the best performance possible on Raspberry Pi 4. Full list of Chrome arguments.

--window-size=1920,1080 - set windows size to the specified values

--no-sandbox - Disables sandbox mode for all processes

--headless - Run in headless mode, i.e., without a UI or display server dependencies.

-disable-gpu - Disables GPU hardware acceleration.

--disable-dev-shm-usage - The /dev/shm partition is too small in certain VM environments, causing Chrome to fail or crash (see http://crbug.com/715363). Use this flag to work-around this issue (a temporary directory will always be used to create anonymous shared memory files).

--disable-crash-reporter - Disable crash reporter for headless. It is enabled by default in official builds.

--disable-extensions - Quite clear what it does ;)

--disable-in-process-stack-traces - Disables the in-process stack traces.

--disable-logging - logging should be already disabled in production builds, but better to double disable.

--log-level=3 - Sets the minimum log level. Valid values are from 0 to 3: INFO = 0, WARNING = 1, LOG_ERROR = 2, LOG_FATAL = 3
