Shows different ways of handling errors globally. Setting a global exception handling filter is the usual.

GlobalFilters.Filters.Add(new SpecialHandleErrorAttributeCreatedByYou());

You would derive a new Attribute from HandleErrorAttribute and put your logic in there, overriding the OnException method.

public override void OnException(ExceptionContext filterContext)

However this will not show you exceptions that are handled by other code. That is the point, they are handled so they do not continue to bubble up the stack. You would have to put code in each of those catch blocks to either do what you want.

Yes it is possible you can override. HandleErrorAttribute And register it globally 

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(YourNewHandler());
...
}

Global error handling:

public class MvcApplication : System.Web.HttpApplication
{
        protected void Application_Error(object sender, EventArgs e)
        {
            Exception exception = Server.GetLastError();
            Server.ClearError();
            Response.Redirect("/Home/Error");
        }
}

Or override OnException method:

public class HomeController : Controller
{
    protected override void OnException(ExceptionContext filterContext)
    {
        Exception ex = filterContext.Exception;
        filterContext.ExceptionHandled = true;

        var model = new HandleErrorInfo(filterContext.Exception, "Controller","Action");

        filterContext.Result = new ViewResult()
        {
            ViewName = "Error",
            ViewData = new ViewDataDictionary(model)
        };
    }
}
