Elmah error logging, can I just log a message?
Yes, you can use ErrorSignal without throwing an exception.
ErrorSignal.FromCurrentContext().Raise(new NotSupportedException());For the custom message, you can create a custom exception.
var customEx = new Exception("Hello I am testing Elmah", new NotSupportedException()); ErrorSignal.FromCurrentContext().Raise(customEx);
I know this is an old question, but if you don't want to create an exception you can also use
var error = new Error{ Source = eventType.ToString(), Type = $"Trace-{eventType}", Message = message, Time = DateTime.UtcNow};ErrorLog.GetDefault(HttpContext.Current).Log(error);as shown in this answer.
