# LogImpl.Fatal Method (Object)

Logs a message object with the `FATAL` level.

[Visual Basic]
Overridable Overloads Public Sub Fatal( _
ByVal message As Object _
) _
Implements ILog.Fatal
[C#]
public virtual void Fatal(
object message
);

#### Parameters

message
  The message object to log.

#### Implements

ILog.Fatal

#### Remarks

This method first checks if this logger is `FATAL` enabled by comparing the level of this logger with the `FATAL` level. If this logger is `FATAL` enabled, then it converts the message object (passed as parameter) to a string by invoking the appropriate IObjectRenderer. It then proceeds to call all the registered appenders in this logger and also higher in the hierarchy depending on the value of the additivity flag.

WARNING Note that passing an Exception to this method will print the name of the Exception but no stack trace. To print a stack trace use the Fatal form instead.
