Server log levels

The level of logging defines how detailed the server log is. A lower level, such as Unusual Activity, provides more detail because multiple types of events are logged.

Level Writes an event to the log when:
Severe Error (1) A severe problem or critical condition occurs, such as a server failure.
Error (2) An error condition occurs, such as a failed connection attempt.
Warning (3) A warning condition occurs, such as the server not starting as an NT service.
Unusual Activity (4) Unusual activity occurs, such as a user trying to log in with an incorrect username.
Information (5) Any significant action occurs, such as a user action timing out.
Events for the selected level and all higher levels are logged. If you select Unusual Activity, the server logs all severe error, error, warning, and unusual activity events.
