Messages are issued with one of the following severity levels: Critical, Error, Warning, Notice, Info, Debug-Summary, Debug-Verbose, or Debug-Data, which are described in Severity Levels Assigned by the Switch.
When a message is sent to a syslog target, the severity is mapped to a corresponding syslog priority value (see RFC 3164).
The three severity levels for extended debugging—Debug-Summary, Debug-Verbose, and Debug-Data—require that log debug mode be enabled (which may cause a performance degradation).
See Displaying Debug Information for more information about debugging.
|Critical||A serious problem has been detected that is compromising the operation of the system; the system cannot function as expected unless the situation is remedied. The switch may need to be reset.|
|Error||A problem has been detected that is interfering with the normal operation of the system; the system is not functioning as expected.|
|Warning||An abnormal condition, not interfering with the normal operation of the system, has been detected that indicate that the system or the network in general may not be functioning as expected.|
|Notice||A normal but significant condition has been detected, which signals that the system is functioning as expected.|
|Info (Informational)||A normal but potentially interesting condition has been detected, which signals that the system is functioning as expected; this level simply provides potentially detailed information or confirmation.|
|Debug-Summary||A condition has been detected that may interest a developer seeking the reason underlying some system behavior.|
|Debug-Verbose||A condition has been detected that may interest a developer analyzing some system behavior at a more verbose level than provided by the debug summary information.|
|Debug-Data||A condition has been detected that may interest a developer inspecting the data underlying some system behavior.|
