Status Monitoring and Statistics
configured to get messages of severity info and greater, the NVRAM target gets messages of severity
warning and greater, and the memory buffer target gets messages of severity debug-data and greater.
All the targets are associated by default with a filter named DefaultFilter, that passes all events at or
above the default severity threshold. All the targets are also associated with a default match expression
that matches any messages (the expression that matches any message is displayed as
Match : (none)
from the command line). And finally, each target has a format associated with it.
To display the current log configuration of the targets, use the following command:
show log configuration target {console | memory-buffer | nvram | session | syslog
<ipaddress> [local0 ... local7]}
To configure a target, there are specific commands for filters, formats, and severity that are discussed in
the following sections.
Severity
Messages are issued with one of the severity level specified by the standard BSD syslog values
(RFC 3164),
critical, error, warning, notice, and info, plus three severity levels for extended
debugging,
debug-summary, debug-verbose, and debug-data. Note that RFC 3164 syslog values
emergency and alert are not needed since critical is the most severe event in the system.
The three severity levels for extended debugging, debug-summary, debug-verbose, and debug-data,
require that debug mode be enabled (which may cause a performance degradation). See the section
“Displaying Debug Information” for more information about debugging.
To configure the severity level of the messages sent to a target, there is more than one command that
you can use. The most direct way to set the severity level of all the sent messages is to use the following
command:
Table 19: Severity levels assigned by the switch
Level Description
Critical A serious problem has been detected which is compromising the operation of the
system and that the system can not function as expected unless the situation is
remedied. The switch may need to be reset.
Error A problem has been detected which is interfering with the normal operation of the
system and that the system is not functioning as expected.
Warning An abnormal condition, not interfering with the normal operation of the system, has
been detected which may 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 and simply provides potentially detailed information
or confirmation.
Debug-Summary A condition has been detected that may interest a developer determining 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.
