Event Logging
33
All log targets can be viewed via the web User Interface, regardless of whether they specify any external logging
(or logging to Flash memory).
5.6.2. Viewing logs in the CLI environment
The command line allows logs to be viewed, and you can select which log target, or all targets. The logging
continues on screen until you press a key such as RETURN.
In addition, anything set to log to console shows anyway (see Section 5.1.1.2), unless disabled with the
troff
command.
5.7. System-event logging
Some aspects of the operation of the overall system have associated events and messages that can be logged.
Logging of such events is enabled via the
system object attributes shown in Table 5.2 below :-
Table 5.2. System-Event Logging attributes
system
object attribute Event types
log
General system events.
log-debug
System debug messages.
log-error
System error messages.
log-eth
General Ethernet hardware messages.
log-eth-debug
Ethernet hardware debug messages.
log-eth-error
Ethernet hardware error messages.
log-panic
System Panic events.
log-stats
"One second stats" messages
Specifying system event logging attributes is usually only necessary when diagnosing problems with the
FB6000, and will typically be done under guidance from support staff. For example,
log-stats
causes a
log message to be generated every second containing some key system statistics and state information, which
are useful for debugging.
Note that there are some system events, such as startup and shutdown, which are always logged to all log targets,
and to the console and flash by default, regardless of these logging attributes.
5.8. Using Profiles
The log target itself can have a profile which stops logging happening when the profile is disabled. Also, each
of the external logging entries can have a profile. Some types of logging will catch up when their profile comes
back on (e.g. email) but most are immediate (such as syslog and SMS) and will drop any entries when disabled
by an Inactive profile.
