Using the CSS Logging Features
Logging Overview
Logging Overview
The CSS generates log messages to assist you with debugging and monitoring
operations. By default, the CSS saves boot and subsystem event log messages to
log files on its hard or Flash disk. The content of these files is recorded in ASCII
text. You can also configure the CSS to send log messages to an active CSS
session, e-mail address, or another host system.
The maximum size of a log file is 50 MB for hard disk-based systems, and 10 MB
for Flash disk-based systems.
The boot log messages are the result of the boot process. The CSS saves these
messages in the boot.log file.
The subsystem log messages are subsystem events that occur during the operation
of the CSS. The CSS saves these messages in the sys.log file, created when the
first loggable subsystem event occurs. The CSS determines which subsystem
messages to log by its configured logging level. By default, the CSS logs events
on all subsystems with a level of warning. The warning level designates that the
CSS logs fatal, alert, critical, error, and warning messages for the subsystem.
You have the option to log subsystem messages at a different level than the default
warning level. The level you specify instructs the CSS to log subsystem activity
that occurs at that level and the activity greater than that level.
In addition to informational messages, the CSS also logs notice, warning, error,
critical, alert, and fatal messages.
You can display or copy a log file using the show log or copy log command,
respectively. For details on the show log command, see the
"Showing Log Files"
section. For details on the copy log command, see the
"Copying Log Files to an
FTP or TFTP Server"
section. You need SuperUser privileges to use the show log
command.
