Chapter 4 Using the CSS Logging Features
Specifying a Log File Destination
Specifying a Log File Destination
To specify a destination where the CSS logs subsystem activity, use the logging
command
. You can specify the following locations for log files:
• disk filename - New or existing filename in the disk log directory
• host ip or host - IP address of the syslog daemon on the host or a host name
• log line - CSS active session
Logging to a CSS disk causes the performance of the CSS to degrade.If logging
requires frequent writes to disk (that is, several hundred log messages per day),
the most reliable configuration is to log to a hard disk and store all other system
files on a Flash disk. Although Flash disks generally provide the most reliable way
to store information over time, hard disks endure frequent writes to disk better
than the Flash disks currently available.
To prevent excessive writes to the CSS disk, consider disabling logging to the
sys.log file on disk (see the “Disabling Logging to the sys.log File on the Disk”
section). You can continue sending CSS log information to the sys.log file at an
alternate location. To do this, use either the logging host command to send log
information to a syslog daemon on a host system (see the “Specifying a Host for
a Log File Destination” section) or the logging line command to send (but not
save) log information to an active CSS line (see the “Specifying a Line for a Log
File Destination” section).
This section includes the following topics:
• Specifying a Log File on the Disk
• Disabling Logging to the sys.log File on the Disk
• Specifying a Host for a Log File Destination
• Specifying a Line for a Log File Destination
