The Error Log File

The error log lists all the errors the server has encountered since the log file was
created. It also contains informational messages about the server, such as when the
server was started and who tried unsuccessfully to log in to the server.
To view the error log file, perform the following steps:

Archiving Log Files

You can set up your log files to be automatically archived. At a certain time, or after
a specified interval, Enterprise Server rotates your access logs. Enterprise Server
saves the old log files and stamps the saved file with a name that includes the date
and time they were saved.
Access log rotation is initialized at server startup. If rotation is turned on,
Enterprise Server creates a time-stamped access log file and rotation starts at server
startup.
Once the rotation starts, Enterprise Server creates a new time stamped access log
file when there is a request that needs to be logged to the access log file and it
occurs after the previously-scheduled "next rotate time."

Using Cron-based Log Rotation (UNIX/Linux)

You can configure several features of your Enterprise Server to operate
automatically and set to begin at specific times. The cron daemon checks the
computer clock and then spawns processes at certain times. (These settings are
stored in the
ns-cron.conf
This cron daemon controls scheduled tasks for your Enterprise Server and can be
activated and deactivated from the Administration Server. The tasks performed by
the cron process depends on the various servers. (Note that on Windows NT and
Windows 2000 platforms, the scheduling occurs within the individual servers.)
Some of the tasks that can be controlled by cron daemons include scheduling
collection maintenance and archiving log files. You need to restart cron control
whenever you change the settings for scheduled tasks.
