Specifying Log File Options
Viewing the Error Log File
The
error
log file, located in
admin/logs
in the server root directory, 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:
1.
Access the Enterprise Administration Server and choose the Preferences tab.
2.
Click the View Error Log link and click OK.
You can also view the server’s active and archived log files from the Server
Manager. For more information regarding these log files, see “The View Access
Log Page,” in the online help.
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.
For example, you can set up your files to rotate every hour, and Enterprise
Server saves and names the file “
access.199907152400
,” where
“name|year|month|day|24-hour time” is concatenated together into a single
character string. The exact format of the access log archive file varies
depending upon which type of log rotation you set up.
Enterprise Server offers the two types of log rotation for archiving files:
• Internal-daemon log rotation —this type of log rotation happens within
the HTTP daemon, so the server doesn’t need to restart.
• Cron-based log rotation —this type of log rotation is based on the time
stored in the
cron.conf
file. For more information about cron controls,
see “Using Cron Controls (Unix Only),” on page 78.
