7. In Log Rotation Type, select By Size or By Date.
l By Size: Rotates the log when it exceeds the value entered into the Log
Buffer Size parameter.
l By Date: Rotates the log after the number of minutes specified with the
Rotation Period parameter.
8. If you have selected
Size as the Rotation Type, in the Max Log File Size K
Bytes field specify the file size (1 - 65535 kilobytes) that triggers the server to
move log messages to a separate file.
After the log file reaches the specified size, the next time the server checks the
file size, it will rename the current log file as
FileName.n and create a new one
to store subsequent messages.
9. If you have selected Date as the Rotation Type, set the Rotation time to the first
date when you want the log file to rotate.
Use the following java.text.SimpleDateFormat format to specify a date and time:
MM-dd-yyyy-k:mm:ss. For information about this format, refer to the J2EE Javadoc.
If the time that you specify has already past, then the server starts its file rotation
immediately.
10. If you have selected Date as the Rotation Type, set the Rotation Period to the
number of minutes after which the log file will rotate.
Common Log Format
The default format for logged HTTP information is the common log format at
http://www.w3.org/Daemon/User/Config/Logging.html#common-logfile-
format
. This standard format follows the pattern:
host RFC931 auth_user [day/month/year:hour:minute:second
UTC_offset] "request" status bytes
where:
host
Either the DNS name or the IP number of the remote client
RFC931
Any information returned by IDENTD for the remote client; WebLogic
Server does not support user identification
