Entries in the definition can include the following:

w

LogFormat specifies the Web server logging feature that supports NCSA, W3C
Extended, and custom log file formats.

By default, the logformat property is w3c. To override, enter custom or NCSA in the
configuration file, for example:

 LogFormat NCSA

Note:  For the NCSA and custom log formats, local time is used to time stamp
transactions and for file rotation.

w

LogInterval specifies the intervals at which new log files are created. Use one of
the following values:

• Hourly: A file is created every hour.

• Daily: A file is created every day at midnight. Default value.

• Weekly: A file is created every Sunday at midnight.

• Monthly: A file is created on the first day of the month at midnight.

• None: A file is created only once, when Web server logging starts.

 LogInterval Daily

w

LogFileSizeLimit specifies the maximum size of the log file in MB. It can be used
with any log interval (weekly, monthly, and so on.) A file is created when the
maximum file size limit is reached or when the defined log interval time elapses.

To override this behavior, specify the size as the loginterval property so that a file is
created only when the log file size limit is reached.

The default LogFileSizeLimit is 10 MB.

 LogFileSizeLimit 35

• Dynamic: Specifies an expression containing the following format:
