Configuration Options
Name Description HTTP access log file enabled Indicates whether this server logs HTTP requests. (The remaining fields on this page are relevant only if you select this check box.)
Gets the loggingEnabled attribute of the WebServerMBean object.
MBean Attribute:
WebServerLogMBean.LoggingEnabledSecure value:
trueLog file name The name of the log file.
MBean Attribute:
WebServerLogMBean.FileNameChanges take effect after you redeploy the module or restart the server.
Rotation type Criteria for moving old log messages to a separate file.
NONEMessages accumulate in a single file. You must erase the contents of the file when the size is too large. Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
SIZEWhen the log file reaches the size that you specify in
FileMinSize, the server renames the file asSERVER_NAME.lognnnnn.TIMEAt each time interval that you specify in
TimeSpan, the server renames the file asSERVER_NAME.lognnnnn.After the server renames a file, subsequent messages accumulate in a new file with the name that you specified as the log file name.
MBean Attribute:
WebServerLogMBean.RotationTypeSecure value:
byTimeChanges take effect after you redeploy the module or restart the server.
Rotation file size The size (1 - 65535 kilobytes) that triggers the server to move log messages to a separate file. The default is 500 kilobytes. After the log file reaches the specified minimum size, the next time the server checks the file size, it will rename the current log file as
SERVER_NAME.lognnnnnand create a new one to store subsequent messages. (Requires that you specify a file rotation type ofSize.)MBean Attribute:
WebServerLogMBean.FileMinSizeMinimum value:
1Maximum value:
65535Begin rotation time Determines the start time (hour and minute) for a time-based rotation sequence.
At the time that this value specifies, the server renames the current log file. Thereafter, the server renames the log file at an interval that you specify in File Time Span.
Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
Use the following format:
H:mm, where
His Hour in day (0-23).
mmis the minute in hour
MBean Attribute:
WebServerLogMBean.RotationTimeRotation interval The interval (in hours) at which the server saves old log messages to another file. (Requires that you specify a file rotation type of
TIME.)MBean Attribute:
WebServerLogMBean.FileTimeSpanMinimum value:
1Limit number of retained files Indicates whether to limit the number of log files that this server instance creates to store old messages. (Requires that you specify a file rotation type of
SIZEorTIME.)After the server reaches this limit, it deletes the oldest log file and creates a new log file with the latest suffix.
If you do not enable this option, the server creates new files indefinitely and you must clean up these files as you require.
MBean Attribute:
WebServerLogMBean.NumberOfFilesLimitedFiles to retain The maximum number of log files that the server creates when it rotates the log. This number does not include the file that the server uses to store current messages. (Requires that you enable Number of Files Limited.)
MBean Attribute:
WebServerLogMBean.FileCountMinimum value:
1Maximum value:
99999Extended Logging Format Fields Returns the list of fields specified for the
extendedlogging format for access.log.MBean Attribute:
WebServerLogMBean.ELFFieldsLog file rotation directory The directory where the rotated log files will be stored. By default the rotated files are stored in the same directory where the log file is stored.
MBean Attribute:
WebServerLogMBean.LogFileRotationDirChanges take effect after you redeploy the module or restart the server.
Rotate log file on startup Specifies whether a server rotates its log file during its startup cycle. The default value in production mode is false.
MBean Attribute:
WebServerLogMBean.RotateLogOnStartupChanges take effect after you redeploy the module or restart the server.
Format This specifies the format of the HTTP log file. Both formats are defined by the W3C. With the extended log format, you use server directives in the log file to customize the information that the server records.
MBean Attribute:
WebServerMBean.LogFileFormatChanges take effect after you redeploy the module or restart the server.
Log time in GMT Specifies whether the time stamps for HTTP log messages are in Greenwich Mean Time (GMT) regardless of the local time zone that the host computer specifies.
MBean Attribute:
WebServerMBean.LogTimeInGMTChanges take effect after you redeploy the module or restart the server.
