Server --> Logging --> HTTP

Enable HTTP Logging

Enables logging of HTTP requests.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LoggingEnabled

Default: true

Valid values:

• true

• false

Configurable: yes

HTTP Log File Name

The HTTP request log file The name of the file that stores HTTP requests. If the pathname is not absolute, the path is assumed to be relative to the root directory of the machine on which the server is running.

This value is relevant only if HTTP logging is enabled.

To include a time or date stamp in the file name when the log file is rotated, add java.text.SimpleDateFormat variables. Surround each variable with percentage (%) characters.

For example, access_%yyyy%_%MM%_%dd%_%hh%_%mm%.log

If you do not include a time and date stamp, the rotated log files are numbered in order of creation filenamennnn, where filename is the name configured for the log file.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogFileName

Default: access.log

Configurable: yes

Format

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: weblogic.management.
configuration.
WebServerMBean

Attribute: LogFileFormat

Default: "common"

Valid values:

• "common"

• "extended"

Configurable: yes

Dynamic: yes

Log Buffer Size

The maximum size (in kilobytes) of the buffer that stores HTTP requests. When the buffer reaches this size, the server writes the data to the HTTP log file. Use the LogFileFlushSecs property to determine the frequency with which the server checks the size of the buffer.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogFileBufferKBytes

Units: kilobytes

Minimum: 0

Maximum: 1024

Default: 8

Configurable: yes

Rotation Type

Criteria for moving old HTTP requests to a separate log file:

• size. When the log file reaches the size that you specify in MaxLogFileSizeKBytes, the server renames the file as LogFileName.n.

• date. At each time interval that you specify in LogRotationPeriodMin, the server renames the file as LogFileName.n.

After the server renames a file, subsequent messages accumulate in a new file with the name that you specified in LogFileName.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogRotationType

Default: "size"

Valid values:

• "size"

• "date"

Configurable: yes

Maximum Log File Size

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.

0 causes the file to grow indefinitely.

This property is relevant only if you choose to rotate files by size.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: MaxLogFileSizeKBytes

Units: kilobytes

Minimum: 0

Default: 5000

Configurable: yes

Rotation Period

The interval (in minutes) at which the server saves old HTTP requests to another log file. This value is relevant only if you use the date-based rotation type.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogRotationPeriodMins

Units: minutes

Minimum: 1

Maximum: 2147483647

Default: 1440

Configurable: yes

Rotation Time

Determines the start time for a time-based rotation sequence. At the time that this value specifies, the server renames the log file. Thereafter, the server renames the log file at an interval that you specify in LogRotationPeriodMins.

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 is already past, the server calculates the initial rotation time based on the rotation start time and the rotation period.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogRotationTimeBegin

Configurable: yes

Limit Number Of Retained Log Files

Specifies whether the number of files that this WebLogic Server creates to store old messages should be limited. After the server reaches this limit, it overwrites the oldest file.

MBean: weblogic.management.
configuration.LogMBean

Attribute: NumberOfFilesLimited

Default: false

Log Files to Retain

The maximum number of log files that this WebLogic Server creates when it rotates the log. (This field is relevant only if you check the Limit Number Of Retained Log Files box.)

MBean: weblogic.management.
configuration.LogMBean

Attribute: FileCount

Default: 7

Flush Every

The interval (in seconds) at which the server checks the size of the buffer that stores HTTP requests. When the buffer exceeds the size that is specified in the LogFileBufferKBytes property, the server writes the data in the buffer to the HTTP request log file.

MBean: weblogic.management.
configuration.
WebServerMBean

Attribute: LogFileFlushSecs

Units: seconds

Minimum: 1

Maximum: 360

Default: 60

Configurable: yes
