About logging profiles

The Logging Profiles panel in Shared Security lists logging profiles, scaled so that a subset of profiles is visible in the panel at any given time.

A logging profile records requests to the virtual server. A logging profile determines where events are logged, and which items (such as which parts of requests, or which type of errors) are logged. Events can be logged either locally by the system and viewed in the Event Logs screens, or remotely by the client’s server. The system forwards the log messages to the client’s server using the Syslog service.

The logging profile can be associated with multiple virtual servers from multiple devices. Multiple logging profiles can be associated with a virtual server, but the multiple logging profiles cannot have an overlap subset configured. For example, two logging profiles with application security configured and enabled cannot be associated with the same virtual server.The application security and protocol security cannot be configured on the same logging profile or associated with the same virtual server. BIG-IQ Security supports importing logging profiles with spaces in the name. An imported logging profile with spaces in the name can be modified on the BIG-IQ Security system and deployed back to a BIG-IP device. However, the BIG-IQ system does not support creating logging profiles with spaces in the name.

The logging publisher cannot be created or modified by the BIG-IQ Security system. The logging publisher specified by the BIG-IQ logging profile should be the same as that configured on the BIG-IP device.

To close the New Logging Profile properties panel without saving, click Cancel.

To get help on any panel, click the (?) icon in the upper right corner.

Adding logging profiles

Hover over the Logging Profiles header, click the + icon when it appears, and click New Logging Profile. The panel expands to display the New Logging Profile properties.

Editing logging profiles

Hover over the header of the logging profile you want to edit and when the gear icon appears, click it and select Properties to expand the panel.

Adding logging profiles

Use the New Logging Profile screen to configure a new logging profile.

Note: Depending on the settings you configure, you may see only some of the screen elements described here.

Adding logging profiles

  1. Hover over the Logging Profiles header, click the + icon when it appears, and click New Logging Profile. The panel expands to display the New Logging Profile properties.
  2. In the New Logging Profiles screen, review and add or modify the properties as appropriate.
    Property Description
    Name Specify a unique user-provided name for the logging profile. Required.
    Description Specify the optional description for the logging profile.
    Partition Specify the partition to which the logging profile belongs. Only users with access to a partition can view the objects (such as the logging profile) that it contains. If the logging profile resides in the Common partition, all users can access it. Although this field is pre-populated with Common (default), you can set the partition when creating logging profiles by typing a unique name for the partition.
    Note: The partition with that name must already exist on the BIG-IP device. No whitespace is allowed in the partition name.
  3. Select Enabled to the right of one or more logging types to enable those types. A configuration tab is added dynamically when a logging type is selected. Click the tab to configure the logging type.
