Managing Logging Profiles in Shared Security

About logging profiles

The Logging Profiles screen lists both default logging profiles that cannot be modified, and other logging profiles that can be modified. A
logging profile
records requests and malformed 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 is configured to record the system and viewed in the Event Logs screens, or remotely by an external logging system. The system forwards the log messages to the client’s server using the Syslog service.
The following default logging profiles are imported from the BIG-IP device:
  • Log all requests
  • Log illegal requests
  • global-network
  • local-dos
The BIG-IQ Centralized Management system creates the following logging profiles:
  • The
    templates-default
    logging profile is the default logging profile for application templates.
  • The
    afm-remote-logging-profile
    logging profile can be created automatically when configuring Network Security event monitoring. For information on the configuration process, refer to the
    Monitoring Network Security events
    topics in
    F5 BIG-IQ Centralized Management: Monitoring and Reporting
    on
    support.f5.com
    .
  • The
    dos-remote-logging-profile-afm
    or
    dos-remote-logging-profile-asm-afm
    logging profile can be created automatically when configuring DoS event monitoring. For information on the configuration process, refer to the
    Monitoring DoS events
    topics in
    F5 BIG-IQ Centralized Management: Monitoring and Reporting
    on
    support.f5.com
    .
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. Application security and protocol security cannot be configured on the same logging profile or associated with the same virtual server.
BIG-IQ Centralized Management 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 system and deployed back to a BIG-IP device. However, BIG-IQ does not support creating logging profiles with spaces in the name.
The logging publisher cannot be created or modified by the BIG-IQ Centralized Management system. The logging publisher specified by the BIG-IQ system logging profile should be the same as that configured on the BIG-IP device.
If a BIG-IQ system adds or removes data collection devices (DCDs), that causes a change to be made to the remote logging event settings in the
templates-default
logging profile on the BIG-IQ system. A subsequent deployment of that BIG-IQ configuration to a managed BIG-IP device or a rediscovery or reimport of that BIG-IP device will show differences for the
templates-default
logging profile, since the BIG-IQ version of that profile has changed.

Create logging profiles

You create logging profiles to configure the kind of information to log for objects that support logging.
  1. Click
    Configuration
