Overview

For security auditing purposes, enable load balancing logging to record load balancing information. Load balancing logging includes basic logging and NAT logging.

Load balancing basic logging generates logs for the following events:

• The state of a link or link group changes.

• The health monitoring result of a link changes.

• The number of connections on a link or virtual server reaches or drops below the upper limit.

• The connection establishment rate on a link or virtual server reaches or drops below the upper limit.

• A primary/backup server farm switchover occurs between server farms specified for a virtual server.

• A primary/backup server farm switchover occurs between server farms specified for an LB action.

Load balancing NAT logging records NAT session information, including IP address and port translation information and access information.
