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 real server or real server group changes.

• The health monitoring result of a real server changes.

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

• The connection establishment rate on a real server 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.
