Item Description
Health Monitoring
Success Criteria
Specify the health monitoring success criteria.
• If you select All, health monitoring succeeds only when all the selected health
monitoring methods succeed.
• If you select At Least and specify a value, health monitoring succeeds when the
number of succeeded health monitoring methods reaches the specified value.
Offset If you select UDP Packet Load Hash as the algorithm, this field sets the payload for
performing hash algorithm.
The payload field is determined by offset and length. Offset refers to the relative
position of the payload content with respect to the whole payload of a packet;
length refers to the length of the payload content starting from the offset. You can
specify up to 10 payload fields.
Length
Minimum Active Real
Service Number Specify the minimum number of active real services to participate in scheduling
when you select Local Priority for Scheduler.
Real Service
Troubleshooting
Select a method that the real service group uses to handle existing connections
when it detects that a real service fails:
• Keep Connection—Does not actively terminate the connection with the failed
real service. Keeping or terminating the connection depends on the timeout
mechanism of the protocol.
• Disconnection—Actively terminates the connection with the failed real service.
• Redirection—Redirects the connection to another available real service in the
real service group.
IMPORTANT:
Redirection is applied to firewall load balancing mode and other methods are
applied to server load balancing.
