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, including the following:
• 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.
