Item Description
Health Monitoring Type
Select a health monitoring method that a real service group uses to monitor
a real service:
z
TCP: Monitors the availability of an application port by establishing
TCP connections.
z
ICMP: Monitors the reachability of a server by sending ICMP packets.
z
HTTP: Monitors the availability of an HTTP service through HTTP
access.
z
FTP: Monitors the availability of an FTP server through FTP.
z
DNS: Monitors the availability of a DNS server through DNS.
IMPORTANT:
You can display and configure health monitoring by selecting High
Reliability > Load Balance > Health Monitor. For more information, see
Setting Health Monitoring Parameters
.
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:
At present, redirection is applied to firewall load balancing mode and
other methods are applied to server load balancing.

Time
When you add a server or a network device to a cluster, because some
servers or network devices cannot take on a large amount of services
immediately, you can enable the slow-online function. With slow-online
enabled, after the server or network device goes online, the LB device will
not assign services to it in the standby time. After the standby time is
reached, the LB device will assign services to the server or network device
gradually within the slow-online time. After the slow-online time is reached,
the LB device will assign services to the server or network device normally.
