Cluster
The cluster name or address to which clients connect. The cluster value is either a symbolic name or in IP address format.

Cluster address
The address to which clients connect. The cluster address can be either the IP address or the host name of the machine. If the cluster value is not resolvable, you must provide this IP address of the physical machine.

Port number
The number of the port.

Number of servers
The number of servers running on this port.

Maximum server weight
The maximum server weight for servers on this port. The weight is based on internal counters in the executor, feedback from the advisors, and feedback from a system-monitoring program, such as Metric Server.

Selection algorithm
  • affinity - specifies that connections from the same client will be routed to the same back-end server.
  • connection (default) - specifies that requests within a connection will be routed to the same back-end server.
  • Connection+Affinity - specifies that Load Balancer will use the affinity feature to select the server for the first connection, and Load Balancer will maintain that server selection for subsequent connections after the first connection is used.

Total packets received
Total number of packets received by the port.

Packets forwarded
Total number of packets, destined for this port, that are forwarded to a server.

Packets generated
Total number of packets generated by Load Balancer for the port. These packets include ICMP packets that Load Balancer sends out to request information. Generated packets are packets that are not received from a client.

Packets discarded
Total number of packets that are destined to the port but are discarded because the server was not configured to the port.

Packets processed locally
Total number of packets to be processed locally by the Load Balancer.

Packets with errors
Total number of packets discarded due to packet error. For example, if the packet headers are too short, the packets are discarded.

Connections per second
The number of connections per second for this port.


Configuration Settings

Edit any of the values on the Configuration Settings tab, then click Update Configuration.

Stale timeout (seconds)
The number of seconds during which there can be no activity on a connection before that connection is removed. The default value for port 21 is 900; the default value for port 23 is 259,200. The default value for all other ports is 300.

Sticky time (seconds)
Specifies the amount of time to maintain an affinity record. If this amount of time passes and an affinity record has not been used again, the record will be deleted.

Weight bound
The weight bound for this port. The default value is 20.


Lists

List of servers
Specifies the IP address and weight (such as 10) of the servers that are currently active. Weights are applied to all servers on a port. Requests are distributed between servers based on their weights relative to each other. For example, if one server is set to a weight of 10 and the other to 5, the server set to 10 should get twice as many requests as the server set to 5.

To remove a server, highlight the server in the list and click remove.


List of rules
Specifies the list of rules for this port.


Report

Server
The server that is being reported on.

Active %
The proportion of weight given to the active connections.

New %
The proportion of weight given to the new connections.

Port %
The proportion of weight given to the port.

System %
The proportion of weight given to the system load determined by the metric server results. .
