Cluster
The cluster name or address to which clients connect. The cluster value is either a symbolic name or in IP address format. A cluster value of 0.0.0.0 (IPv4) or 0::0 (IPv6) can be used to specify a wildcard cluster. Please refer to the "Use a wildcard cluster to combine server configurations" section in the Load Balancer Administration Guide for more information.
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.
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.
KBytes transferred per second
The number of kilobytes transferred per second on this port.
Total connections
The total number of connections for this port.
Pre-established connections
TCP connections for which an initial packet has been received, but the connection is not yet fully established.
Active connections
The number of connections in the active state for this port.
Finished connections
The number of connections that are in the FIN state for this port. A client sends a FIN packet to let the server know that the transaction is finished.


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.
Selection algorithm
There are two selection algorithms that are supported for this port.
  • Connection (default) - server selection is based on a simple round-robin selection.
  • Affinity - server selection is based on client affinity.
Weight bound
The weight bound for this port. The default value is 20.


Lists

To refresh the list at any time, click Refresh Statistics.

List of servers
The IP address and weight (such as 10) of the currently-active servers. 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.

Please refer to the "Configuring rules-based load balancing" section of the Load Balancer Administration Guide for more information regarding rules-based load balancing.
