- 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.

WebSphere Application Server - Edge Component Information Center Web site.
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.
