Current Statistics
To refresh statistics at any time, click Refresh Statistics.
- 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
To refresh the list at any time, click Refresh Statistics.
- 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
To refresh the report at any time, click Refresh 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.
