Port Status - Field Help
Current Statistics
- Cluster
- The cluster name or address to which clients connect. The cluster value is either a
symbolic name or in dotted-decimal format. A cluster value of 0.0.0.0 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.
- Port number
- The number of the port.
- Number of servers
- The number of servers currently active on the 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 active connections
- The current total number of active connections for this port.
- Connections per second
- The current 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 is 300.
- Weight bound
- The weight bound for this port. The default value is 20 and can also be set
at the executor and cluster levels.
- Maximum number of servers
- The maximum number of servers for this port. The default value is 32 and can
also be set at the executor and cluster levels.
- Default sticky time (seconds)
- The sticky time for this port.
Sticky time is used to create an affinity relationship between a client and a specific
server. After the sticky time has been exceeded, the client might be sent to a server
different from the previous. The default value is 0, meaning that the port is not
sticky. Sticky time can also be set at the executor and cluster levels.
Note: Once a client has an affinity record at the port level, all subsequent requests from that
client within the sticky time interval are not analyzed by rules. Port affinity has precedence over
checking.
Lists
- List of Servers
- The numerical dotted-decimal address (such as 9.37.52.11) 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 within the list, highlight the server you want to remove and click
Remove.
- List of Rules
-
- Rule name - rules that are currently active.
- Rule priority - the priority assigned to the rule. Lower priority
rules are evaluated first. (A rule with a priority of 1 is evaluated
before a rule with a priority of 2.) The first rule that is satisfied is used.
After a rule is satisfied, no further rules are evaluated.
- Rule type - rules types are based on things such as: client IP address,
time of day, connections per second for a port, active connections total for
a port, content, and always true.
To remove a rule from the list, highlight the rule you want to remove and click Remove
Please refer to the "Configuring rules-based load balancing" section of the
Load Balancer Administration Guide for more details
about rules-based load balancing.
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 servers results.
