Total received since started
Total number of packets received by the executor since it started.

Sent to nonforwarding address
Total number of packets sent to the nonforwarding address since the executor started.

Processed locally on this machine
Total number of packets, not for the nonforwarding address or any cluster, but to be processed locally by the Dispatcher machine.

Sent to collocated server
Total number of packets explicitly forwarded to a server collocated on the Dispatcher machine.

Forwarded to any cluster
Total number of packets forwarded to any cluster.

Not addressed to active cluster/port
Total number of packets not addressed to any active cluster and port.

KBytes transferred per second
The number of kilobytes transferred over a one-second interval.

Connections per second
The current number of connections per second.

Headers too short
Total number of packets discarded by the executor because the packet headers are too short.

No port or servers
Total number of packets that were forwarded to a cluster, but were discarded by the executor because either the port:
  • Did not exist
  • Existed but had no servers configured to it

Network adapter failure
Total number of packets not forwarded because of a network adapter failure.

Forwarding errors
Total number of packets with forwarding errors since the executor started. Examples of forwarding errors are:
  • There was an error extracting an encapsulated packet that came in from a wide area Load Balancer
  • An attempt to forward the packet to either a local or remote server failed


Configuration Settings

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

Nonforwarding address
The address of this machine in either dotted-decimal or host name format. Any packet sent to this address will not be forwarded by the Dispatcher component.

Client gateway address
The address of the network router through which traffic returns to the client. This applies only to port forwarding method values of NAT/NAPT and content-based routing. Type the address of the client gateway in either dotted-decimal or host name format.

FIN count
The maximum number of finished connections before the Dispatcher garbage collector clears the memory reserved for those connections. The default value is 4000.

FIN timeout
The maximum number of seconds that connections have been finished before the Dispatcher garbage collector clears the memory reserved for those connections. The default value is 60.

Wide area network port number
A port number that is unused on all of the Dispatcher machines in a wide area network. The Dispatcher machines use this port to exchange wide area information. The default value is 0.

Shared bandwidth (kbytes)
The level of bandwidth (kilobytes per second) to be shared at the cluster or executor level. Sharing bandwidth at the cluster level allows ports to share a maximum amount of bandwidth across several ports (applications/protocols) within the same cluster. Sharing bandwidth at the executor level allows clusters within the entire Dispatcher configuration to share a maximum amount of bandwidth. The default value is 0. If the value is 0, then bandwidth cannot be shared.
Note:Specify a maximum shared bandwidth value that does not exceed the total bandwidth (total server capacity) available.

Maximum number of clusters
The maximum number of clusters for load balancing. The default value is 100.

Default maximum ports per cluster
The default maximum number of ports per cluster. This can be overridden on a per-cluster basis. The default value is 8.

Default maximum servers per port
The default maximum number of servers per port. This can be overridden on a per-cluster or per-port basis. The default value is 32.

Default port stale timeout (seconds)
The default number of seconds, during which there is no activity on a connection, before that connection is removed. The default for port 21 is 900; the default for port 23 is 32,000,000. The default for all other ports is 300. It can be overridden on a per-cluster or per-port basis.

Default sticky time (seconds)
The default port sticky time for all future clusters. 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. Default port sticky time can be overridden on a per-cluster or per-port basis. The default value is 0, meaning that the port is not sticky.

Default port weight bound
The default weight bound for all future ports. This can be overridden on a per-cluster or per-port basis. The default value is 20.

Default port protocol
The default port type for all future ports. This can be overridden on a per-cluster or per-port basis. Possible values are TCP, UDP, or both protocols TCP/UDP. The default value is TCP/UDP.
