Executor Status - Field Help

Configuration Settings

Edit any of the values on the Executor Status panel and 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 client gateway is 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 a port (or ports) to share a maximum amount of bandwidth across several ports (applications/protocols) within the same cluster. Sharing bandwidth at the executor level allows a cluster (or clusters) within the entire Dispatcher configuration to share a maximum amount of bandwidth. The default value is 0. If the value is zero, then bandwidth cannot be shared.
Note: You should specify a maximum shared bandwidth value that does not exceed the total bandwidth (total server capacity) available.

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

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

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

Default port stale timeout
The default number of seconds during which there can be 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 may be overridden on a per-cluster or per-port basis.

Default sticky time
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 may be sent to a server different from the previous. Default port sticky time may 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. It may 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. It may 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.


Current Statistics

Total received since started
Total number of packets received by the executor since it was 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 were too short.

No port or servers
Total number of packets discarded by the executor which were forwarded to a cluster, but were discarded 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 which came in from a wide area network Dispatcher
  • An attempt to forward the packet to either a local or remote server failed
