Server Status - Field Help

Configuration Settings

Edit any of the values on the Server Status panel by clicking Update Configuration.

Collocated
Specifies whether or not this server is on the same machine as the Dispatcher machine. The collocated field does not apply to the Windows platform. Possible values are:
  • no (default)
  • yes

Note: For Windows platform, Dispatcher can be collocated (without using this field) when the port is configured with nat or cbr forwarding methods (but not with the mac forwarding method).

Current status
The current status of the server. Possible values are:
  • Down
  • Up

Server weight
The weight for this server that is used in load balancing between servers on the same port. The default value is 10.
Note: You will be unable to update the server weight while the manager is running and the server "fixed weight" value is "no" (the default). If you want to set the server weight and do not want the manager to update the server weight you set, then set the "fixed weight" value to "yes"

Fixed weight
Indicates whether the server weight should stay fixed when the manager is running. The default is NO. When fixed weight is specified as NO, the manager will adjust the weight for this server for optimal performance. If fixed weight has been specified as YES, the server weight is 'fixed' and will not be updated by the manager.

Sticky for rule
Default is YES, which specifies that the server is to stay sticky when the port is designated as sticky. Setting this option to NO (non-stick) overrides the sticky affinity of the port when a request is routed to a server which is experiencing an overflow.

Network router address
The IP address of the router that will be used to resolve the address of the remote server if this server is used as part of a wide area network. If there is a router address defined, the Dispatcher will encapsulate packets before forwarding them. This field does not apply if the server is local (on the same subnet as the Dispatcher machine).

HTTP Advisor Request
This field holds the string which will be used by the HTTP advisor to query the health of the servers. This value defaults to "Head/HTTP/1.0". It is present for all servers, but it will only be valid for servers which are advised upon by the HTTP advisor.
Note: This field is disabled until an HTTP advisor is started.

HTTP Advisor Response
This field holds the string which will be used by the HTTP advisor to compare to the real response that is received from the server. This string value defaults to "null".
Note: This field is only available after you have started an HTTP advisor.

Cookie Value (only applicable to content-based routing forwarding method protocol)
An arbitrary value, set by the administrator, that represents the server side of the cookie name/cookie value pair. The cookie value, along with the cookie name, acts as an identifier to Network Dispatcher allowing Network Dispatcher to send subsequent requests of a website to the same server machine.


Current Statistics

Server
The server is the unique IP address of the TCP server machine as either a symbolic name or in dotted-decimal format. Or, if you use a unique name that does not resolve to an IP address you must provide the server address.

Server address
The unique IP address of the TCP server machine as either a host name or in dotted-decimal format. If the server is unresolvable you must provide the address of the physical server machine

Port number
The number of the port to which this server is defined.

Cluster address
The IP address of the cluster associated with this server.

Quiesced Status
Specifies whether or not this server has been quiesced. If the server has been quiesced, then no new connections from a different client can be sent.

Map port
The port to which you are using for load balancing. Allows a client's request to be received on one port and to be transmitted on a different port on the server machine. You may load balance client requests to multiple server daemons running on the same physical machine. This is only applicable when using the NAT/NAPT or content-based routing forwarding method protocols.

Return Address
A unique IP address or hostname, used only when the server's forwarding method is NAT/NAPT or content-based routing. It must be different than the cluster address, server address and NFA. You must specify the return address value when the server is added and it can not be changed after the server exists.

The return address is used by the Dispatcher machine in order to process the content of the request, rather than sending the packet directly to the client.
Note: Return address applies only to Dispatcher with NAT/NAPT or content-based routing forwarding method protocols.

Kbytes transferred per second
The number of kilobytes transferred in a one second interval

Total connections
The total number of connections on this server.

Active connections
The number of connections that are in the active state.

FINed connections
The number of connections that are in the FIN state. A client sends a FIN packet to let the server know that the transaction is finished.

Completed connections
The number of connections that are completed. A connection is in complete state after the FIN packet is received and garbage collection has been performed in order to free the memory used to hold this connection information.



Lists

List of server metrics
A list of system metrics which have been added to the server and the results of executing those metrics on the server.
