Cluster Status - Field HelpEdit any of the following configuration settings on the Cluster Status panel and click Update Configuration. Default port sticky timeThe default sticky time for all future ports on this cluster. 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. Sticky time may be overridden on a per-port basis. The default value is 0, meaning that the port is not sticky. This can also be set at the executor level. Default port stale timeoutThe default number of seconds during which there can be no activity on a connection before that connection is removed. It may be overridden on a per-port basis. The default for port 21 is 900; the default for port 23 is 32,000,000. The default value for all other ports is 300 and can also be set at the executor level. Default port weight boundThe default weight bound for all future ports on this cluster. It may be overridden on a per-port basis. The default value is 20 and can also be set at the executor level. Maximum number of portsThe maximum number of ports on this cluster. The default value is 8 and can also be set at the executor level. Default maximum servers per portThe default maximum number of servers per port on this cluster. It may be overridden on a per-port basis. The default value is 32 and can also be set at the executor level. Default port protocolThe default port type for all future ports on this cluster. It may be overridden on a per-port basis. Possible values are TCP, UDP, or both protocols (TCP/UDP) and can also be set at the executor level. The default value is TCP/UDP. Bandwidth to be sharedThe 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. Primary host for the clusterThe nonforwarding address of the primary host for the cluster in dotted decimal format. The following current statistics are also displayed on the Cluster Status panel: Cluster addressThe dotted decimal IP address of this cluster. Cluster alias on NICSpecifies whether or not the cluster has been aliased. Possible results are: configured, unconfigured, or unavailable. SYNs on active connectionsThe number of redundant connection requests. A high rate of growth in this statistic could indicate slow or no response from servers in this cluster. SYNs on finished connectionsThe number of requests for new connections, where those new connections are the same as current connections in FIN state. FINs received before SYNsFINs dropped due to no connection. Rapid increase in this statistic could indicate that the stale timeout is too low. Any percentage greater than 1% of total packets forwarded could indicate a problem. ACKs received before SYNsACKs dropped due to no connection. Rapid increase in this variable could indicate that the stale timeout is too low. Any percentage greater than 1% of total packets forwarded could indicate a problem. RSTs received before SYNsRSTs dropped due to no connection. Rapid increase in this variable could indicate that the stale timeout for this cluster is too low. Any percentage greater than 1% of total packets forwarded could indicate a problem. Total packets droppedPackets dropped due to no connection. Rapid increase in this variable could indicate that the stale timeout for the ports on this cluster is too low. Any percentage greater than 1% of total packets forwarded could indicate a problem. SYN on SYN for quiesced serverThe number of requests for new connections, where those new connections are the same as connections already received for a server that has been quiesced. KBytes transferred per secondThe number of kilobytes transferred in a one second interval. Connections per secondThe current number of connections per second for this cluster. List of PortsA list of currently active ports and the number of servers that are currently active. |
