6.4.2 Nodes
Expanding a group in the navigation tree displays the nodes contained in that group. Nodes can be expanded by clicking on the expansion symbol next to their name to reveal the log file types or storage cells included in that node. You can add and remove nodes from the groups in the navigation tree.
6.4.2.1 Adding Nodes
Any computer where the WCCProxy is running can be added to your web interface navigation tree as a node. To add additional nodes follow these steps:
- The "Node Maintenance" screen appears in the display frame (Figure 6–9). The Add Nodes tab is already selected.
Figure 6–9 Add Node
- The location and placement options determine where you would like the new node to appear in the navigation tree relative to existing nodes. By default, new nodes are added after the selected node.
- If no nodes currently exist for the group, skip steps 2 and 3.
- Select an existing node from the list.
- Select a placement option from the radio buttons.
- Enter the name for the new node in text field. Be sure to follow these rules:
- Node names should be valid hostnames or IP addresses. Hostnames must be accessible through the nameserver to be valid. For example, the hostname of a Windows system using DHCP is not listed with the nameserver. In this instance, you would need to enter the IP address.
- Node names should be unique. Entering the name of a node you are already connected to will overwrite the existing node and any data associated with it. The overwritten data includes filters, other logs, categories, callouts, and storage cell information.
- The new node appears under its group in the navigation tree.
6.4.2.2 Removing Nodes
Removing a node removes all the additional data contained in the node from the navigation tree.
To remove existing nodes, follow these steps:
- Select the group you want to remove nodes from in the navigation tree.
- Select the Remove Nodes tab at the bottom of the screen (Figure 6–10).
Figure 6–10 Remove Node
- To select multiple nodes, press CTRL and click on each node. If the nodes are consecutive, press SHIFT and click on the first and last node names.
- The nodes disappear from the navigation tree. If the selected node is contained in multiple groups, removing it from one group will not affect its presence in other groups.
6.4.2.3 Activating Nodes
A new animated icon is displayed when node activation is in progress. Nodes are either active or inactive and by default when you connect to a node or load a profile that connects to other nodes, all the nodes are active. A node is only classified as inactive if SEA cannot connect to it. Inactive nodes appear in the navigation tree with a red "X" through their icon.
Node activation is based on successful communication with WCCProxy. If a node is inactive, you can not activate the node manually.
However, while activating the node, the icon will animate in several stages as shown in the following figure when the connection and handshaking is in progress:
Figure 6–11 Activating Node
- If the Director on the remote node is accessible, a message appears in the display frame (Figure 6–12) and the navigation tree is updated to show the new status.

- If the Director is not accessible, a message appears in the display frame (Figure 6–13) and the navigation tree is not changed.
