6.3.2  Navigation

Using SEA, it is possible to monitor the binary event log files generated by a wide variety of computers all from a single web interface. In order to simplify the process of monitoring these diverse information sources, the web interface uses a hierarchical navigation tree composed of groups, nodes, categories, and binary event log files.

6.3.2.1  Navigation Tree Hierarchy

The entries in the navigation tree are as follows:

Folder
Description
Groups
Multiple computers that are logically associated. Groups contain one or more nodes.
Nodes
Individual computers. Each node contains two types of log files: System Log and Other Logs.
System Log
The binary system event log where the computer writes system information. By default, the System log contains Real Time Monitoring and Full View.
Real Time Monitoring
Automatic analysis results.
Full View
Manual analysis results for the system event log.
Other Logs
Any other binary event log files saved on the computer. These can include old files, files from other systems, and examples. Optionally, the other logs can be further divided by categories (See Section 6.8.1 for information on modifying SEA to use categories).

6.3.2.2  Features of the Navigation Tree

Figures 6–5 and 6–6 describe the features and functions of the navigation tree.

Feature
Description
Current Selection is Highlighted
In most browsers, the currently selected entry in the Navigation Tree is highlighted (Figure 6–5).
Collapsing Navigation
The tree structure can be collapsed to the group level (Figure 6–5).
Expanding Navigation
Click on the expansion symbol for an entry to view its contents. Once an entry is expanded, the expansion symbol changes to a collapse symbol. To hide the contents again, click the collapse symbol.
Icons
Each entry in the tree has a name and an icon that indicates its type. For example, in Figure 6–6 you can tell that the jarjar.cxo.dec.com node is inactive because of its icon.
Customizing the Navigation Tree
You can customize the navigation tree by adding and removing groups, nodes, categories, and binary event log files (see Section 6.4).
Viewing Results
You can view the results of automatic analysis and initiate manual analysis from the navigation tree (see Section 6.5).
Refreshing Navigation
If you modify the entries in the navigation tree, you may need to refresh the display so your changes appear. To refresh the navigation tree, click the Refresh Tree button.
