Graphs
Unique to Javvin Packet Analyzer enterprise edition. In addition to the standard statistical views, Javvin Packet Analyzer also offers instant graphs which allow you to view your network situation in graphic way. You can view graphic statistics not only for a global network, but also for specific network nodes.
There are multiple graph titles and display options available; this chapter explains how to view graphs, how to select display options and how to save the graphic data.
Graphing statistics
The graphic data in the Graph view and the statistic information in the Summary view are consistent, you can see that from the following figures.
Both the Summary view and Graph view offer statistical data about your network. However, the Summary view only presents the instant statistical data, whereas in Graph view you can see the historical data in a certain time span, e.g. last 120 seconds.
Note: By default, Javvin Packet Analyzer only collects the data on intranet nodes continuously, the data collecting on an Internet node are not initiated until you select it.
Graphs go with the current node, to get global graphs, you must enable no filter and select the project root node in the Project Explorer dock window. Graph display options The Graph view has two sections: graph list and display pane. The graph list shows the graph groups and the title of available graphs for the current node, different nodes may have different graph groups and titles.
