Management Interface

The Node Manager was developed to monitor Nodes and services running on the network. As any other Nodes, the GUI’s Node will synchronize its local service white pages with other Nodes and consequently receive a list of all services running on the network. The GUI then lists Nodes, services and their respective interfaces and methods and control buttons allows the user to perform actions on Nodes and some services.

A specific viewer was created to inspect the content of DAO services and display all the data entries held by a DAO in the right panel. In addition, the data entry currently selected by the user is displayed with detailed information on each attribute’s value in the lower left panel.

The DAO viewer also offers the possibility of creating a live graph on specific DAO entries. Using our graphic creation “wizard” users can specify data attributes that will act as values for X and Y axis and an attribute for the data categories.  The viewer then listens to data modifications to update graph lines or simply creates the whole graph for static data. Because this viewer reuses the JFreeChart library, we can provide the user with a choice of charts going from standard bar, pie, line, column and area charts to meter, thermometer and compass shaped charts.
