What visualization applications are available?
Visualization front-ends will be supported by Caimis to display cflowd data, based on the ARTS data format. For example, the program “FlowScan” produces graph images that provide a continuous, near real-time view of the network border traffic. FlowScan binds together (1) a flow collection engine (a patched version of cflowd), (2) a high performance database (Round Robin Database – RRD) and (3) a visualization tool (RRDtool). It examines flow data and maintains counters reflecting what was found. Counter values are stored using RRDtool, a database system for time-series data. Finally, FlowScan uses visualization capabilities of both RRDtool and other front-ends to report on the processed flow data. The program “xartsprotos” will display a stacked bar chart of traffic (in bits/sec) per IP protocol versus time. It uses ARTS files as input, and permits the user to cycle through all of the datasets present in the input files (typically, there would be a dataset per interface per router). Yo
