What visualization applications are available for CAIDA members?
Visualization tools are being created to display cflowd data, based on the ARTS data format. For example, 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). You may also initiate time-domain aggregation from within xartsprotos, and you can also print a plot to a file (in PostScript). Sample screen shots of these kinds of visualization outputs are available at: Sample Screen Shots Q: What if I want a different time granularity, e.g. daily instead of 5 min.? A: You aggregate using one or more of the aggregation utilities (artsasagg, artsnetagg, artsprotoagg and artsportmagg). In the typical case, you might have a cron job that aggregates for you on a regular basis (for example, once a night you could create hourly and daily aggregates). This is how you
