HI William,
Yes the graphs still display, however the "statistics" table under the
graphs is generated from the raw flow files, not the RRDs. Any time your
graph 'timewindow' goes beyond your remaining stored flows, those stats will
become x's.
You can use nfexpire to prune out the historical flow data (eg regularly via
a cron job) and that will leave all the RRDs/graphs intact.

Download Intel® Parallel Studio Eval
Try the new software tools for yourself. Speed compiling, find bugs
proactively, and fine-tune applications for parallel performance.
