Yes, the nbox comes with both ntop and nprobe installed. As nboxes can install an optional harddisk, you can plan to use ntop as long-term monitoring application able to save traffic statistics on disk. However we suggest to use an external (i.e. installed on a box other than the nbox) ntop if you plan to collect a great amount of traffic. This because an excessive ntop load, might have a negative impact on the overall nbox performance.
