Network bandwidth is "always" rated in bits - not Bytes - so in answer to your first question - it's bits for throughput. Now for Data Sent / Rcvd - that will be bytes.
Percentage of traffic is either the sum of all traffic for a given host compared to network traffic as a whole, or a specific protocol compared to all traffic. For example, host A total traffic sent and rcvd is 100MB and total network traffic is 1GB, host A will be 10%. If you're looking at a specific host and looking at hourly buckets for the last 24 hours, then the percents show there will help show that hosts busy times. If a host as 90% of his daily traffic at 3am - what's happening at 3am? Hope that helps? Just play around with it a little a do some testing monitoring traffic to/from your own workstation. Maybe do some downloads (of known size) and see how it impacts the various graphs for your host?

Currently I have installed NTOP on Centos 5.1 and I am able to see some network data being graphed. But there is no documentation given whether NTOP is showing Network Throughput in MBytes or MBits for ex I am getting Throughput Min: 163.7k , Max: 3.0 M and Last 859.4k and there are some options like anomalia, upper,lower and trend (30min). Under All Protocols -> Traffic I can see per hour data received and data sent but I am not able to figure out how NTOP is currently the percentage of this data Time Tot. Traffic Sent %Traffic Sent Tot. Traffic Rcvd % Traffic Rcvd 10 AM 287.8 MBytes 0.3% 32.9 MBytes 1.4 % How NTOP is calculating %Traffic Sent /Rcvd? Please let me know if you need any further inputs .
