[Ntop] RRD plugins

[Lawrence Tang]

Hi,     1. Can NTOP provide report for user MB usage on a specific date range using RRD ? like 1/12/2003 to 31/12/2003 ?     2. How to configure RRD to update chart for yearly,monthly,weekly and daily at 12 midnight everyday ?     3. Can we add an additional column for VOIP port (like the existing http,ftp,Mail...) under network traffic report for each ip address ? At the meantime, they are all group under "other IP"       Thanks in advance.   Best Regards,   Lawrence Tang
