Internet usage statistics (Ubuntu)

Question

linux

Looking for a program to collect statistics on Internet use. For Ubuntu. The functionality is something like this:

• Size received/sent (per hour/day/week/month/year)
• Average access speed
• The total time that the Internet was connected (in general, all the time when the computer is turned on :-)

Answer 1

Darkstat can do the first two - packages.ubuntu.com/maverick/darkstat

Answer 2

zabbix/acti? :)

Answer 3

ntop

Answer 4

vnstat. There is no third point, but is it really needed? You can take it from the logs.
Plus, it extrapolates how much will be released per day / week / month.
