Network traffic monitor

I installed vnstat a few months ago to check how much traffic was going over our internet connection. I am impressed how simple it is to use, There are other projects like ntop but I found for what I wanted, it was an overkill.. I have a cron job that runs every 5 min’s collecting stats on the 3 Network interfaces (Internet, LAN, DMZ). The output from vnstat on the command line is ok, but could be better:) Here comes vnstat PHP frontend to the rescue. It’s a small php frontend to vnstat which displays all the data that is captured by vnstat in a nice easier to understand format. The requirements are webserver + php, I have install lighttpd and php-cgi,php-gd (pretty graphs)…
While on the subject I also use squid to cache web traffic, for easy monitoring of this i use sarg. Its ok for what I want..
