An Alt title is “Where has all my internet usage gone”…
I’ve remove ntop as i found it too problematic, and not giving me the info i require. I have now installed ipfm (all though its no longer maintained) and bwstat, These seem to do what i need for the mean time, and should be simple enough to not cause me problems. In the future i might have to upgrade to pmacct, as it uses less cpu and has better options.
Next problem was having to add every host to the sql data base for reporting, so i found a good article that does something similar for PowerDNS and ISC Dhcp.
