http://origami.phys.rpi.edu/~healer/trouble for some of the requested

pciconf -lv igb1
The output port statistics from the switch will not help. :(
We need it daily or weekly graphics the packets to quickly identify "narrow" place.
Using packages Cacti (cacti.net), plugins for Cacti and bsnmpd (man bsnmpd) to get similar graphics:
