Date: 14 September 2015, 04:38:55  for some of the requested 
information.  Other bits I am not sure how to collect.
The switch stats go back 68 days to when the machine was powered on 
after some electrical work elsewhere in the building. 

Show more output: 

pciconf -lv igb0 
pciconf -lv igb1 
camcontrol devlist 
zpool list 
zpool status 
zfs list 
cat /etc/sysctl.conf 
cat /boot/loader.conf 

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 (, plugins for Cacti and bsnmpd (man bsnmpd) to get similar graphics:
