Looks like you removed some parts ('traffacct' and 'emailreports') from 
the configuration file that you won't use. Monitorix expects to read the 
original configuration file, and you think you won't use an option, just 
leave it disabled (with 'n').

It seems then that FreeBSD folks have removed (or perhaps changed the 
name) of the option 'kern.random.sys.seeded'. Do you know if there exist 
a different way to know the entropy on a FreeBSD system?

Meanwhile as a work-around comment out the lines from 293 to 296 in the 
'system.pm' file of your FreeBSD system. I believe that the last error 
about 'unable to convert '' to float is just a consequence of the 
previous problem.
