[ixpmanager] Aggregate graphs break graphing

Hi Miku,

sorry for the delay! You caught me as I was leaving for RIPE72 and am 
only now catching up.

Great!

Hmmm, odd. I think there may be a DNS lookup issue in the code. If you 
put an IP address in for hostname it may work. If you could file a bug 
report on GitHub, that'd be great :-)

Possibly a summation of max speeds issue. Can you email me the mrtg conf 
file directly (i.e. off list?)?

What IXP are you from?
