Thats because Observiums default interface max speed is 100Gbit. It can be changed by this option in the config:

$config['max_port_speed'] = 12500000000; // Max port speed in RRD; default 100Gbit. Only used upon RRD creation!

If you don't want to delete and recreate your RRD you can change the max value of an existing RRD with the "rrdtool tune"-command

Hello,

On our network, we have aggregate ports with multiple 100G ports.
When the trafic is over 100G, the traffic graph don't work : http://imgur.com/a/JvzIB
But the another graphs, like "Unicast Packets", works without issue.
