Overload Utilization Percentage

Counter

Overload Utilization Percentage counts bits over time and compares this value to 
the maximum utilization possible (bandwidth). A threshold for this percentage 
value can be set in Expert Alarms.

Overload utilization percentage can help catch network overloads. 

The default for a 100MB network is 25% of maximum utilization.
