Interface Utilization (if-mib)

System.NetworkManagement.ifMIB.NetworkAdapter.CurrentUtilization (Rule)

Collects the utilization of the interface

Knowledge Base article:

Summary

This rule collects the current utilization of a network interface. The current utilization of a port or interface is the ratio, expressed as a percentage, of the total number of bits sent over some interval over the total number of bits that could have been sent in that same interval. A value of 100% means that, had more traffic arrived in that period, some would have been dropped due to lack of capacity.
