SolarWinds Orion Part 2 - Monitoring Interfaces

After the new node is added in part 1, all the interfaces will be listed out for you. Typically, you would pay particular attention to interfaces that are prone to congestion and link errors e.g. WAN interfaces. Solarwinds also automatically calculate the bandwidth utilization based on the default bandwidth of the interface. For example, Solarwinds assumes 1000Mbps bandwidth for Gigabit Ethernet (GE) interface and traffic usage of 8Mbps will constitute less than 1% utilization rate. What if that interface is connected to your service provider device that provides only 10Mbps? That would become 80% high utilization instead!

To customise the actual bandwidth, click on the interface and click on "edit interface" button. Check on "Custom Bandwidth" and enter the actual transmit and recieve bandwidth.
