Monitoring the network interface ensures you are alerted if there are high levels of activity. For example, programs accessing the internet, remote users, files or large print jobs can all use network bandwidth to complete their tasks, but more destructive elements such as worms or viruses can also cause a high level of activity over the network.
There can only be one Performance Monitoring Check for Network Usage per network interface.
The Performance Monitoring Check for Network Usage samples the total number of bits transferred in either direction over a 5 second period, and generates an Alert if the average bits exceed the configured alert threshold of the current available bandwidth.
For example, you can configure the check to generate an alert if the average utilization is above 40%.
