Outgoing Interface Utilization

This Flow Monitor dashboard report displays a graph of the outgoing utilization on selected interface for the chosen time period.

Outbound interface utilization is graphed by percentage over time.

Tip: If you experience an unusually low interface utilization, this could be because you have Flow Monitor collecting on a router which is not the network bottleneck. Changing the interface speed on the Flow Sources dialog will give a more accurate reading of its utilization.

Note: sFlow, NetFlow-Lite, and J-Flow data is sent every x number of packets (configurable on the device), whereas regular NetFlow provides statistics about all of the network traffic. This means that sFlow, NetFlow-Lite, and J-Flow data provides a sampling of network traffic data that is not absolutely accurate, whereas NetFlow provides statistics about all network traffic data so that network traffic data is highly accurate. However, typically sFlow, along with the sample packets, sends accurate total interface traffic.
Data sampling methods may result in Interface Overview and Interface Detail reports that appear to have more or less traffic than is shown in the Flow Monitor Home page source information. This is because the sampled data shown in the Interface Overview and Interface Detail reports are derived the sampled data and the Flow Monitor Home page source information is derived from the total interface traffic data.

Note: If you use the Report Zoom tool buttons at the top of this dashboard report, each dashboard report in the Interface Overview report changes date.
