Interface Traffic
This dashboard report shows the incoming and outgoing traffic transmitted over the selected interface for the chosen time period.
Interface traffic is graphed in bytes over time. The 95th percentile for both inbound and outbound interface traffic is graphed for the chosen time period.
You can easily lower the time graph scale on the configuration dialog to see the lower level traffic that is more difficult to see at the default scale setting.
You can choose to display and sort sender traffic by bytes, packets, or flows using the Display and sort by option on the report configuration dialog. Providing alternate sorting methods allows you to monitor and identify hosts that are the largest consumers of interface resources other than bandwidth.
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.
