Interface groups

The NetProfiler tracks traffic volumes and utilization percentages (where available) on a per-interface basis for all interfaces from which it receives traffic information. For convenience, you can aggregate interface statistics into groups. You can define policies for interface groups to generate an alert if a specified condition occurs. You can also generate reports to provide an interface-oriented view of network performance.  

To simplify network monitoring and troubleshooting, you can define views of your network based on regions, locations, business groups, functions or other classification attributes. You can also specify Preferred Interfaces. Traffic statistics for preferred interfaces are precomputed and cached for quick access (except when a VXLAN license is enabled).  more

Each "network view" can include all relevant interface groups. Each interface group can contain subgroups and individual devices and interfaces. All devices and device interfaces that are sending traffic information to NetProfiler can be listed by a search tool for easy selection and inclusion in an interface group or a network view.

Adding a device to a group adds all the device’s interfaces that are sending data to the NetProfiler appliance. Adding a "reporting device," such as the Flow Gateway appliance, adds all that device's routers and all the routers' interfaces. If additional interfaces on that device begin sending data to the NetProfiler appliance at some future time, they are automatically added to the interface group also.  more

Use the Definitions > Interface Groups page to perform the following actions. Note that VXLAN views are not editable except for the names and descriptions assigned to their virtual network identifiers.

• Define a network view

• Define interface groups within a network view

• Add interfaces and devices to an interface group

• Define subgroups within an interface group

• Add interfaces and devices to a network view

• Move or copy groups, devices or interfaces between groups using drag & drop

• Import or export an interface group or network view

• Delete interfaces, devices, interface groups and network views

• Considerations

• • Preferred interfaces

  • WAN interface groups

  • SD-WAN interface groups

  • XML files

After interface groups and network views have been set up, interface performance can be monitored on the Reports > Navigate Network page.
