Devices & Interfaces tab

The Administration > Devices/Interfaces page Device/Interface (Tree) tab displays information about devices and interfaces that are sending data to NetProfiler.

Roll your mouse pointer over a device to see a popup that provides the status, IP address, name, and type of the device.

Use the plus or minus boxes at the top of the list to expand or collapse all entries. Use the plus or minus box for an individual entry to expand it or collapse it.

When a device entry is expanded to display its interfaces, roll your mouse pointer over the interface to see a popup that lists details about the interface.   moremore

  • Status

  • Device Address

  • Device Hostname

  • Index of the interface

  • Name of the interface (ifDescr; assigned on the data source device)

  • MAC address

  • Type of interface

  • Type description

  • MTU (maximum transmission unit)

  • Inbound speed

  • Outbound speed

  • Inbound traffic (traffic in bits per second that the NetProfiler tracks)

  • Outbound traffic (traffic in bits per second that the NetProfiler tracks)

  • Outbound utilization (percent of device speed that the NetProfiler currently sees being used)

Right-click any underlined device or interface to display a menu of actions you can take.

Much of this information must be obtained from the data source devices. For sources that send data to Flow Gateway appliances, the Flow Gateway appliances use SNMP to obtain the information, which they send to NetProfiler. They use SNMP lookups, if available, to obtain the names of the flow source devices, instead of using DNS name resolution. You can specify which version of SNMP and what community name the NetProfiler uses to contact the devices.

The data source devices must be configured to send flow data (NetFlow, SteelFlow Net, sFlow, IPFIX) to the Alluvio appliance. Flow Gateway can also receive NSEL (NetFlow Security Event Logging) from Cisco ASA (Adaptive Security Appliance) version 9.1(2) or later. However, it uses only the flow byte counts, the same as it would when receiving NetFlow from a router.

When NetProfiler receives data from a device via a Flow Gateway, it automatically lists the device IP address, name, type, and status on the Administration > Devices/Interfaces page. It then attempts to obtain the detailed information using SNMP. It uses the default settings for SNMP unless you have specified other settings.   more

The page displays devices and interfaces in the following format:

NetShark (Device entry line 1)

Interface (Interface entry line)

Flow Gateway (Device entry line 1)

Data source device (Device entry line 2)

Device interface (Interface entry line)

Device interface (Interface entry line)

SteelHead (Device entry line 1)

AppResponse (Device entry line 1)

Third-party device (NetFlow, sFlow, IPFIX) (Device entry line 1)

Device interface (Interface entry line)

Device interface (Interface entry line)

Device entry line 1 identifies the Flow Gateway, NetShark, AppResponse, SteelHead, Sensor or third-party device that is sending data to the NetProfiler.

Device entry line 2 is used in the case of Flow Gateways to identify the devices that are sending data to the Flow Gateways.

The Interface entry lines provide information about each of the devices interfaces. Additionally, each entry has one or more of the following links and indicators:

Status indicator – Color represents status, as described in the legend. The status color is propagated upward. That is, when the display is collapsed, the status of the parent entry shows the status of the most degraded child entry.

Go link – Flow Gateway, NetShark and AppResponse and Sensor entries include a Go link that opens the user interface login page of the device.

Edit link – On device entries, the Edit link opens a window in which you can edit the SNMP settings that the Flow Gateway uses to contact devices or their interfaces. Settings for an individual device can be set to override the global SNMP settings.   more

On interface entries, the Edit link opens a window in which you can edit the interface label that the NetProfiler uses when displaying information about the interface.

Delete link – If a device or interface is no longer carrying traffic, a Delete link is displayed. You can delete the entry for a device that is no longer sending data. If the device resumes sending traffic information, it will automatically be added to the list.

Poll link – A Poll link is included on entries for devices that are sending NetFlow, sFlow, or Packeteer Flow Detail Records to the NetProfiler. Clicking this link causes NetProfiler to place the device at the head of the polling queue. This allows you to receive updated information about this device without waiting for its normal turn in the SNMP polling queue. No Poll link is displayed for Flow Gateway, NetShark, AppResponse and Sensor products because they are in continuous communication with NetProfiler.

The Poll link is not displayed unless polling is enabled on the Global SNMP Settings page, which is accessed by clicking Global SNMP Settings on the Options menu.

Bandwidth Utilization indicator – If NetProfiler is obtaining utilization information from an interface, then the entry for the interface displays a utilization indicator. Roll your mouse pointer over this indicator to see the percent utilization of the interface.

If NetProfiler is receiving data from more than 5000 interfaces, a Show all Devices and Interfaces button is displayed instead of this tab. Click the button to display this tab. It may require several minutes to display a very large list of interfaces and their descriptive information.

Options menu – The Options menu offers the following features:

  • Delete Silent Interfaces   more

  • Global SNMP Settings   more

Note:  Some information associated with physical devices and interfaces is not available for virtual devices and interfaces in an Amazon Web Services Virtual Private Cloud. See AWS VPC device and interface reporting limitations.
