Flow and CBQoS Sources

The Flow and CBQoS Sources widget provides a list of flow- and CBQoS-enabled nodes and interfaces that are currently monitored by NTA. For each listed device, the Flow and CBQoS Sources widget provides the following details:

A color-coded device status icon
An icon indicating the device type or manufacturer
For each listed source interface, both the incoming and outgoing traffic volume
For all listed flow-enabled devices, the date and time of the last flow packet received by the NTA collector
For all listed CBQoS-enabled devices, the date and time of the last CBQoS poll completed by the NTA collector

Status icon colors

Device status icons are color‑coded as indicated in the following table.

Icon Color	Device Status Indication
Green	The selected source is either able to actively send flow data or it is currently able to provide CBQoS information.
Yellow	Device status is unknown, flow data has not been received, or CBQoS information cannot be polled from the selected device. This color may be displayed for interfaces on a Down node, as it is impossible to determine interface status when the parent node is down.
Red	The selected device is unable to actively provide flow or CBQoS data.

Troubleshoot Flow and CBQoS Sources

In the Flow and CBQoS Sources widget, you can encounter various issues.

Devices not listed in the widget

If you are not seeing expected flow‑ or CBQoS-enabled devices in the Flow and CBQoS Sources widget, confirm that the following is true for your flow‑ and CBQoS-enabled devices:

Confirm that the automatic addition of NetFlow sources option is enabled on the NetFlow Traffic Analysis Settings view. For more information, see Enable the automatic addition of flow sources.
Flow‑enabled nodes and interfaces must be monitored by NPM before they can be recognized in as flow sources in NTA. For more information about adding devices for monitoring by NPM, see Add flow-enabled devices and interfaces to the SolarWinds Platform database.
Flow-enabled devices must be configured to send flow data to the NPM server on which you have installed NTA. For more information about configuring devices to send flows to NTA, see Device configuration examples for NTA.
Confirm that the SolarWinds NetFlow Service has been started in the Windows Services listing. To view a list of services, log on to your NTA server as an administrator, and then open Control Panel > Administrative Tools > Services.

Time stamp "never" or not up to date

If the time stamp of the last received NetFlow or CBQoS data is not as expected, click Manage Flow Sources to confirm that flow monitoring is enabled for the appropriate device and interfaces. For more information, see Flow sources and CBQoS polling.
