Error messages in Auvik TrafficInsights

Follow

To help identify issues with flow exports, TrafficInsights provides an error message when no data is available. There are six possible error messages:

Below we discuss what the error messages mean and how to resolve them.

Not receiving data

This is the most common error message. It indicates that flow data isn’t being received by TrafficInsights. The likely culprit is a misconfiguration.

Resolution

First, make sure the device is correctly exporting flow data to the appropriate collector. If the correct collector is configured, confirm the device is Approved in the Auvik dashboard. If all looks good but you’re still getting the error message, contact our support team for help. 

Only templates

Flow packets can carry two types of information: templates and data records. Templates are the schemas that describe the meaning and format of the fields in the data records. 

The Only Templates error message means TrafficInsights is receiving only flow templates. TrafficInsights isn’t receiving the data records that carry network traffic information. This usually means flow monitoring has been activated on a network interface or port that isn’t receiving or forwarding traffic.

Resolution

Make sure you’re monitoring the correct interface and that it’s carrying traffic.

No templates 

This error message is the opposite of Only Templates: TrafficInsights is receiving data records, but no templates. As a result, TrafficInsights doesn’t know how to parse and process the data it receives. 

Resolution

Sometimes this issue resolves itself. Templates are sent periodically so it’s possible the error message triggered early, before the templates were received. But if you keep getting this error, check the template configuration on your network devices to make sure they’re exporting correctly.

Parse error 

Parse error means TrafficInsights has encountered an issue parsing the flow data it has received.

Resolution

Make sure your flow data is a type that’s supported by TrafficInsights. We currently support NetFlow v5, NetFlow v9, IPFIX, J-Flow, and sFlow. If your flow data is a supported type, next check whether the network device is using a custom template. If yes, switch to a standard template.

Missing field 

TrafficInsights needs a small set of flow-related information to work: IP addresses, ports, protocol, and bytes. If any of those fields are missing, TrafficInsights can’t process the flows. 

Note: The number of packets per flow (packets) is also a basic parameter but some common devices don’t export packet information. If packet information is the only field missing, TrafficInsights sets the number of packets per flow to one. This way, although the packet information isn’t accurate, TrafficInsights can continue to work. When packet information is missing, no error message is shown.

Resolution

Check that the template definition on your network device includes all four required data fields. If it doesn’t, edit the template to add what’s missing. 

No message - unknown

TrafficInsights show this message when it doesn’t know what’s wrong. 

Resolution

If you see this message, contact our support team.
