Comprehensive and Detailed Explanation From Exact Extract:

This message means the NetFlow collector is receiving flow data from a device whose IP address is not managed in the SolarWinds platform, so the flow data is discarded. To resolve this, you must either:

Add the sending device as a managed node using the correct IP address, or

Enable the "Allow matching nodes by another IP" option in the NetFlow settings, which allows SolarWinds to match flows sent from an interface IP or secondary IP.

A "no data" message in NetFlow charts usually indicates that the flow collector service is not receiving or processing flow data. One of the primary troubleshooting steps recommended in the SolarWinds documentation is to restart the collector service. This resolves issues caused by service interruptions, memory leaks, or flow processing errors.

The documentation states:

"If NetFlow charts display 'no data,' verify that the NetFlow collector service is running. Restart the collector service if necessary, as service interruptions can cause a lack of flow data display."

According to the SolarWinds documentation:

"The maximum number of resources that can be displayed in any flow chart or view is 50. Attempting to display more may impact performance and will not be rendered in the UI."

This ensures optimal performance and usability of the charts within the platform.

SolarWinds NTA maps flow sources to nodes by matching the IP address. If a device exports flows using a secondary IP (not the one defined as "primary" in SolarWinds), and the setting "Allow matching by other IPs" is not enabled, the flow will not map to a known node. The documentation explains:

"If flow packets are received from an IP address not designated as primary in SolarWinds, and matching by other IPs is disabled, the flow source is not linked to a node. Enable the setting to match by any device IP to resolve this issue."

Device Studio is designed to enable support for complex devices and can poll multiple OIDs as part of a single custom poller definition. While Universal Device Poller (UDP) is also used for custom SNMP polling, it is generally limited to a single OID per poller. Device Studio is intended for use cases that require combining and correlating multiple OIDs for richer, template-based device monitoring.
