I have stopped displaying Netflow traffic in the widgets of some interfaces and in others I do display the traffic, protocols of the same node. please any suggestions.?

* port 2055 is enabled to receive Netflow,

* interfaces in CBQoS polling management are enabled.

* in Performance Monitor, the input and output packets are displayed.

Netflow is configured on the switch itself to send the flows. Verify that the flows are enabled and are being sent to the SolarWinds pollers. https://documentation.solarwinds.com/en/success_center/nta/content/nta-cisco-netflow-configuration-sw1982.htm

Hi Eugene_99 your best bet is to go back to the basics and work your way up from there.

Where there any changes to the node(s) like an IOS update or a hardware swap-out?
Are their other machine types in your environment that are sending NetFlow to SW and is SW displaying it correctly?
If yes, then compare the NetFlow commands between machine types.
Look at the NetFlow exporter commands to make sure the exporter source is still valid.
- Example was the exporter source a VLAN that has since been removed or shutdown?
Is the exporter source IP address the same as the node(s) managed IP address in SW?
Is 'ip flow monitor' configured on the interface?
is 'ip flow monitor' correctly configured on the interface?
Does the interface support 'ip flow monitor'
Is the node configured to store NetFlow in SW?
If the interface configured to store NetFlow in SW?

Hopefully all of this will help you in troubleshooting your issue.
