Hi Guys,
Good day!
Having issue with one of our device there's no node details (No top talkers etc).
Also upon checking on (netflow>NTA Summary) manage source the device is not included and last received netflow was last month.

Before this device is working.
Netflow traffic Analyzer settings:
Netflow management - Already enabled
CBQos poliing - Enabled
Tried removing and then add the node back but still don't work.
How can we troubleshoot and resolve this issue?
Thank you
