Hello,
We are forwarding NetFlow v9 data from a core switch and VPN to NiFi. In NiFi, we are using the NetFlow Listener processor to listen to the NetFlow traffic.
However, the processor is unable to process the data, and the only information we could find in the logs after enabling debug logging is the following:
2025-03-06 16:25:29,502 WARN com.cloudera.nifi.netflow.ListenNetFlow: ListenNetFlow[id=861330c9-6ffc-1e81-9978-be1bba4f3524] Sender [/0.0.0.0:00000] Cached Template ID [259] not found
2025-03-06 16:25:29,502 DEBUG com.cloudera.nifi.netflow.ListenNetFlow: ListenNetFlow[id=861330c9-6ffc-1e81-9978-be1bba4f3524] Sender [//0.0.0.0:00000] Version [9] FlowSet ID [259] Length [604]
Is there anyone faced such issue and help us to identify the cause of this issue and suggest possible solutions?
Thank you for your help.
