Cisco ASR9K netflow decoding

[mmip-labs]

Hi there!

I'm trying to receive Netflow v9 from our Cisco ASR9K, but for some reason, akvorado can't decode it.

My Cisco's config:

flow exporter-map MMIP-NF-COLLECTOR
version v9
!
dscp 24
transport udp 2055
source Loopback2
destination 10.100.7.95 vrf MGMT

Error in akvorado logs:

{"level":"error","error":"NetFlowV9 NetFlowV9 [version:9 type:Decode obsDomainId:2081: templateId:260] Error template not found","exporter":"10.100.5.1","time":"2024-05-07T14:24:18Z","caller":"akvorado/inlet/flow/decoder/netflow/root.go:203","module":"akvorado/inlet/flow/decoder/netflow","message":"error while decoding NetFlow/IPFIX"}

I tried other Netflow collector (nfdump) and it could receive Netfllow successfully.

One log message is not enough to conclude. Check the troubleshooting section of the documentation.

Dear, vincentbernat
After reading https://demo.akvorado.net/docs/troubleshooting#no-packets-exported i have found my mistake ) I forgot to set default-sampling-rate in inlet.yaml Now, akvorado is working properly. Thank you for your product!

Also see the proposed configuration for these routers (including the sampler-table): https://demo.akvorado.net/docs/operations#ncs-5500-and-asr-9000.
