Flow exporter is a tool that can take flow data (Netflow, sFlow, IPFIX) from Kafka and export it to Prometheus. nProbe includes both a NetFlow v5/v9/IPFIX probe and collector that can be used to play with NetFlow flows. It will build the source and then run the exporter. Once the updated flows are back into Kafka, they are consumed by database inserters(Clickhouse, Amazon Redshift, Google BigTable...)to allow for static analysis. flow exporter-map ExpMap destination 10.10.10.10 source gigabitEthernet 0/0/0/0 transport udp 9995 version v9.

You can use the Docker command line like so: Ideally in the same docker-compose.yml file as your Prometheus server to make communication easy. Step 1.Enable the NetFlow feature. Step 3.Define one or many flow exporters by specifying export format, protocol, destination, and other parameters. ip flow-export source ip flow-export version 9 ip flow-export destination ! The interface is specified by interface type and location. Hi yes exactly heres one of mine flexible netflow running with source set in exporter , if you have already set it to use the vlan in export theres no requirement to set it in flow monitor too, your flow monitor name will also need to be attached to vlan 1 interface in and out. Description: The flow export source interface is the sending interface for Netflow packets going to the collector. === UPDATE === I use the following java code to set and create the vlan tag (suggested by answer below): In my case this ip address is 10.66.0.2.

For example, a of 100 will cause nprobe to only export 1 flow out of … A Dockerfile is provided for convenience. 5. Step 2.Define a flow record by specifying key and nonkey fields of interest. Switch (config-flow-exporter)# source gigabitEthernet1/0/1 (Optional) ... Switch (config-vlan-config)# ip flow monitor MonitorTest input Associates a flow monitor and an optional sampler to the VLAN for input or output packets. These questions help users make the right choice of applying a Layer 3 or Layer 2 NetFlow configuration.

Our netflow server IP is 10.10.10.10 and UDP port 9995. Create a new Flow Exporter VRF_EXPORTER and specify the IP address and the UDP port of the NetFlow collector, the interface used for the flow export and the timeout for template export in seconds.
