Example: Vyatta NOS flow monitoring

This example shows how to set up flow monitoring between two servers in Azure. The Netflow collector also lies within Azure.

This example uses the following topology:

Vyatta NOS Configuration

First create an exporter and selector.

vyatta@vyatta# set service flow-monitoring exporter e1 udp-collector address '10.0.3.5'
vyatta@vyatta# set service flow-monitoring exporter e1 udp-collector port '9995'
vyatta@vyatta# set service flow-monitoring selector s1 randomly out-of '10'
vyatta@vyatta# commit

Then configure the interface that to monitor the traffic.

vyatta@vyatta# set interfaces dataplane dp0s17 flow-monitoring exporter 'e1'
vyatta@vyatta# set interfaces dataplane dp0s17 flow-monitoring selector 's1'
vyatta@vyatta# commit
Note: IPsec is not required, as UDP flow exports are not restricted in Azure.
