In this blog I want to talk about enabling NetFlow on a VMware ESX. Netflow support has now been added to vSphere 5; by configuring your virtual switch to send NetFlow statistics to a netflow Analyzer you gain visibility into your virtual infrastructure. To be more specific, you will be able to monitor:
- VM to VM traffic on the same host
- VM to VM traffic on different hosts
- VM to devices outside the virtual environment.
