How to monitor your data center infrastructure

I've found this very interesting article NetFlow vs. sFlow for Network Monitoring and Security: The Final Say that debates over the 2 main monitoring solution for network devices.

By looking at the protocols itself we can find a more broad deployment and adoption in application as well (example config for HAProxy load balancer using sflow to monitoring host resources).

This example sflow video  provides more details about the protocol and how it can be used across data center to monitor and visualize server as well as network infrastructure.
