Summary
In this chapter, we looked at additional ways in which we can utilize Python to enhance our network monitoring efforts. We began by using Python's Graphviz package to create network topology graphs with real-time LLDP information reported by the network devices. This allows us to effortlessly show the current network topology, as well as to easily notice any link failures.
Next, we used Python to parse NetFlow version 5 packets to enhance our understanding and troubleshooting of NetFlow. We also looked at how to use ntop and Python to extend ntop for NetFlow monitoring. sFlow is an alternative packet sampling technology. We used sflowtool and sFlow-RT to interpret sFlow results.
In Chapter 9, Building Network Web Services with Python, we will explore how to use the Python web framework Flask to build network web services.
