Example Python Script for Nexus 3K

A Sample Client/Server, Agent Based, Network Monitoring Application

• Starting Server Component• It’s now awaiting client connections

• Starting Client (Agent)Component

• Agent output right after client is started• Displays packets sent every 5 seconds• Wouldn’t really display this in prod, but good for demos.

• Server Side• Still the same – no triggered events yet

• Sending packets out eth0 on client to trigger an event

• 4 packets sent (it triggers >= 4, i.e. >3)

• Client output right after 4 pings were sent• Client displays output showing an event has

occurred

• Server Side AFTER trigger• Displays event output in JSON format

• RESTARTING CONTINUOUS PINGS ON CLIENT

• Client output during continuous pings • Continuous trigger events

• Server output during continuous pings • Continuous trigger events

• The server shouldn’t just display or accept logs.

• It should be used to create a feedback loop.

• There is so much data in network devices that is yet to be extracted
