- 1. A Sample Client/Server, Agent Based, Network Monitoring Application
- 2. • Starting Server Component • It’s now awaiting client connections
- 3. • Starting Client (Agent)Component
- 4. • Agent output right after client is started • Displays packets sent every 5 seconds • Wouldn’t really display this in prod, but good for demos.
- 5. • Server Side • Still the same – no triggered events yet
- 6. • Sending packets out eth0 on client to trigger an event • 4 packets sent (it triggers >= 4, i.e. >3)
- 7. • Client output right after 4 pings were sent • Client displays output showing an event has occurred
- 8. • Server Side AFTER trigger • Displays event output in JSON format
- 9. • RESTARTING CONTINUOUS PINGS ON CLIENT
- 10. • Client output during continuous pings • Continuous trigger events
- 11. • Server output during continuous pings • Continuous trigger events
- 12. • 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 THE END
