What is the difference between SNMP and NetFlow?
SNMP datagrams are continuously sent across the network in real-time (i.e. every second) as responses to SNMP queries, while the exporting of NetFlow records depends on active/inactive timers. It may take up to 30 minutes to export a flow when NetFlow is used.
Which technology is used for analyzing and monitoring network traffic in network and information flow?

What are the different types of network monitoring?
4 categories of network monitoring
- Availability monitoring. Availability monitoring is the simplest way for network teams to know if a device is up and operational.
- Configuration monitoring.
- Performance monitoring.
- Cloud infrastructure monitoring.
How does network monitoring work?
Ping: A ping is one of the most basic techniques that monitoring software uses to test hosts within a network. The monitoring system sends out a signal and records data such as whether the signal was received, how long it took the host to receive the signal, whether any signal data was lost and more.
