What is the difference between NetFlow and syslog?

NetFlow was introduced on Cisco routers and provides the ability to collect IP network statistics, including packet counts. It will not alert on system events like interface down. Syslog does not have any overhead but NetFlow may place a load on CPU when utilized. Also, the volume of NetFlow data can be quite large.

What is the difference between NetFlow and SNMP?

SNMP vs NetFlow: NetFlow emerges as a more compact protocol than SNMP that scales better for performance collection and network traffic management. A couple of big difference between SNMP vs NetFlow are: SNMP can be used to collect CPU and memory utilization and that just isn’t available yet using NetFlow.
