Implementing syslog versus SNMP can meet the design requirement of gathering information such as flows and client connectivity. Syslog can collect and report various types of events, such as VPN connectivity, uplink connectivity, DHCP leases, firewall rules, IDS alerts, and security events. Syslog can also provide detailed information about the flows and client connectivity on the network devices, such as source and destination IP addresses, ports, protocols, bytes transferred, etc. SNMP, on the other hand, can collect and report various statistics and information about the network devices, such as CPU utilization, interface status, memory usage, etc. However, SNMP does not provide as much information about the flows and client connectivity as syslog does.
