SNMP ==== ntopng (Enterprise) is able to perform SNMP monitoring, providing an overall visibility of every monitored device, and allowing a drill-down of the monitored data down to every single device interface. Historical charts are available to understand the patterns of traffic across devices and interfaces. Alerts can be created, for example, when an interface changes its status from up to down, or viceversa. These blog posts explain in detail how SNMP monitoring in ntopng works, and what are the best practices for its setup: - https://www.ntop.org/ntopng/advanced-snmp-monitoring-with-ntopng/ - https://www.ntop.org/ntopng/monitoring-network-devices-with-ntopng-and-snmp/
