HowTo Monitor SNMP Interfaces Utilisation and Congestion Rate

Recently, we added the ability in ntopng to monitor link utilisation using NetFlow/IPFIX. In this post, we want to show you how we further improved those functionalities by leveraging SNMP to monitor the status of many devices (interfaces) simply. SNMP is a well-known protocol used for monitoring network devices, and ntopng uses it to poll and gather information from them. ntopng computes the interface usage by using a simple proportion between the traffic metered via SNMP and the interface speed.

Monitoring Network Devices with ntopng and SNMP

Summary SNMP is widely used for network monitoring. Being able to remotely monitor network devices is fundamental to have a clear picture of present and past network health. ntopng systematically interacts with SNMP devices to provide historical and real-time insights on the network. ntopng SNMP support Simple Network Management Protocol (SNMP) is one of the de-facto standards used to remotely monitor network devices such as routers, switches and servers, just to name a few. With ntopng Enterprise it is possible to consistently and programmatically interact with those devices to have a real-time view …
