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. The interface speed is read by default from SNMP, but it can …
