NetFlow is stateful and works in terms of the abstraction called a flow: that is, a sequence of packets that constitutes a conversation between a source and a destination, analogous to a call or connection.Ī NetFlow exporter device collects data on the IP traffic entering/exiting the device it inspects packets and groups them into flows by inspecting particular fields: the source and destination addresses, protocols, ports, etc.ĭata on observed flows is rolled up from the packets and cached locally (in the flow cache), then it’s periodically exported to the collector based on active and inactive timeouts. Application protocol rates in bits per second.NetFlow is a network protocol developed by Cisco that notes and reports on all IP conversations passing through an interface.Application protocol rates, in bits per second.Traffic totals, both in Bytes and packets.Traffic rates, in bits and packets per second.The type of metric is followed by the unit of measure (i.e., bpsįor bits per second, pps for packets per second, and bytes).

To set up the datasource visit Grafana Datasources page and select the Navigate ntopng data from inside the beautiful Grafana dashboards. The official ntopng Grafana datasource plugin lets you quickly To start using InfluxDB with ntopng please refer to the documentation: ntopng Datasource For this reason, support and development for this plugin have been discontinued in favour of the InfluxDB Grafana datasource plugin. Ntop has redicected resources and focus to the integration of InfluxDB, which is natively supported in ntopng starting from version 3.8.
