To chart counters, there is no need to take the derivative. For the sake of example, a gauge panel with interface traffic can be created as follows. Indeed, continuous incrementing values are only meaningful when derived, that is, when compared with their adjacent values. Likely, to chart a gauge, a query will have to take the non_negative_derivative. Counters are for continuous incrementing values such as bytes sent and received.Gauge are for things like the number of active flows, or active hosts.Gauges and counters are the two types of timeseries exported by ntopng: The query builder helps constructing the classical SELECT-FROM-WHERE clauses to pick the right data.ĭifferent queries need to be constructed, depending on whether a gauge or a counter is being charted. Timeseries data are added to panels using the Grafana query builder. Now that Grafana is properly set up to extract timeseries data from InfluxDB, new panels with ntopng timeseries data can be added to dashboard panels. Adding Grafana Dashboards panels with ntopng data NOTE: The Grafana ntopng plugin datasource is outdated and should not be used. Then, it is enough to specify InfluxDB connection parameters.Ĭlicking on “Save & Test” will automatically test the connection and save it. To create the datasource, pick the Datasources entry under the Grafana configuration menu, and add a new datasource of type InfluxDB. The same InfluxDB connection parameters specified above to configure ntopng can be used also to create a Grafana InfluxDB datasource. Once preferences are saved, ntopng will start exporting timeseries data to InfluxDB.Ĭonfiguring the Grafana InfluxDB Datasource Then, it suffices to configure InfluxDB connection parameters. To configure ntopng to export timeseries data to InfluxDB, visit the ntopng Timeseries preferences page, and pick InfluxDB as driver. Configuring ntopng to Export Timeseries Data to InfluxDB This post aims at covering the topics above to serve as reference for those who want to create Grafana dashboards. Adding Grafana Dashboards panels with ntopng data.Configuring the Grafana InfluxDB datasource to extract timeseries data from InfluxDB.Configuring ntopng to export timeseries data to InfluxDB.Application protocol rates in bits per second.Creating Grafana dashboards out of ntopng data basically boils down to:.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).

Interface and host metrics have a suffix that contain the type of Identify an host are prefixed with a host_ followed by the actual Metrics that identify an interface are prefixed with a interface_ Once the datasource is set up, ntopng metrics can be charted in any A green message Success: Data souce is workingĪppears to confirm the datasource is properly set up.

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.
