Discontinuation Notice
ntop has redicected resources and focus to the integration of InfluxDB, which is natively supported in ntopng starting from version 3.8. For this reason, support and development for this plugin have been discontinued in favour of the InfluxDB Grafana datasource plugin https://grafana.com/docs/features/datasources/influxdb/.
To start using InfluxDB with ntopng please refer to the documentation: https://www.ntop.org/guides/ntopng/basic_concepts/timeseries.html#influxdb-driver
ntopng Datasource
The official ntopng Grafana datasource plugin lets you quickly navigate ntopng data from inside the beautiful Grafana dashboards.
Setting Up the Datasource
To set up the datasource visit Grafana Datasources page and select the
green button Add a datasource. Select ntopng as the datasource
Type in the page that opens.
The HTTP url must point to a running ntopng instance, to the endpoint
/lua/modules/grafana. The Access method must be set to
Direct. An example of a full HTTP url that assumes there is an
ntopng instance running on localhost port 3001 is the following:
http://localhost:3001/lua/modules/grafana
Tick Basic Auth if your ntopng instance has authentication enabled
and specify a username-password pair in fields User and
Password. The pair must identify an ntopng user. Leave the Basic Auth checkbock unticked if ntopng has no authentication
(--disable-login).
Finally, hit the button Save and Test to verify the datasource is
working properly. A green message Success: Data souce is working
appears to confirm the datasource is properly set up.
Supported metrics
Once the datasource is set up, ntopng metrics can be charted in any Grafana dashboard.
Supported metrics are:
- Interface metrics
- Host metrics
Metrics that identify an interface are prefixed with a interface_
that precedes the actual interface name. Similarly, metrics that
identify an host are prefixed with a host_ followed by the actual
host ip address.
Interface and host metrics have a suffix that contain the type of
metric (i.e., traffic for traffic rates and traffic totals orT
allprotocols for layer-7 application protocol rates).
The type of metric is followed by the unit of measure (i.e., bps
for bits per second, pps for packets per second, and bytes).
Interface Metrics
Supported interface metrics are:
- Traffic rates, in bits and packets per second
- Traffic totals, both in Bytes and packets
- Application protocol rates, in bits per second
Host Metrics
Supported host metrics are:
- Traffic rate in bits per second
- Traffic total in Bytes
- Application protocol rates in bits per second.
