Grafana
ntopng-generated historical flows and alerts can be visualised in Grafana.
When using ClickHouse as the timeseries backend, ntopng provides a built-in Grafana dashboard that can be downloaded directly from the ntopng Preferences page. See the Timeseries page for details on how to download and import the dashboard.
For additional Grafana dashboard examples and configuration templates, refer to the ntopng Grafana repository on GitHub.
