ntopng (Enterprise M/L license is required) integrates with ClickHouse to store historical flows and alerts. ClickHouse is an high-performance SQL database. To install ClickHouse refer to the official guide.


The ClickHouse database can be executed anywhere, both locally on the machine running ntopng or on a remote machine. However, clickhouse-client must always be installed locally as it is used by ntopng to connect to ClickHouse. This installation guide explains how to install it.
