Timeseries Database
Timeseries Driver

The driver used for storing and retrieving timeseries data.
Note: It's possible to use InfluxDB v.2 with a compatible v.1 bucket, however the Retention and the Buckets have to be managed by the InfluxDB GUI.
Minimum InfluxDB version supported: 1.5.1

InfluxDB Timeseries and Top Talkers Retention

Retention (days) for InfluxDB timeseries and top talkers. Default: 30 days.
Note: If InfluxDB is currently used, to change the retention policy correctly, ntopng restart is needed.
Note: If InfluxDB v.2 with a compatible v.1 bucket is used, the retention policy does not work.

Interfaces Timeseries
Traffic

Toggle the creation of bytes and packets timeseries.

Layer-7 Applications

Toggle the creation of Layer-7 application timeseries. Creating a timeseries per application requires more disk space and extra I/O and, in general, it is not needed.

Split Timeseries Directions

Toggle between displaying a single total traffic timeseries (RX + TX) and separate timeseries for RX and TX. When the 'Total' option is selected (default), a combined timeseries is generated. Otherwise, separate timeseries are created for each direction (RX and TX).

Local Hosts Timeseries
Host Timeseries

Enable full host timeseries creation (full), limit it to bytes and score (light), or turn it off.

One-Way Traffic Timeseries

Toggle the creation of timeseries for one-way traffic. One-way traffic is often generated by remote hosts performing probing, so it is advisable to keep this disabled.

MAC Addresses Timeseries
Traffic

Toggle the creation of bytes and packets timeseries.

System Timeseries
System

Toggle the creation of timeseries for monitoring the system, e.g. Redis timeseries, CPU/Memory timeseries...

Other Timeseries
VLANs

Toggle the creation of bytes and applications timeseries for VLANs.

Autonomous Systems

Toggle the creation of bytes and application timeseries for autonomous systems.

Countries

Toggle the creation of bytes timeseries for countries.

Internals

Toggle the creation of internals timeseries, e.g., hash tables entries, periodic activities duration and number of timeseries points written, scripts duration and number of calls.
