Choose data source from server

Connect to InfluxDB

Create InfluxDB data source

After clicking the data source, the NEW DATA SOURCE configuration panel opens. Follow the given steps to create an InfluxDB data source:

  1. Enter a name and description (optional) for the data source.

  2. Enter a valid InfluxDB server or host name in the ServerName text box.

  3. Enter the port, in which the server is running in the Port text box.

  4. Choose None or Server Authentication in the Authentication Mechanism combo box.

Here is the Bold BI supported features in InfluxDB connector

IMPORTANT: InfluxDB is a time series database, so few limitations for InfluxDB connector in Bold BI live mode connection.

NOTE: Joins are not supported for InfluxDB data source in Bold BI.

Group by and Order by

InfluxDB is a time series database. The data can be ordered only by using the time column and can be grouped only by time intervals.
