DataHub
The DataHub module allows you to store data polled from the connected devices with data storage enabled. A variety of data formats are supported.
You can choose to store data for a specific period of time to support analytics on the historic data. See Manage Tags to learn more.
Belden Horizon Data Operations stores the polled data in a NoSQL time series database.
Limitation: InfluxDB initialization for large databases takes a long time with high CPU utilization. Ensure the Belden Horizon Data Operations device has sufficient computing resources.
Depending on the version of Belden Horizon Data Operations you are using, you will see one of the following UI configurations.
Belden Horizon Data Operations Version 3.3.2 and Earlier
You have the option of configuring an internal or external InfluxDB timeseries database.
The DataHub UI is divided into three panes:
- Configuration: Toggle the timeseries database, change source type, and perform additional customizations.
- DB Management: Expand a database view to display your connected devices, remove specific data storage for a connected device, and delete the timeseries database.
- DB Users: Add and delete database users, reset a user's password, add privileges to a user, as well as view the user list.
Belden Horizon Data Operations Version 3.5.2 and Later
You can only configure an external InfluxDB timeseries database from the DataHub > DataHub pane.
The DB Management and DB Users panes don't apply to the database configured from the DataHub > DataHub pane.
Important: The DataHub (Legacy) configuration page will be removed in a future release. You will need to create new configurations and migrate existing DataHub (Legacy) configurations to the DataHub page.
