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.
To store data, you must select the Enable Data Store option for the device you want to store data for. You have the option of storing data for a specific period of time to support analytics on the historic data in the Retention Hours field. See Enable Data Store to learn more.
Manufacturing Connect Edge 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 Manufacturing Connect Edge device has sufficient computing resources.
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.
