Using Built-in Data Sources¶
DTV supports multiple types of built-in data sources: the Time Series Database (TSDB), the Common Data Service (CDS) and the Metric Management (Olap).
Preparing the Built-in Data Sources¶
TSDB¶
The EnOS Time Series Database provides access to time series data generated by stream processing engines or devices.
- Obtain the Time Series Data (TSDB).
- Create the corresponding storage policy in Time-Series Data Management, see Storage Policy for EnOS Cloud Users.
Data Sources | Description |
---|---|
LatestData | The latest data of the specified measurement points of specified devices. |
Current Day Electric Power | The accumulated power consumption/production data of specified devices from 00:00 (local time) of the current day. |
Electric Power | The power consumption/production data of specified devices within a certain period. |
DI Data | The status change (DI) data of specified devices within a certain period. |
AI Raw | The original AI data of specified measurement points of specified devices within a certain period. |
AI Aggregation | The AI normalized data of specified measurement points of specified devices within a certain period. The queried data can also be aggregated by the specified logic. |
Generic | The generic data of specified measurement points of specified devices within a certain period. |
RAW DATA | The original data of specified measurement points of specified devices within a certain period (covering AI, AI Normalized, DI, PI, and Generic data types) and perform application development. |
For more information, see Time Series Data Management Overview.
Common Data Service¶
EnOS Common Data Service (CDS), providing access to EnOS data such as cross-domain KPIs, metrics, measurements, alert data etc.
- Obtain the Common Data Service.
- Complete pre-configuration. For more information, see Setting up EnOS Common Data Service.
Data Sources | Description |
---|---|
Realtime | Real-time data, the latest data values or data containing the latest data values for a certain period (current day, current month, current year or all) are supported. |
Timeseries | Time-series data, data for a certain period. |
Alarm | Alarms, alarm data for site devices. For example, using the CDS - Alarm data source requires that an Alarm Rule be associated at the OU level. |
Topology | Real-time data with information on the hierarchical structure of the target device (typically used in the Device Status widget). |
Record | Operation records (generally used in the Table widget). |
For more information, see EnOS Common Data Service.
Metric Management¶
EnOS Metrics Management Service provides one-stop metrics standardization definition, metrics configuration calculation and metrics uniform query service.
- Obtain the Metric Management
- Create the required metrics, fact sheets and dimension sheets. See Develop photovoltaic power generation, temperature and irradiation indicators.
Data Sources | Description |
---|---|
Metric | Query metric data. |
Fact Sheet | Query fact table and dimension table data. |
For more information, see Metric Management.
Enabling Built-in Data Sources¶
Enable built-in data sources by following these steps:
- Select Dashboards > Data Source from the left navigation pane.
- Select Built-in Data Sources tab to access the list of built-in data sources.
- Toggle their respective Enable toggles.
