Only Asset Hierarchies that has been deployed will be selectable for visualization in the Time Series Explorer. * **Solution**: 1. Check that the Asset Hierarchy has been deployed in the [Device Configuration](/management-portal/management/device-configuration.md). 2. Deploy the Asset Hierarchy to a Device. *** ### **No data displayed in Historical Data View** * **Cause**: The selected tags might not have historical data available for the chosen time range. * **Solution**: 1. Check the time range selection in the timeline at the top of the Historical Data View to see if the selected asset hierarchy contains any data in the data store. 2. Check the time range selection in the timeline at the top of the Historical Data View and adjust it to a period where data is expected. 3. Ensure the tags are deployed and have been collecting data. 4. Confirm the tags have been properly configured to send data to the Asset Hierarchy’s data store. *** ### **Real-time data not streaming** * **Cause**: The tag may not be correctly deployed or configured for live streaming. * **Solution**: 1. Verify that the tag is currently deployed to a device in the Asset Hierarchy. 2. Ensure the data collector responsible for the tag is active and correctly configured. 3. Check that the tag’s resolution is set to seconds rather than milliseconds, as finer resolutions may cause performance issues. 4. Confirm that the Edge device is connected, indicated by the Live Data Stream icon in the toolbar. *** ### **Slow or delayed data rendering** * **Cause**: Excessive data or high-resolution tags may cause rendering delays in the graphs. * **Solution**: 1. Use the resolution slider in the Historical Data View to aggregate data into larger bins for improved performance. 2. Reduce the number of tags added to the time series graphs simultaneously. 3. Check network latency if using remote connections to access the Asset Hierarchy. *** ### **Tag appears greyed out in Hierarchical- or List View** * **Cause**: The tag is not currently deployed to a device. * **Solution**: 1. Use the “Hide undeployed nodes” toggle to simplify the view and focus on active tags. 2. If the tag has historical data, it can still be added to the Historical Data View for analysis. *** ### **Measurements appear incorrect or inconsistent** * **Cause**: Tag configuration errors or device calibration issues may lead to inaccurate data. * **Solution**: 1. Validate the tag’s configuration in the[ Asset Designer](/management-portal/designer/assets/asset-hierarchies.md) to ensure proper setup. 2. Check the connected device for any calibration or sensor issues. 3. Compare measurements with known benchmarks or reference values. *** ### **Cannot add more Real-time streams** * **Cause**: The maximum number of simultaneous real-time streams has been reached. * **Solution**: 1. Stop one of the existing streams by clicking the Stop button in the Tag list table. Then start the Tag you want to stream- 2. Increase the limit of real-time streams in [Platform Settings](/management-portal/platform-settings.md), if your environment allows for additional capacity (This requires administrator privileges). *** ### **Time range selection not showing data** * **Cause**: The selected time range may not align with the stored measurements in the data store. * **Solution**: 1. Check the time range distribution graph in the timeline to ensure data exists within the selected range. 2. Use the Timeframe dropdown to refine the time selection. 3. Expand the time range to ensure coverage of any sparse data periods. *** ### **Graphs not updating after adding tags** * **Cause**: The page may not have refreshed the data correctly. * **Solution**: 1. Use the Refresh button in the toolbar to reload the Asset Hierarchy and tag data or refresh the entire webpage using F5. 2. Confirm that the tags have been properly added to the Tag list and are active for visualization. 1. **No Data Displayed**: * Ensure the selected tags are active and have associated data. * Check the timeline range for availability of historical data. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.tricloudnexus.io/management-portal/insights/time-series-explorer/troubleshooting.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
