View Data Sources
To see which index a data view is pulling the data from, check the respective data views in Stack Management -> Data Views.
If you need to create your own data views, follow this guide: Creating Data Views in Kibana.
For example, if you click on “Edit Visualization” on a chart, you will see that the table chart is getting data from the DV-PT-PJT data view.
You can then view the DV-PT-PJT data, check the indices from where the data is getting pulled, and add a timestamp filter according to your requirements.
