What often causes table cells to appear empty in Data Explorer?

The reason why table cells may appear empty in Data Explorer is primarily due to splitting entities not matching. In Dynatrace, when you configure a query to analyze data, you often use splitting entities to break down the results into more meaningful segments. If the splitting criteria applied do not correspond to the available data points, the resulting table will have empty cells for those segments where there are no matching data points.

For instance, if you are trying to analyze performance metrics split by a particular host or service that no longer exists or is misreferenced in the query, there will be no data to populate those cells, leading to an empty appearance. This highlights the importance of ensuring that the entities being queried exist and are accurately defined in the context of the data available for analysis.
