+<summary>Handling NULL values</summary>
+
+Queries that return `NULL` values are supported, but they are not rendered as metrics. It's useful for situations, when
+the result set depends on some conditions, so it may be empty. Whenever a query returns `NULL` values, the exporter
+logs a message at the `Debug` level. If your query constantly returns `NULL` values, it most likely means that you need
+to revisit your query logic.
